PRESSURE SNUBBER - for dampening and filtering. The snubber has a porous metal disc available in three standard grades of porosity. Due to the large filter surface the snubber has less tendency to clog than orifice type devices. The housing is 303SS and the filter disc is 316SS with a maximum PSI rating of 10 000 at 25°C. (PS-8 series 5000 PSI)

Please note that the finish of pressure snubbers may vary. The flat surfaces on snubbers you receive may have a smooth and machined appearance or they may have a textured, shot-peened appearance. These are merely cosmetic differences that do not affect the functionality and performance of the product.

Rated 5 out of 5 by from stopped pressure fluctuations My digital manifold pressure sensor requires this part, without it my manifold pressure gauge was constantly fluctuating, about +/- 3". Now that I installed the snubber my pressure gauge is rock steady.

Rated 5 out of 5 by from Functions exactly as expected Gauge needle would bounce drastically above 20 psi prior to installing pressure snubber. Afterward gauge needle doesn't bounce, so pressure snubber works exactly as it is supposed to
