Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic service professionals. Before replacing any O-ring, shut off fluid supply and relieve system pressure completely. Lightly lubricate the O-ring with a compatible lubricant before seating to prevent pinching or tearing during assembly. Verify the groove dimensions and dash number match before installation to ensure proper compression and sealing.
