Screw Type Rupture Disc Holder

The typical Screw Type Rupture Disc Holder (without rupture disc) is a three-piece unit consisting of a base (inlet), hold down ring, and an outlet nut.

When assembled, with rupture disc in place, the crown of the disc protrudes into the hold down ring. The base and hold down ring grip the rupture disc while the outlet nut provides the compression necessary to create a metal to metal seal.

Fike’s Screw Type Rupture Disc Holders are confined to the 1/2 inch nominal disc size. They are available in four styles: (1) ½30, (2) ½100, (3) S½10, (4) ½SP10.

All these styles may be applied to a pressure system, or set-up, through standard NPT connections.
