Pro-lite valve material

[markdem]

What is this stuff? Flexes quite a bit - not quite as much as a 70 durometer o-ring but still noticably squishy. Im thinking 90 durometer polyurethane?

[Chappy]

I’m starting to think the seals in og tippmanns were made of Poly-unobtainathane. But I believe you are correct

[mikeds80]

Have you had luck replacing the material with a modern oring? I have two prolites that likely need valve work.

[markdem]

I have not yet ordered any material. Im building a list of stuff i want from mcmastercarr.

Flip it.

[Myrkul]

100% this. Let it soak overnight in oil, flip it over and throw it back in. It has worked every single time I've done it.

[Axel]

Flip it.

Bop it.

Twist it!

You planning on making some new ones I take it Mark?

[William the Third]

Twist it!

Load it!

[markdem]

Chuck E Ducky yes i plan to make new seals. Along with some different style valves. just messing around with a bunch of old broken guns i got for cheap

[Chuck E Ducky]

Cool I just put together a Prolite build. Interested to see what you come up with. I would love to find a way to lighten up the trigger pull.

File it

Are you reducing the height also, as well as filing the grooves?

[BretG]

Yes. The more internal volume you have, the better. Also I do the front poppet with all 6 facets filed and the back poppet only 2. This sends more air forward.

Thanks for the clarification
