If you are experiencing leaking problem with 878SHE gun, please make sure you have the following gasket either on your gun or inside your cup thread.

(Use one of that can stop leaking problem)

We used to call the cups for 878SHE different name under 78S series, now we change them back to 28 series since they are the exactly same cups. The only different is the 78S series has a white cup gasket inside, if you don't have it in your cup and you don't have the gasket on your gun, please contact your local distributor for either one.

Thank you.

 

*****************************

CUP-78SAC = CUP-28AC

CUP-78SPC = CUP-28PC

CUP-78SAC-250 ( CUP-78SAM ) = CUP-28AC-250 (CUP-28AM)

CUP-78SWBPC = CUP-28WBPC

If you use CUP-88 with 878SHE gun, you need gasket, too.
