Introducing the Gravitas Ultemate Vac, a revolutionary design and Gravitas' first foray into advanced filling systems. This fountain pen sets a new standard for durability by integrating titanium in critical areas, addressing the common weaknesses found in other vacuum pens.
ULTEM resin is a high-performance polyetherimide (PEI) thermoplastic commonly used in the production of circuit boards, sterilization equipment, and most notably, aircraft components. It offers exceptional strength, stiffness, and chemical resistance, making it a premium material reserved for highly demanding applications.
Crafted with an emphasis on long-lasting performance, the Ultemate Vac uses exceptionally durable materials, with titanium strategically placed to reinforce vulnerable points where other vacuum pens often fail. Despite its sturdy build, the pen remains lightweight, featuring a transparent Ultem section that allows easy monitoring of ink level in the secondary chamber.
Unlike many vacuum pens that rely on glue for assembly, the Ultemate Vac is constructed with threaded components and gaskets, making it easy to clean and maintain. The 25mm-long section, tapering from 11.9mm to 10.2mm, offers a comfortable hourglass shape, familiar to fountain pen enthusiasts, for an ergonomic grip.
The nib is a steel size #6 designed and manufactured by Gravitas, silver color and black color housing - paired with ABS plastic feeders - available a variety of sizes: Extra Fine, Fine, Medium and Broad.
Ultemate Vac is threaded to fit JoWo size 6 nib units - when using non Gravitas supplied nib units you are sole responsible to check the fitment and the instalment of the o-rings and we are not responsible for any damages or malfunctions that may occur in the proces of instalment or use of these nibs or nib units.
With a generous ink capacity of over 2.5ml, plus an additional 0.7ml in the secondary chamber, the Ultemate Vac ensures long, uninterrupted writing sessions. The second chamber is equipped with a shut-off valve to prevent ink mishaps, offering a clean, mess-free experience. For optimal ink flow, it’s recommended to unscrew the end knob during use for a consistent, wet line.
Designed for ease of use, this pen can be posted and fully disassembled for thorough cleaning. A key tip: when removing the nib or cleaning (washing) for re-inking, apply silicone grease to the threads and inside the barrel to maintain a water-tight seal and ensure smooth plunger operation, preventing ink spills or piston head slippage of the rod.
Enhance your writing experience with the cutting-edge and durable Gravitas Ultemate Vac.

Has a slight hard-starting. Probably cuz of the narrow tine but reasonably writes well enough. Listed in my top 3 EDC pens. Vacuum filling system is fine but not as good as 823.
Well the day has finally arrived when my eagerly awaited Gravitas Ultemate Vac turned up on my doorstep. I hastily filled it with blood ( Diamine Red Dragon ) as I thought this the perfect baptism. And wonder of wonders it writes beautifully (unlike me) smoothly with a lovely wet supply from the fine steel nib. Glorious. Please pass my gratitude for a job well done to all staff at Gravitas. I will undoubtedly be making further purchases.
Many thanks and kind regards. Kevin
I’m in love with this fountain pen. It has the smoothest nib I have ever written with. It came in a carrying case, not a regular box, which I really appreciate. Hope to see one with a clip one day :D
Title pretty much says it all. Bought 1 pen with a broad nib. Enjoyed it so much I ordered a second one with medium nib. Medium nib needed just a little adjustment and now it’s just as smooth as the broad which is my favorite pen now. No pocket clip needed :). Thank you for the great pens.
I love the size of this pen. I had ordered a gold nib for the pen and they both arrived on the same day, so I haven’t tried the nib that came with the pen. I own several Gravitas pens so I know that their nibs are great writers. I love the pen.
Many years ago I worked on a project that used Ultem plastic as structural component. Fantastic material and I really enjoyed the unusual color. When I saw Doodlebud's YouTube review, I was intrigued. When they went on sale, I had to have one. Got it the other day and I love it. Got it filled with zero issues, something that I can't say with other vac filler pens I've owned. The fine nib wrote perfectly - no tuning required. I love the weight of the pen - feels not too light - not too heavy - and at least for me, the balance is PERFECT. Don't tell my other pens that I've said this...but I think it's my favorite pen.
Finally found the overall perfect pen for my every day technical office needs! Ordered from Gravitas / Pen Venture on a Monday. Package arrived promptly from dispatch to my doorstep on Friday of same week. Excellent service. Quick delivery. Incredibly great pen and design. Every detail is so well done.
There’s not a single complaint for me on this vac pen or the well thought through (design intent) work that has been put into it (and clearly well refined). Ben Walsh knocked this one all the way out of the park! High value return is what you get - more than what you pay for. Top notch materials and properly designed to be easily cleaned and serviced by the user. Overall perfect weight, balance, and hand feel - posted or not. Exceptional writer out of the box, the Gravitas steel nib is smooth. The Ultemate Vac checks all the right technical and daily user boxes. Bonus feature: you get an amazing fidget bubble in the ink chamber. This pen is a Tank!
Everyone kept telling me to buy the Pilot Custom 823. I must have heard that a thousand times. I have several Pilot pens, a various price points, none of which "Wow" me. They're just ok. When I heard Mr. Walsh himself say (on some You Tube broadcast [I think it was Hemmingway Jones - but I may be wrong]) that he had taken the 823, analyzed it and created a pen that had improved on what he analyzed to the the 823's weaknesses and that pen was the Ultemate Vac, my fingers went to his website and hit "buy." I have it, it love it. I've used it everyday since it has arrived. I don't own an 823, so I can't directly compare it, but I now believe that I don't need to buy another Pilot pen that will end up in my Pilot pen graveyard.
I love extra fine fountain pens. I take copious amounts of notes, and space on the page comes at a premium. This has been THE PEN I've been seeking for years. I've used other big name brands due to their reputation for extra fine. I've had custom needle points that dig into the page. This special nib in this grip section, with this material is a god-send, and I'm ashamed I waited to purchase it. This is easily my "go-to" pen for law school notes and other notes where I need to maximize space AND be comfortable.
S-Tier Pen for sure!!!
A fun, vacuum-fill pen in the ultem format.
If the nib were in a Japanese EF instead of a European EF, it would be even nicer. But, I really like the fact the nib assembly being metal puts the weight on the nib ..., and the vacuum keeps the whole pen body more useful than having a space wasting converter. However, I still find a syringe less messy than trying to top things up using the vacuum, itself. Worth the price for a distinctive vacuum fill.
This has become one of my favorite pens. The weight and feel are perfect. It's an extremely comfortable writing experience. Do not pass up on adding this work of art to your collection!
Duty costs were almost the same as the Pen itself and it is worth every penny. Thank you for making such a wonderful writer that is very smooth.
Extremely well made pen that is robust. The nib is a pleasure to write with. Huge ink capacity, which will be very useful when I'm travelling. Came with a nice case, which was a classy touch. Quickly and securely dispatched. Would recommend!
There are few pens that live up to my expectations, but the Gravitas Ultemate vac piston pen has exceeded mine. It is as beautiful as I hoped it would be, but much more substantial than other ultem pens I have, and feels wonderful on the hand. It is my perfect pen.
Got mine today. Very cool pen but unfortunately one of the worst nibs I’ve ever received on a new pen. Hard starts every time and skips occasionally.
I bought these pens as a gift for my grandson’s graduation. He loved them.
The vax filler is barely fills 1/4 of the way up!
I have a sizeable collection of vac fillers, ranging from inexpensive to expensive.
1. Proportions and Balance -
Doesn't feel back heavy. The center of balance and comfortable grip section makes long writing sessions very comfortable for a pen of this size. The ultem material feels solid.
2. Nib Performance-
I got the medium nib. Smooth, wet and reliable. The ability to swap the nib unit for any Jowo nib unit is a great feature.
3. Ink Capacity-
The 2.5ml capacity of the main barrel is in the same league as the Custom 823, Twsbi Vac 700 etc but what makes this pen stand out is the second reservoir. With a capacity of 0.7ml , its like having a standard international converter worth of ink. This is nice if repeatedly opening the shut off valve is a nuisance. The only vac filler with a similar capacity for the second reservoir that comes to mind is the Visconti Homosapiens double reservoir power filler. But this pen is an order of magnitude more expensive.
One thing I would like to see improved in future iterations is the ease of ink transfer between the main and secondary reservoirs. Sometimes an air bubble develops that interrupts the transfer of ink from main to secondary reservoirs. While this rarely happens compared to other Vac fillers, I would like the transfer to be immediate, without ever having to agitate the pen. Its a minor gripe but contributes to the overall user experience.
The Gravitas Ultemate Vac Ultem is a very good writing instrument. It does it’s job and writes very smooth. I ordered with it a black nib. I like black nibs more than the clean steel ones.
An extremely high quality pen, looks beautiful and writes amazingly well. The elegance, exceptional engineering and detail make it something I constantly want to pick up and enjoy….
Ok, the good and the bad..
I’ll start with the bad, as it’s pretty minor. I did NOT know or realize that after paying so much for shipping ($47, I think it was, for DHL shipping to the US) that I was going to be asked to pay, AGAIN, about another $40 in duty fees. Yes, there are retailers in the US. But I’d rather order directly from the source. With that out of the way, that’s my only complaint.
The pen itself is very stout and robust. It feels great in the hand, and is a very smooth/wet writer with a fine nib. I filled it with Diamine Writer’s Blood, and it's a pleasure to use. I look forward to writing in my journal with it. The cap posts nicely. I LOVE Ultem. I ordered a Dinky in utlem as well, as I’m so impressed with this pen. All fine-nib pens should aspire to write like this.
10/10
Sooooo smooth from the start. Nice case. Lovely quality.
Worth the price.
Customer service also a 10/10
Can’t put this baby down! The weight, size and texture all feel excellent—this is my first Ultem pen and I’m already looking at more. The mechanism is fun to disassemble and put back together. The nib is smooth and hard, exactly how I like them. One issue—the pen writes very wet, maybe get a smaller nib size than what you usually do.
