Coilhose Pneumatics CSM0504 Hose Swivel 5/16 in Id

Product Description

The COILHOSE PNEUMATICS CSM0504 is a nylon hose swivel mender designed to connect and maintain flexibility between sections of pneumatic hose. The swivel design allows the hose to rotate freely at the connection point, reducing kinking, twisting, and premature hose wear during use. Built from nylon construction, this fitting is lightweight and resistant to common shop fluids and moderate abrasion. It accepts a 5/16 inch inner diameter hose and features a 1/4 inch thread for a secure, leak-resistant connection. Pneumatic technicians and maintenance professionals working with compressed air systems rely on swivel fittings like this to keep hose runs tidy and functional in demanding shop or field environments.

This swivel mender is suited for use in compressed air distribution systems found in automotive shops, manufacturing facilities, and general industrial maintenance settings. It is typically installed inline where hose movement or rotation is expected, such as near reels, at tool connections, or along routing paths that experience regular repositioning. The nylon material makes it appropriate for dry or lightly lubricated air lines operating within standard shop pressure ranges.

Key Features

• Swivel design allows free hose rotation to reduce kinking and twisting
• Nylon construction offers lightweight durability and fluid resistance
• 5/16 inch inner diameter hose compatibility

Compatibility

Designed as an OEM-style replacement or service fitting for pneumatic air hose assemblies requiring a 5/16 inch ID swivel mender with 1/4 inch thread.

Installation Notes

Installation should be performed by a qualified pneumatic technician or maintenance professional. Depressurize and bleed the air line completely before removing any existing fittings or installing this swivel mender. Hand-tighten the threaded connection first, then snug with appropriate wrenches — avoid overtightening nylon fittings, as excess torque can crack the body. Verify the connection is leak-free by pressurizing the system and checking with soapy water or a leak detector before returning to service.
