PCR – Precision Cut Reverse

The Oseco PCR cross-scored, reverse buckling rupture disc has been designed to excel in extreme cycling or high vacuum/back pressure applications. 

Reversal occurs when the disc reaches the rated pressure and it opens at the score lines. Its cross-scored design allows this disc to achieve higher burst pressures without fragmenting. 

The PCR is typically deployed in SF6 switchgear applications. For highly corrosive applications, fluoropolymer liners are available on the process side of the disc.
