Legris 0670 00 17 Pneumatic Silencer Muffler 3/8 Bspp

Product Description

The LEGRIS 0670 00 17 is a threaded silencer muffler designed to reduce exhaust noise on pneumatic systems. Manufactured from bronze, it threads directly into valve exhausts, actuator ports, or manifold exhaust ports using a 3/8 inch BSPP thread. With a decibel rating of 108 dB and a maximum flow rate of 10.5 CFM, this muffler is sized for moderate-duty pneumatic circuits. Its compact form factor — 37 millimeters overall length and 19 millimeters diameter — allows installation in tight panel or valve manifold configurations. Pneumatic technicians and industrial maintenance professionals are the typical installers.

This muffler is suited for use in compressed air systems found in industrial automation, production equipment, and general pneumatic control panels. It is appropriate for applications where exhaust noise reduction is required at directional control valves, solenoid valves, or pneumatic cylinders. The operating temperature range spans -4 degrees F to 300 degrees F, making it compatible with standard shop-air environments and lightly elevated-temperature service conditions. It is sold individually and installs without special tooling beyond a wrench.

Key Features

• 3/8 inch BSPP threaded connection for direct port installation
• Bronze construction for corrosion resistance in compressed air service
• 10.5 CFM flow capacity suitable for moderate-duty pneumatic circuits
• 108 dB rating quantifies exhaust noise attenuation performance
• Compact size: 37 millimeters length and 19 millimeters diameter
• Operating range of -4 degrees F to 300 degrees F

Compatibility

Designed as a direct-thread replacement or new-installation silencer muffler for pneumatic valves, actuators, and manifolds equipped with 3/8 inch BSPP exhaust ports.

Installation Notes

Installation is performed by pneumatic or industrial maintenance technicians. Isolate and bleed down system air pressure completely before removing or installing any exhaust port fittings. Thread the muffler into the exhaust port by hand first, then snug with a wrench — do not overtighten bronze fittings as the material is susceptible to thread damage. Verify there are no air leaks at the thread joint before returning the system to service.
