Product details
Weiss Pressure Snubber | PSNS25 | 1/4″ NPT | 303 Stainless Steel
Product Description
The PSNS25 acts as a protective dampener between the process line and the pressure gauge. The “PSNS” designation identifies this as a Stainless Steel snubber, while the “25” denotes the standard 1/4″ NPT connection size used in most commercial and industrial gauge installations.
In the UAE’s mechanical sector, equipment such as booster pumps and rapid-acting solenoid valves can create massive pressure spikes, also known as “fluid hammer.” These spikes cause the gauge needle to vibrate uncontrollably (pointer flutter) and can lead to permanent internal mechanical fatigue. The PSNS25 utilizes a micro-porous sintered metal filter to restrict the flow of fluid, “smoothing” the pressure wave so the gauge provides a steady, accurate reading. The use of 303 Stainless Steel ensures the snubber can handle corrosive fluids and high-temperature environments where brass models would be unsuitable.
Key Features
- 303 Stainless Steel Construction: Provides superior strength and excellent resistance to corrosion, making it suitable for treated water, steam, and industrial chemicals.
- Precision Pulsation Dampening: Eliminates pointer flutter and protects the internal Bourdon tube from mechanical fatigue and shock.
- Micro-Porous Filter Element: Features a high-quality sintered metal disc that restricts rapid pressure changes while allowing accurate static pressure monitoring.
- 1/4″ NPT Standard Connection: Features a male-to-female configuration (1/4″ MNPT x 1/4″ FNPT) for direct installation between the process pipe and the gauge.
- Wide Temperature Range: Specifically designed to handle the high-heat requirements of steam and industrial process lines in the Middle East.

Frequently Asked Questions
- Q: When should I use the Stainless Steel (PSNS25) over the Brass (PSNB25) model?
- A: Use the stainless steel model for steam, corrosive fluids, or where the system pressure exceeds 3,000 PSI. It is also preferred in coastal UAE areas where the air is highly saline and could corrode brass components.
- Q: Can this be used for compressed air?
- A: Yes, it is excellent for dampening the pulsations from reciprocating air compressors which can cause gauges to wear out prematurely.
- Q: Does it affect the accuracy of the gauge?
- A: It slows down the time it takes for the gauge to reach the current pressure reading by a fraction of a second, but it does not change the final pressure value displayed.
