Noshok orifices and snubbers

Noshok’s orifices and snubbers help protect valuable instrumentation from pulsation and pressure spikes by restricting the flow of rapidly increasing and decreasing pressures.

The 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 0.012 or 0.032″ ID, depending on the model. These orifices don’t take up space as they are inserted inside the NPT. Noshok’s 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. The 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 utilising a corrosion-resistant 316 stainless steel sintered disc, which is held in place by way of a 316 stainless steel set screw.
