The WIKA brass adjustable throttling snubber has an adjustable needle valve to restrict flow under varying operating conditions, a temperature rating of 14 to 248 degrees F (-10 to 120 degrees C), a male x female connection with either 1/4" or 1/2" NPT rate, and operates under pressures up to 3,400 psi. The brass wetted parts are for use with non-corrosive liquid and gas pressure. The adjustable stainless steel needle valve restricts flow under operating conditions with variable pressure. The snubber has a nitrile rubber O-ring for a tight seal. It operates under pressures up to 3400 psi, and is effective for applications with pressures above 5 psi. The snubber measures 2.4" (6 cm) high and 1" (2.5 cm) in diameter and has a temperature rating of 14 to 248 degrees F. Pressure gauge snubbers suppress the effects of pressure pulses and pressure peaks to increase the service life of pressure gauges in harsh applications, such as on reciprocating pumps and compressors, hydraulic presses, or fluid power systems, and improve the reading accuracy of the gauge.

Pressure gauges are instruments used to measure the pressure of a gas or liquid inside a vessel and, often, to help ensure the optimal amount of pressure for a given application. Pressure gauges can range from everyday instruments, such as those used to measure the air pressure in a car or bicycle tire, to highly accurate gauges used in mechanical and industrial processing. Most often, pressure gauges measure pressure relative to another reference. For instance, gauge pressure measures pressure relative to ambient air. An example of a pressure gauge measuring relative to ambient air is a tire pressure gauge or a blood pressure gauge. Differential pressure is the difference in pressure between two points, such as when measuring liquid flow along various points in a pipeline. An absolute pressure gauge measures pressure relative to a perfect vacuum, such as an atmospheric or barometric pressure gauge. All types of pressure gauges include either a male or a female mount to connect to the vessel where pressure is being measured, and display results on a dial with varying increments of measure across a given range.

WIKA Instrument Corporation is a global manufacturer of pressure and temperature measurement instruments, including pressure gauges, diaphragm seals, pressure transmitters, and thermometers, that meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1946, is headquartered in Lawrenceville, GA.
