Eaton 2018-4-6S Female Jic 37 Swivel Male Pipe Adapter

Product Description

The EATON 2018-4-6S is a steel flared tube adapter that connects a female JIC 37-degree swivel end to a male NPT pipe thread. It is designed for use in hydraulic, pneumatic, and fluid transfer systems where a secure, leak-resistant transition between a flared tube line and a pipe-threaded port is required. The fitting features a 3/8-inch tube outside diameter on the flare end and a 1/4-inch NPT male thread on the pipe end. Rated for service from -40 degrees F to 250 degrees F, this adapter is installed by hydraulic technicians, plumbers, and industrial maintenance professionals working with steel tubing assemblies.

This adapter is suited for residential and commercial fluid system applications where a JIC 37-degree flared tube line must terminate at a male NPT port. Typical installations include hydraulic power units, fluid control panels, compressor lines, and similar systems that use SAE J514-compliant fittings. The swivel design on the flare end allows the technician to orient the tube without twisting the line during final tightening, reducing installation stress on the tubing.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid systems requiring a JIC 37-degree swivel flare to male NPT transition on 3/8-inch OD steel tubing with a 1/4-inch NPT port.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed tradesperson familiar with SAE J514 flared fittings. Depressurize and isolate the hydraulic or fluid system fully before removing or installing any fittings. Use appropriate flare nut wrenches to avoid rounding the fitting hex; do not use pipe wrenches on the swivel body. Apply thread sealant to the male NPT threads as required by the system specifications, and inspect the flare seat for damage before assembly.
