Applications
Use to land a -12 JIC 37° flare tube line into a 3/4 in. female NPT port:
- Hydraulic pump, motor, valve body, manifold, or cylinder ports on heavy-duty trucks and mobile equipment
- Reservoir tank and filter ports on dump bodies, wet kits, lift gates, and snow / spreader hydraulics
- Industrial fluid-power circuits transitioning between JIC tubing and NPT pipe
Use thread sealant rated for the working fluid on the NPT end. Verify both thread sizes before installation.
