Oseco's GR pressure relief devices provide an economical, high-performance solution to the fragility drawbacks of graphite disks. The Fluoropolymer-encapsulated GR series is excellent for corrosive applications, and is nonfragmenting and non-torque-sensitive.

The GR is easy to install, designed to fit standard ANSI flanges, and can also be supplied with a spacer on its vent side to provide interchangeability with existing monoblock graphite disk installations. The spacer may be constructed either of permanently attached Valox® 420, for one-time use (GRO, pictured), or of stainless steel or carbon steel, for reusability and easy attachment (GRR).
