Flashback Arrestor Fuel Gas Torch Inlet 9/16 LH
Torch-inlet flashback arrestor for fuel gas (acetylene/LPG) line — 9/16 LH notched thread, non-return valve, thermal cutoff.
Product Overview
Torch-inlet type flashback arrestor for fuel gas hose line, 9/16 inch LH (notched) male-female in-line body. Left-hand thread is the standard fuel gas connection to prevent cross-connection with oxygen fittings. Suitable for acetylene and LPG/propane. Contains non-return valve and thermal cutoff. EN ISO 5175 / BS 6158 compliant.
LH notched thread prevents accidental oxygen-fuel gas cross-connection. Always verify gas side (oxygen vs fuel) before fitting — both arrestors required on every oxy-fuel outfit.
