Protect your pneumatic systems and air compressors with this premium 2-pack of Fukaisu brass pressure relief valves. Engineered from solid brass, these components offer exceptional durability, resisting tarnish and maintaining high-temperature ductility even in harsh industrial environments. The robust construction ensures long-lasting performance, providing reliable safety for your equipment without the risk of corrosion or premature wear.
Designed for automatic safety, each valve is preset to release excess pressure at 175 PSI, effectively preventing overpressure damage to tanks and connected machinery. Once the pressure drops back to a safe level, the valve reseals automatically, ensuring continuous protection without the need for manual intervention. This feature is critical for maintaining the integrity of air compressor tanks and preventing costly equipment failures.
Installation is straightforward thanks to the standard 1/4-inch NPT male thread, which fits securely into most air compressors, water pumps, and pneumatic tools. The precision threading guarantees a leak-proof connection, allowing for easy setup even in tight spaces. Whether used as an air compressor pop-off valve, a pressure regulator, or for water and oil discharge, this versatile valve performs reliably across a wide range of temperatures and applications in workshops, garages, and industrial settings.
