Is there a US source for the valve packing for a Tau Match 7. My recent purchase shot well on bulk fill, but started to leak past the valve when I loaded a crosman 12 gm cylinder. Cleaning, degreasing, tapping, several old xxxwords and some new ones later, it still leaks. TopGun recommends I become a machinist, but I would rather purchase than make. Any sources?

Thanks, Mike

This gets tricky. As best I've been able to tell, there are at least three different sized seals used in Tau-7's over the years. I have some for the MIT collegiate team pistols, but the fist Tau-7 Jr. I tried to repair, the seals were way too large. I had to make my own, and although it's much better, I still have a very slow leak.

One big problem is that the only way to remove the seal involves damaging it, so it's a one way trip.

Pilkguns may be able to replace the seal.

Thanks, I got it working after much magnification and cleaning. Then I cut a Crosman caplet in two, looked then ran to my gas supplier for a CO2 tank.
Thanks again.
