Product Code: SW78EV

Complete Exhaust valve assembly. 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.
This doesn't include any seals except the exhaust. Tear down help.
