1 in. and 1-1/2 in. size to spud with 1 or 2 screw(s) fixing

Consider that this kind of pulp and paper sealing with gasket seal can withstand a maximum working pressure of:

  — 30bar (435psi) in case of 1 screw fixing

  — 50bar (725psi) in case of 2 screws fixing

The wetted parts are available in AISI 316L, Hastelloy C276

TM

 and Diaflex (anti-abrasion diaphragm treatment).

While installing, please use the appropriate Viton™ gasket.
