Glacier Diesel Power 1/2" MPT x -6 MJIC Adapter Fitting | Steel Pipe to JIC Adapter
Description
Building a reliable custom fluid system starts with using the correct adapters.
The Glacier Diesel Power 1/2" MPT x -6 MJIC Adapter provides a simple and dependable way to convert a 1/2-inch male pipe thread (MPT/NPT) connection into a -6 JIC (37° flare) connection. Whether you're plumbing a custom fuel system, transmission cooler, oil system, coolant circuit, or air system, this adapter creates a secure transition between traditional pipe threads and industry-standard JIC fittings.
Designed for builders who demand reliability, this adapter makes it easy to connect reusable -6AN/JIC hose assemblies to components equipped with 1/2-inch pipe threaded ports. Its compact straight design allows for clean routing while maintaining excellent sealing and long-term durability.
Whether you're fabricating a complete system or replacing an existing fitting, this adapter delivers the dependable connection professional builders expect.
Features
- Converts 1/2" Male Pipe Thread (MPT/NPT) to -6 Male JIC (37° flare)
- Durable steel construction
- Precision-machined sealing surfaces
- Straight adapter design
- Compatible with standard -6 JIC and -6AN hose ends
- Suitable for fuel, oil, coolant, hydraulic, transmission, and air systems
- Corrosion-resistant finish
Why Convert to JIC / AN Fittings?
Modern performance plumbing is built around AN and JIC-style fittings because they offer exceptional sealing, easy serviceability, and long-term reliability.
Unlike pipe threads, which seal on the threads themselves, JIC fittings use a 37-degree flare seat to create a positive mechanical seal. This allows hose assemblies to be disconnected and reused repeatedly without relying on thread sealant at the hose connection.
By converting threaded ports to JIC fittings, custom plumbing becomes easier to service, easier to route, and more reliable over the life of the vehicle.
