The EATON 2018-8-8S is a steel hydraulic fitting that connects a female JIC 37-degree flared swivel end to a male NPT pipe thread. It serves as a transition adapter in hydraulic and fluid power lines where a flared tube connection must terminate at a male pipe port. The fitting accepts a 1/2-inch tube OD on the flare side and a 1/2-inch NPT thread on the pipe side. Rated to 5000 psi maximum working pressure and suitable for temperatures from -40 degrees F to 250 degrees F, this adapter is built for demanding hydraulic plumbing work. Licensed plumbers, hydraulic technicians, and fluid power mechanics are the primary installers.
This adapter is suited for use in industrial hydraulic systems, mobile equipment, and fluid power circuits where a JIC 37-degree flare tube line must connect to a male NPT port on a valve, manifold, pump, or cylinder. The swivel design on the JIC end allows the fitting to rotate during tightening, reducing stress on the connected tube. It conforms to SAE J514, making it appropriate for standard hydraulic plumbing applications in both fixed and mobile machinery.
Designed as an OEM-style hydraulic adapter for fluid power systems requiring a JIC 37-degree flare swivel to male NPT transition on 1/2-inch tube OD lines.
Installation should be performed by a qualified hydraulic technician or licensed plumber. Depressurize and drain the hydraulic system completely before removing or installing any fittings. The swivel nut on the JIC end should be tightened to a snug fit against the tube flare seat without over-torquing the flare. Inspect the flare seat and NPT threads for damage or contamination before assembly.
