- Superior Material for Longevity: Crafted from high-strength brass and engineering-grade PTC/PTCR polymers, these fittings resist corrosion and wear. This premium hybrid construction ensures a secure hold on nylon tubing, reduces maintenance needs, and delivers reliable performance even in low-temperature environments
- Certified to FMVSS 571.106 Standards: Engineered to meet stringent DOT and SAE J2494-3 specifications. Designed for use with SAE J844 Type A/B nylon air brake tubing, each fitting is factory-tested for leaks to guarantee minimal pressure loss and maximum safety in critical air brake systems
- Tool-Free Push-to-Connect Operation: Features a user-friendly release mechanism for fast assembly and disassembly. Simply insert the tube until it bottoms out and give it a tug to confirm secure engagement. To release, press the collet and pull the tube out—saving valuable time during maintenance or installation in tight spaces
- Wide Application Range: Ideal for air brake systems on trucks and trailers, cab controls, air suspension, sliding rail systems, tire inflation, and auxiliary air lines on mobile equipment. Withstands extreme temperatures from -40°F to +200°F (-40°C to +93.3°C) and pressures up to 250 PSI
- Factory Leak-Tested for Reliability: Every push-to-connect union undergoes rigorous individual airtightness testing before leaving the factory. We stand behind our quality—if you have any issues, our customer support team is ready to assist you promptly
