Gas Fittings
When dealing with gas piping systems, every connection must perform. Our Gas Fittings collection brings you the trusted adapters, unions, reducers, transitions and accessory components that tie your system together—whether you’re working with CSST, black steel, appliance hook-ups or retrofit installs.
What you’ll find in this collection:
-
CSST-to-threaded adapters, unions and couplings built for corrugated stainless steel tubing systems commonly used in modern gas supply.
-
Appliance connection fittings and kits—brass male/female adapters, unions, reducing fittings—to hook up stoves, grills, boilers and other fuel-gas appliances cleanly and code-compliantly.
-
Transition fittings that adapt between piping types (CSST to NPT, CSST to steel pipe) and accessory parts to support installation (termination plates, unions, reducers).
-
Fittings rated for natural gas and propane applications, certified to industry standards and ready for residential or commercial systems.
Why Big Frog Supply? Because we understand that “just a fitting” can be the difference between safe system performance and trouble. We offer clear spec choices, trusted brands, and installation-smart advice so you build it right the first time.

Pro tip: Before you purchase, identify the type of gas piping you’re connecting to (CSST, black iron, soft stainless), confirm fuel type (natural or LP), ensure certification for the fitting, and check for bonding/grounding requirements on CSST runs. Using matched system components helps reduce leak-risk and keeps installs code-compliant.
Browse the collection, select the correct fitting for your system, and install with confidence.
