Coilhose Pneumatics PSM0404 Brass Male Swivel Fitting

Product Description

The COILHOSE PNEUMATICS PSM0404 is a brass reusable male swivel hose fitting designed for pneumatic hose connections in compressed air systems. It features a 1/4-inch NPT threaded end and accepts hose with a 1/4-inch inner diameter and 3/8-inch outer diameter. The swivel design allows the fitting to rotate freely during installation and operation, reducing hose twist and stress at the connection point. Constructed from brass, this fitting resists corrosion and holds up in demanding shop and industrial environments. It is sold individually and is appropriate for use by HVAC technicians, plumbers, and pneumatic system installers who need a reliable, reusable field fitting.

This fitting is suited for use in residential and commercial compressed air distribution, pneumatic tool lines, and general industrial hose assemblies. The male NPT thread connects to standard female NPT ports on compressors, manifolds, regulators, and other pneumatic components. The reusable design means the fitting can be removed and reinstalled without replacing the hose end, making it a practical choice for service applications where hose assemblies are frequently reconfigured.

Key Features

• Brass construction for corrosion resistance in compressed air service
• Reusable design allows multiple installations on the same hose
• Male swivel allows free rotation to prevent hose twist during connection
• 1/4-inch NPT thread fits standard female NPT pneumatic ports
• Accepts 1/4-inch ID x 3/8-inch OD hose
• Threaded connection type for secure, leak-resistant assembly

Compatibility

Designed as an OEM-style replacement or field fitting for pneumatic hose assemblies using 1/4-inch ID by 3/8-inch OD hose with 1/4-inch NPT threaded ports.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or pneumatic system mechanics. Depressurize and bleed the air line completely before disconnecting or installing any hose fitting. Apply thread sealant or PTFE tape to NPT threads per standard practice before making up the connection. Tighten to hand-tight plus a moderate number of turns — do not overtighten brass NPT fittings, as this can crack the fitting body.
