20mm Metal Air Compressor Muffler Iron Shell Intake Silencer Replacement

This 20mm metal silencer is stamped from thick cold-rolled iron plate, far tougher than plastic versions against impact, pressure and long-term vibration deformation. Full anti-rust baking paint protects the shell from rust under damp and outdoor conditions. High-density inner cotton absorbs intake noise and filters grit to prevent cylinder and piston abrasion. Standard 20mm male thread screws tightly onto most air pump intakes without air leakage. The side outlet supports flexible pipeline layout. It is universally compatible with portable compressors, inflators and small gasoline engines with plug-and-play installation. Perfect for maintenance in dusty auto repair workshops, outdoor service and factory working environments.
