Coilhose Pneumatics LMM0404S Swivel Fitting 1/4 in Npt

Product Description

The COILHOSE PNEUMATICS LMM0404S is a brass pneumatic swivel fitting designed for use in compressed air systems where rotational movement at the connection point is required. The swivel design allows hoses and tools to rotate freely without twisting or kinking the air line, maintaining consistent airflow during operation. Featuring a 1/4 inch male NPT thread and an 11/16 inch body diameter with a nickel finish, this fitting is rated for working pressures up to 150 psi. It is a threaded connection type suited for direct installation into compatible pneumatic ports and hose assemblies. Licensed professionals and experienced technicians handling compressed air distribution typically install this type of fitting.

This swivel fitting is used in industrial, commercial, and shop pneumatic systems where air tools, blow guns, or hose assemblies require freedom of movement at the point of connection. The 1/4 inch NPT thread size is a common standard in light- to medium-duty pneumatic plumbing, making this fitting widely applicable in maintenance, manufacturing, and general-purpose air tool setups. The brass construction with nickel finish provides durability and resistance to corrosion in typical shop environments.

Compatibility

Designed as an OEM-style replacement or addition for pneumatic systems using 1/4 inch male NPT threaded fittings with a maximum working pressure of 150 psi.

Installation Notes

Installation is typically performed by a pipefitter, pneumatic technician, or experienced maintenance professional. Depressurize and lock out the air supply before servicing any pneumatic connection. Apply thread sealant tape appropriate for pneumatic service to the male NPT threads before installation. Tighten to hand-snug plus appropriate wrench turns per standard NPT fitting practice — do not overtighten, as brass fittings are subject to thread damage under excessive torque.
