Meter Star 3/8 in Male Flare to 3/8 in Male NPT Brass Union Adapter, 2 Pack for Propane Grill Gas Lines

Gas, fuel, and fluid systems often require a secure transition between different fitting types. This Meter Star 2-pack brass union adapter is designed to connect a 3/8 in male flare fitting with 5/8-18UNF threads to a 3/8 in male NPT fitting, helping complete gas line and fluid line setups with the correct thread configuration.

The brass construction offers durability and corrosion resistance compared with iron or galvanized fittings. Its half-union design allows easier connection and disconnection of tubes than standard couplings, making it useful for installations that may need service, adjustment, or reconfiguration.

Suitable applications include LP gas, natural gas, fuels, grease, refrigeration, and hydraulic systems in low to medium pressure lines. Common use scenarios include propane BBQ grill hookups, gas heaters, fireplaces, RV trailers, and industrial instrumentation setups.

This 2-piece set is practical for completing multiple connection points or keeping an extra brass gas line adapter available for future maintenance. Confirm thread type, fitting size, and system requirements before installation.
