Coilhose Pneumatics PSM0304 Male Swivel Hose Fitting 1/4 Npt

Product Description

The COILHOSE PNEUMATICS PSM0304 is a brass reusable male swivel hose fitting designed for pneumatic hose assemblies. It connects air hose to threaded ports using a 1/4 NPT male thread while allowing the hose to swivel freely, reducing kinking and twisting during operation. The fitting is sized for hose with a 3/16 inch inner diameter and a 5/16 inch outer diameter. Constructed from brass, it resists corrosion and handles the pressures common in shop air and light industrial pneumatic systems. Reusable design means the fitting can be removed and reinstalled without destroying the hose end, making it a practical choice for service and maintenance work.

This fitting is suited for residential and commercial pneumatic applications where a reliable, low-profile hose termination is needed. Typical uses include air tool lines, compressor hose assemblies, and shop air distribution setups. The male swivel configuration is especially useful in tight or awkward routing situations where a fixed fitting would cause hose stress. Installation is handled by HVAC technicians, plumbers, mechanics, and general tradespeople who maintain or build pneumatic hose assemblies.

Key Features

• Reusable design allows fitting removal and reinstallation without damaging the hose
• Swivel action reduces hose kinking and twisting at the connection point
• 1/4 NPT male thread for standard pneumatic port compatibility
• Sized for 3/16 inch ID x 5/16 inch OD hose
• Brass construction for corrosion resistance in compressed air service

Compatibility

Designed as a reusable field-serviceable fitting for pneumatic hose with a 3/16 inch inner diameter and 5/16 inch outer diameter, connecting to 1/4 NPT threaded ports in compressed air systems.

Installation Notes

Installation is typically performed by qualified tradespeople familiar with pneumatic hose assemblies. Depressurize and bleed the air line completely before removing or installing any fitting. Apply thread sealant or PTFE tape to the NPT male threads per standard practice for compressed air connections. Inspect the hose end for cuts or deformation before reusing the fitting to ensure a leak-free seal.
