Description
 
Complete Exhaust valve assembly plus the 6 Orings in Mil Spec 90 Urethane. Fits S&W 78 & 79, Daisy 780/790/41. This is not shaped like the original and works better because of it. 100% Urethane seal. Made in USA by Mac1. Heat the entire gun up to toasty so when you first charge it the seals are supple and the pressure is high. Make sure there is no damage to the valve seat where the seal sits. It is very important as the Mac1 seals are hard enough so you can leave the gun charged all the time and to get it to seal initially can be impossible if there is any seat irregularity. Polishing the seat is often required to remove any scratches.

Reviewer: john b from eau claire, WI United States  
I've been trying to get the piston part that this kit contains for a long time. Saw it and ordered as quick as possible!

They shipped it the same day.  Install was straight forward, but tricky getting the small o-rings on.  No brain surgery, just a small stiff part that needs to stretch.  Took a dozen tries and it was dropped a few times too, but perseverance paid off.  All parts installed and back together in about a half hour.

How's it work?  Well, putting in a new co2 and a good smack, yielded nothing.  Sort of anticlimactic, really.  No sound, no hissing no leaking.  Loaded, cocked and fired for the first time in a long while.

Shot a half dozen pellets and after a half hour it seems to still be firing just as quickly.

All I can say is "Thank you!"
