Coilhose Pneumatics RK112 Hose Swivel 3/8 Inch Nylon

Product Description

The COILHOSE PNEUMATICS RK112 is a nylon hose swivel designed for use with 3/8-inch inner diameter pneumatic hose and 3/8-inch threaded fittings. The swivel joint allows the hose to rotate freely at the connection point, reducing hose twist, kink, and fatigue during operation. This fitting is a practical maintenance or repair component in compressed air distribution systems found in industrial, automotive, and general shop environments. Its nylon construction keeps weight low while offering adequate resistance to typical shop air pressures and common lubricants. Pneumatic technicians and mechanics install this type of swivel as part of routine hose assembly upkeep.

The RK112 swivel is suited for pneumatic hose assemblies in light to medium-duty compressed air systems. It is appropriate for shop air lines, tool drops, and retractable hose reel connections where hose rotation at the coupling point is needed to prevent premature hose wear. The nylon body makes it a viable option in environments where metal fittings may corrode or where weight savings are a priority. This fitting is typically used in residential garage setups, commercial automotive shops, and general maintenance facilities.

Installation Notes

Depressurize the air line completely before removing or installing any pneumatic fitting. Use appropriate thread sealant if required by the application and verify thread type before installation to ensure proper engagement. Hand-tighten first, then use a wrench to snug the fitting without overtightening nylon components, as excessive torque can crack the body. Installation is typically performed by a pneumatic technician or qualified maintenance professional.
