Can this union be used for natural & LP gas?

Asked by Camo March 15, 2021

Answer

There are often local code issues with using galvanized fittings on natural gas lines, due to sulfur in the gas and possible corrosion issues with that and any moisture. I recommend that you stick with the regular steel/iron version, with steel pipe, and avoid possible corrosion issues and code violations.

Does this have a rubber gasket?

Asked by Ryan September 13, 2020

Answers

No, there is no gasket included or needed. Sealing is managed by a conical section that engages a match contact ring in the other section.

The connections are for 3/4" tapered pipe thread. Garden hose uses a similar size but straight thread. There is no seat in this fitting to accept the rubber gasket needed to seal to 3/$ garden hose thread.
