RGD resistance, or Rapid Gas Decompression resistance, is a critical property for elastomeric seals used in high-pressure oil and gas environments. When system pressure drops suddenly, dissolved gases in the seal material expand explosively, causing blistering, cracking, or complete seal failure. HPHT seals operating above 10,000 psi and 150°C are especially vulnerable. RGD-resistant ... https://globalsealstech.com/product/rgd-rapid-gas-decompression-o-rings/
