Instrumentation Orifices & Snubbers - NOSHOK

NOSHOK press-fit brass orifices or threaded 316 stainless steel orifices are available on all NOSHOK pressure gauges and most NOSHOK transducers. They are standard with a .012" I.D or .032" I.D, depending on the model. These orifices don’t take up space, as they are inserted inside the NPT. They are an economical solution for managing pressure fluctuations in dynamic applications.

We also offer piston type and sintered snubbers. Our piston type snubbers resist clogging and are self cleaning. They are supplied with five different sized pistons to ensure the correct amount of snubbing for virtually every application. They are available in brass and 316 stainless steel in 1/4" NPT, 1/2" NPT or 7/16-20 SAE-4.

NOSHOK sintered snubbers increase gauge readability by smoothing out pressure surges, pulsations and spikes, and eliminate instrument failure due to pressure shock. Snubbing action is achieved by utilizing a corrosion resistant 316 stainless steel sintered disc, which is held in place by way of a 316 stainless steel set screw.  Unlike the competitor’s crimped method, NOSHOK sintered snubbers allow easy cleaning or replacement of the sintered disc by simply removing the set screw, replacing the disc and then re-inserting the set screw, eliminating the need to replace the entire unit if a new disc is required. This type of built-in versatility greatly increases the snubber’s longevity, durability and dependability.
 
Five basic discs are available for each sintered snubber to accommodate specific application needs. Exotic materials or intermediate disc grades are also available on a per order basis. These snubbers provide long service life with no moving parts to wear out.
