Replacement safety relief valve with a Viton® O-ring for pressure washing and cleaning equipment. The new-style valve features a changeable O-ring and comes standard with Viton for reliable chemical resistance. An EPDM O-ring is available by request and provides improved resistance to certain solvents and alcohol-based chemicals.
For applications experiencing low maximum pressure, consider the original-style SFTY-1 safety relief valve. The original style uses a stronger spring and is designed to hold higher pressure. Original-style relief valves are available with EPDM sealing material only.
