Eaton 2018-8-10S Female Jic 37 to Male Npt Adapter 5/8 in

Product Description

The EATON 2018-8-10S is a steel flared tube adapter that connects a female JIC 37-degree swivel end to a male NPT pipe thread. It is used in hydraulic and fluid-power plumbing lines where a flared tube fitting must transition to a standard pipe thread port. The swivel design on the JIC end allows the fitting to rotate during installation, reducing tube twist and making alignment easier in tight spaces. Rated for service from -40 degrees F to 250 degrees F and conforming to SAE J514, this adapter suits hydraulic, pneumatic, and fluid-transfer systems. It weighs 0.23 pounds and measures 2.12 inches in overall length. Installation is performed by licensed pipefitters, hydraulic technicians, or qualified mechanical tradespeople.

This adapter is appropriate for residential, commercial, and industrial fluid-power applications wherever a 5/8-inch OD flared tube line must connect to a 1/2-inch NPT male pipe port. Typical install scenarios include hydraulic manifolds, power-unit plumbing, lubrication systems, and compressed-air distribution lines. The NPTF-compatible thread seals under pressure without relying solely on thread sealant, though thread compound or PTFE tape is standard practice. The fitting is sold individually and is stocked as a single-piece unit.

Key Features

• Female JIC 37-degree swivel inlet accepts 5/8-inch OD flared tube
• Male NPT outlet threads directly into standard pipe ports
• Swivel end reduces tube twist during tightening
• Rated from -40 degrees F to 250 degrees F
• Conforms to SAE J514 flared-tube fitting standard
• Steel construction for durability in hydraulic and fluid-transfer service

Compatibility

Designed as a standard SAE J514-compliant adapter for hydraulic and fluid-power systems using 5/8-inch OD flared tube lines with a 1/2-inch NPT male pipe connection port.

Installation Notes

Shut down system pressure and depressurize all lines before removing or installing any hydraulic fitting. Apply thread sealant or PTFE tape to the male NPT threads in accordance with system requirements and applicable codes. Tighten the NPT end to the port first, then snug the JIC swivel nut against the flared tube seat — do not overtighten the flare seat, as this can damage the sealing surface. Work performed on pressurized fluid systems should conform to relevant industry and facility safety standards.
