Snap-Tite Gaskets for Bevel Seat Sanitary Fittings

All Snap-Tite gaskets are made from Buna-N rubber. Standard packaging is 100 per box. Use Apex style “molded” or “flat” gaskets for bevel seat fittings. See Apex “-XT” PTFE (extra thin) bevel seat gasket series. Refer to the following part numbers:

1″: Part # Haynes 1
1-1/2″: Part # Haynes 1.5
2″: Part # Haynes 2

Apex Flat Buna-N Rubber


Apex “flat” gaskets for bevel seat pipe fit easily into ferrule for quick installations and excellent serviceability. “Wide Flange” series have a smaller inside diameter to overlap further into the inside of pipe to create extra turbulence.
