USFT USFT fill port problem... Where to order O-Rings?

EDITED TO ADD: Where would I order the #005 & #011 for the USFT? The O-Ring store does not seem to have them.




So it's been a buncha years since I was active on any of these boards. I'm resurrecting some of my shooters and selling a few in the collection safe to start up again.



Maintenence is first.


I went to fill my USFT and the fill port is leaking upon filling. I'm guessing it is an easy fix if I can find the part. Where would one acquire this part. If even possible.

Would love to see pics of the USFT.


Picture is probably 10 years old

Lots and lots of debate on oring material and durometer...so I'm going to carefully stick my neck out here, with the caveat to do your research and decide what you think is best....

I'm not saying these are the best, just helping you navigate the website for some examples of the sizes you were told you need. And I'm also not endorsing the 005 and 011 sizes as what you need b/c I've never needed to personally replace them in my USFT.

If you decide on 90D Urethane....these .....
and the AS568-005 is what you're looking for to specify the sizes.

90D are hard. Tougher to get in their grooves, but better for abrasion and generally thought to have a longer life. They're also a bit more fussy to get them to hold air than softer durometers...


If you decide on 70D buna as the right choice for you....

70D isn't as hard and generally won't last as long as a 90D, but are easier to get to seal and hold air.

SOOO much debate about the various compounds orings are made out of too. Again, I'm not saying these are right or are the best choices for what you need, the links are just to demonstrate what you're looking for when told 005 and 011.

Hey Now, I appreciate the links and input. I am think I am going to look into the 70D for the USFT. I still need to talk to someone prior to buying the seals. But all this helps a lot. Thanks!
