Dwyer PS222 Stainless Steel Pressure Snubber 1/4" NPT Water & Oil Service

The Dwyer Instruments PS222 is a stainless steel pressure snubber designed for water and oil service applications. Part of Dwyer's Series PS lineup, this snubber protects pressure gauges and instrumentation by dampening pressure surges and pulsations, ensuring steady, accurate average pressure readings and extending instrument service life.

Constructed with a corrosion-resistant stainless steel body and AISI 316 SS filter disc, the PS222 is well-suited for demanding liquid and oil environments where brass hardware would be insufficient. The sintered filter disc restricts rapid pressure spikes while allowing the instrument to track true average system pressure.

Key Features:

• Service Type: Water and oil service
• Connection Size: 1/4" NPT male x female (inline installation)
• Body Material: Stainless steel
• Filter Disc Material: AISI 316 stainless steel
