Explosive Decompression

Explosive Decompression

Explosive Decompression(ED) or Rapid Gas Decompression(RGD) is a structural failure, a condition that occurs due to gas permeation or dissolution into the seal material. When system pressure decays quickly, the entrapped gas expands, rupturing the o-ring.

Explosive decompression may cause blistering, internal cracking and splitting of parts. Seal & Design has compounds available in EPDM, HNBR, Viton, Aflas, and Chemraz to minimize the effect of explosive decompression.  Please contact our sales staff for a proper elastomer recommendation.
