Oseco's GRO pressure relief devices provide an economical, high-performance solution to the disadvantages of fragile graphite discs.  The fluoropolymer-encapsulated stainless steel GR series gives you superior pressure relief protection for the pharmaceutical and chemical process industries.

The GRO is precision-cut by Oseco's unparalleled in-house, five-axis laser to exacting standards, resulting in a precision disc with burst pressures as low as 2.5psig.  The Oseco advantage is the GR's particular suitability for corrosive applications, since it is non-fragmenting, non-torque-sensitive, and highly resistant to corrosion and breakage.

The GRO is excellent for applications where fragmentation is a problem, due to its non-fragmenting design.  It is an ideal, economical solution for low-pressure explosion prevention.
