1 NPT CONNECTIONSP ressure SnubbersDescriptionA simple in-line element called a pressuresnubber is used to reduce the rate of flowof fluids into pressure instruments and con-trols. A small orifice in an adapter fittingdampens shock and fluctuating pressureeffects by limiting the rate at which flowenters. The smaller the orifice, the greateris the dampening proper orifice size for any applicationdepends upon the size of the pressurizedchamber, the viscosity of the fluid and therequired response time of the sizes from .004" diameter to.
2 020"diameter are available. In general, largeinstrument chambers require large floworifices. Viscous fluids require larger floworifices than low viscosity fluids. Gasesgenerally require small Maximum Operating PressureBrass 2000 psig303SS 4000 psig Flow Direction Suitable for flow ineither direction Orifice Diameter Standard .004",.008", .015", .020".

This slowed responsedampens pressure spikes caused by valves valve opens the pressure in the pilot portincreases slowly. In the case of an air loadedpressure regulator with a snubber, the output alsoincreases gradually rather than measuring instruments are protectedfrom surges when equipped with a snubber.
