AutoFlare

Streamline your gas-piping installations with the high-performance AutoFlare® fittings from the TracPipe® / CounterStrike® system. These snap-on, self-flaring fittings are designed for professional reliability and ease of use—making them a smart choice for contractors and DIYers alike.

What sets AutoFlare® apart? These fittings are self-piloting and tool-friendly, requiring no specialized flaring equipment. The joint seals with standard spanner torque and features a metal-to-metal seal for enhanced durability.

In this collection you’ll find:

  • Straight adapters that transition CSST to traditional NPT fittings—available in multiple sizes (¼″, 3⁄8″, 1⁄2″, 3⁄4″, 1″). 

  • Couplings, reducing fittings and tees to support system branching, transitions and layout flexibility.

  • Flange and wall-box fittings with mounting plates for appliance installations and service-friendly access. 

  • Certified for both residential and commercial use—with comprehensive manufacturer specs for pressure, temperature and compatibility.

Why shop this collection at Big Frog Supply? Because we understand plumbing, gas piping and irrigation systems—and we offer expert-curated product selections, clear installation guidance and friendly service. With AutoFlare®, you reduce install time, minimize leak risk and simplify system commissioning.

Pro tip: Before you install, verify that you’re working with a compatible CSST brand (e.g., TracPipe® / CounterStrike®), select the correct size and transition, and follow bonding/grounding instructions as specified by code. Because AutoFlare® is tool-friendly doesn’t mean corner-cutting is OK. Proper prep and torque matter. Browse the collection, pick your fitting type and size, install with confidence—and reduce installation headaches.
