Overview
The NOSHOK 1325 pressure snubber is a self-cleaning, piston-type brass instrument designed to dampen pressure fluctuations and protect pressure gauges and transducers. Engineered for industrial measurement applications, the 1325 resists clogging and delivers reliable snubbing action across a wide range of fluids and operating conditions. Its 6,000 psi maximum pressure rating and 1/4″ NPT process connection make it ideal for hydraulic, pneumatic, and utility pressure circuits.
Key Features
- Self-cleaning piston design — resists clogging and minimizes maintenance
- Five interchangeable pistons included: grades A–E for gases, water, light oil, and heavy oil applications
- Brass construction — durable and corrosion-resistant for industrial environments
- 1/4″ NPT connections — male process port, female instrument port for standard gauge mounting
- 6,000 psi rated — handles high-pressure measurement circuits reliably
