Gas Connection

When it comes to gas piping systems, every joint, adapter and connector matters. The Gas Connection collection at Big Frog Supply brings you fittings and kits designed for secure, code-compliant installations—whether you’re working with CSST, flexible stainless connectors or transitioning between piping types.

In this collection you’ll find:

  • Stainless-steel appliance connectors and flexible gas lines for cooktops, boilers, grills and outdoor fire-pits—packaged and ready for hook-up.

  • Transition and termination fittings (e.g., CSST to black steel pipe, flare to NPT) plus installation kits that include seals, gaskets and required parts.

Why shop with Big Frog Supply? We live in the trenches of plumbing, irrigation and lighting. We know gas-system installs require precision, compliance and durability. You’re not just buying a part—you’re specifying a system that must perform safely for years.

Pro tip: Before you buy—identify your pipe type (CSST, black iron, flexible stainless), verify the connection size and end-type, ensure your fitting is listed for the correct fuel (NG or LP), and follow bonding/grounding requirements for CSST. Always terminate with the correct seal and torque specification per Manufacturer’s Instructions. Using the wrong adapter or skipping a seal can lead to leaks or code failure.

Browse the collection, choose the right fitting or kit for your system, and install with confidence.
