Air compressor owners, these safety relief valves are essential protection for your equipment and safety! Set to release at 120PSI (8 Bar), these brass valves provide critical overpressure protection for your air compressor system. The 1/8 BSP external thread makes them compatible with many compressor models and air systems. Made from durable brass construction, they resist corrosion and provide reliable performance over time. The bright red hat makes them easy to identify and operate when needed. You get 3 valves in the package, which is great for having spares or protecting multiple points in your system. These valves are designed for critical applications on pressure piping and pressure vessels, serving as secondary protection beyond your compressor's primary safety systems. Proper installation ensures that if pressure ever exceeds safe levels, the valve will automatically release air to prevent dangerous situations. Every air compressor system should have reliable pressure relief valves, and these industrial-grade units deliver exactly that. Don't risk equipment damage or safety hazards - install these affordable but crucial safety components and have peace of mind knowing your compressor system has proper overpressure protection. The quality construction ensures they'll perform when you need them most!
