Gas Regulators

Maintaining correct pressure in your gas system isn’t optional—it’s crucial for safety, performance and compliance. Our Gas Regulators collection offers pressure­ control devices designed for natural gas and propane piping systems, appliance hook-ups, service lines and multi-appliance installations.

Whether you’re working on a home boiler, a new cooktop, a fire-feature, or a commercial setup, the right regulator can prevent overpressure, reduce wear, and keep your gas system operating safely. For example, when installing a regulator, it's essential to follow proper orientation, venting and code-compliance.

Why choose Big Frog Supply? Because we understand that gas regulator selection isn’t just about “part fits”—it’s about proper sizing, pressure control, code compliance and safety. Our collection is curated for both homeowners and professionals.

Pro tip: Before selecting a regulator, determine your system’s maximum inlet pressure, required outlet pressure, fuel type (natural vs LP), and whether you’ll need venting or over-pressure relief. Install with correct orientation (look for the flow arrow), protect vents from debris, and always perform a leak test after installation.
