WATTS® 0372271 530 Calibrated Pressure Relief Valve, 3/4 in Nominal, MNPT x FNPT End Style, 300 psi Pressure, Brass Body
This 3/4 inch calibrated pressure relief valve is used in commercial, residential and industrial applications to protect against excessive pressure in systems containing water, oil, or air. It consists of a bronze body construction with 3/4 inch NPT threaded male inlet and 1/2 inch NPT threaded female (drain) outlet connections, stainless steel spring, brass bonnet, Buna-N disc, and Buna-N O-ring. Series 530C has a calibrated adjustment feature for setting the valve to the required relief pressure, and is ideal for bypass thermal expansion pressure relief (not ASME approved). It is for use in fire protection systems. The maximum pressure is300 psi (20.67 bar). The adjustable pressure range is 50 to 175 psi (3.45 to 12.06 bar).

Dichtomatik 75102160 O-Ring, 238 Dash Number, 3.484 in ID x 3.762 in OD, FKM, 75 Shore A Durometer, Import, Custom 238-VITON
O-rings are closed circular rings of circular cross-section. They are made through vulcanization from form tools as a complete ring. The sealing function of the O-ring is achieved by the deformation of the cross-section when installed and compressed in its housing. The O-ring can be compressed either radially or axially in its installation housing. In operating conditions the pressure exerted by the media reinforces the sealing function, as under pressure the elastomer material functions as a non-compressible fluid.
