Thermo Scuba 3/8" 3500psi Burst Disk 4-pack. PRD Safety Assembly (Burst Disk Kit)
One-piece assembly for safety and convenience
Ratings are release pressure 5250 psi, not cylinder service pressure (3500psi)
Compatible with DGX, Dive Rite, Thermo, Sea Elite, XS Scuba, Hollis, and Blue Steel valvesFor use in North America, this PRD (Pressure Relief Disk) assembly aka "burst disk" fits the typical 3/8-24 UNF thread PRD openings of all brands of valves sold by Dive Gear Express including DGX and Thermo as well as most other brands such as Dive Rite, Sea Elite, XS Scuba, Hollis, Blue Steel, and late model OMS. However this assembly does NOT fit 1/2-inch PRD openings found on Sherwood, Harrison, Genesis and early OMS brand valves. A one-piece safety assembly eliminates the possibility of mismatched components and reduces the likelihood of accidental incorrect installation of the safety assembly. Pressure relief disks are described by their release pressure, not the cylinder service pressure. This PRD is clearly marked with the release pressure in PSI on the hex head and requires 100-120 in-lb of torque for installation. If the PRD is installed in the scuba valve too tightly it will rupture prematurely, and if installed not tightly enough it will leak.
