General description

Install in-line for a flammable gas. In the event of a flashback, the flash arrestor diverts and extinguishes the flame. The arrestor′s shut-off valve closes, eliminating continued gas feed. Reusable 1/4 in. NPTF connections. The 316 SS flash arrestor is recommended for protecting hydrogen systems in high-purity applications.

Other Notes

Factory Mutual Approved Services only.


For HYDROGEN Service
These arrestors should not be used in installations where it is possible for pure oxygen or gas mixtures containing greater than 20% oxygen to enter the hydrogen system. Models Z261831 and Z261858 flash arrestors provide excellent flashback protection for situations in which air accidentally enters the hydrogen system and a flashback results.

Not for use with SILANE or NITROUS OXIDE
