LibertyCES has documented Fitting in Oxidizers/Disinfectants service, including Hydrogen Peroxide and Chlorine. Wetted materials to confirm: ePTFE. Documented models include Poly Processing Hinged-Weighted Manway and GORE Universal Pipe Gasket. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
Hinged-weighted manway opens at 0.25psi to vent H2O2 decomposition; GORE gaskets carry real third-party chlorine-service certification (Eurochlor, Chlorine Institute).

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Hinged-Weighted Manway rating | 19", 24"; weighted arm in 316 stainless steel; opens at 0.25 psi; used primarily for hydrogen peroxide to prevent pressure buildup during rapid decomposition | Poly Processing — Fittings & Accessories |
| GORE Universal Pipe Gasket chlorine certification | Named in Eurochlor's and the Chlorine Institute's published guidance on gaskets for wet/dry chlorine gas and liquid chlorine service | GORE — Gaskets, Sealants & Compression Packing |
| ePTFE shelf life | Indefinite storage — ePTFE doesn't age | GORE — Gaskets, Sealants & Compression Packing |
| GORE Oxygen Service certification | Tested and certified by Germany's BAM (Federal Institute for Materials Research and Testing) for liquid/gaseous oxygen service in flanged connections | GORE — Gaskets, Sealants & Compression Packing |
The Hinged-Weighted Manway opens automatically at 0.25 psi specifically to vent pressure buildup during rapid hydrogen peroxide decomposition — the same off-gassing failure mode Asahi's Diaphragm Valve requirement addresses at the pipe level, now confirmed at the tank-fitting level too.
H2O2 doesn't just need a resistant gasket, it needs somewhere for the decomposition gas to go — Poly Processing's 0.25 psi hinged manway and GORE's third-party Eurochlor/Chlorine Institute chlorine certification are two real, independently documented answers to two different oxidizer failure modes, not one generic "oxidizer-resistant fitting" spec.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
