Legris 0670 00 34 Threaded Silencer Muffler 1 in Bspp

Product Description

The LEGRIS 0670 00 34 is a threaded silencer muffler designed to reduce exhaust noise in pneumatic systems. Manufactured from bronze, this muffler threads directly into exhaust ports on pneumatic valves, cylinders, and actuators to attenuate air discharge noise. It carries a maximum flow rate of 13 CFM and a decibel rating of 128 dB, making it suitable for compressed-air circuits operating within a temperature range of -4 degrees F to 300 degrees F. The 1-inch BSPP thread provides a standard connection for metric and British-standard pneumatic components. Installation requires no special tooling beyond a wrench and basic thread sealant.

This muffler is used in industrial and commercial pneumatic systems wherever directional control valves, solenoid valves, or actuators vent exhaust air to atmosphere. Typical applications include compressed-air distribution panels, automated assembly equipment, and pneumatic control circuits requiring noise management at exhaust ports. The bronze construction resists corrosion in environments where moisture or mild contaminants may be present in the exhaust stream. It is well suited for both OEM panel builds and field service replacement on existing pneumatic installations.

Key Features

• 1-inch BSPP threaded connection for direct installation into valve exhaust ports
• Bronze construction provides corrosion resistance in pneumatic exhaust environments
• 13 CFM maximum flow rate supports standard-duty pneumatic valve exhaust
• Operating temperature range of -4 degrees F to 300 degrees F
• 60 mm overall length and 36 mm overall diameter for compact installation clearance

Compatibility

Designed as an OEM-style replacement or new-installation muffler for pneumatic valves and actuators with 1-inch BSPP exhaust port threads.

Installation Notes

Pneumatic silencer mufflers are installed by qualified pneumatic system technicians or industrial maintenance personnel. Depressurize and lock out the compressed-air supply before servicing any exhaust port fitting. Apply appropriate thread sealant per the system manufacturer's guidelines and tighten to hand-tight plus a controlled additional turn to avoid over-torquing the bronze body. Verify there are no air leaks at the thread joint before returning the system to service.
