  • SMK QB78, XS78, QB79, TH78, XS79 CO2 replacement exhaust (main) valve Modified Exhaust Valve

SMK QB78, XS78, QB79, TH78, XS79 CO2 replacement exhaust (main) valve Modified Exhaust Valve

Our Modified Exhaust Valve designed for more power, for the SMK QB, XS, TH 78, 79 models 

Ours have a Stainless Steel shaft rather than the standard mild steel one 

Also comes with the seal already to be fitted 

The exhaust valve will unscrew so you can change the seal 

The standard one is just pressed together 

When fitting the seal to our valve, just unscrew the shaft from the brass head, then pick out the seal 

Push in the new seal with the larger hole facing outwards and the smooth side facing outwards 

put a tiny amount of Locktite on the threads of the shaft and screw in the shaft until it is level 

Do not over tighten 

Model 78 / 79 Replacement Valve Stem / Exhaust Valve 

XS 78 Exhaust Valve is pressed together so you cannot change the seal 

Ours is made to give more power and unscrews so you can change the seal 

When replacing the seal make sure you put the new seal in with the smooth side facing outwards 

The stainless steel shaft can be gripped by placing it in a vise or drill chuck, and then screw into the brass head, if it slips then gripping with a good piece of wet and dry would help 

comes in 3 parts like shown in image

Model 78 and 79 CO2 replacement exhaust (main) valve
