Steel 37° JIC Female Swivel x Female NPT Hydraulic Adapter
The Steel 37° JIC Female Swivel x Female NPT Adapter is a straight connector that joins a 37° JIC (SAE J514) flare line to a female NPT pipe port. The live swivel nut on the JIC side lets you tighten the connection to a sealed, leak-free joint without twisting or kinking the hose or tube — making installation and service fast in tight spaces.
Machined from carbon steel for high-pressure hydraulic and pneumatic service, this adapter is a workhorse fitting for air compressor plumbing, hydraulic power units, and fluid-transfer lines.
