Description
Superlok OD to MJIC Adapter - SAU - Various Sizes - 1/4", 3/8", 1/2" | USA Lab
The Superlok OD to MJIC Adapter (SAU series) provides a reliable transition from Superlok double-ferrule tube connections to standard male JIC (MJIC) 37° flare fittings. Built from high-quality 316 stainless steel, these adapters help you connect tubing runs to valves, manifolds, hoses, and instrumentation ports with leak-tight, vibration-resistant performance.
Designed for demanding hydraulic, pneumatic, and process control applications, Superlok OD to MJIC Adapters are available in popular tube sizes — 1/4", 3/8", and 1/2" OD. Each fitting is precision machined, fully gauged, and engineered for consistent make-up, making them ideal for lab skids, pilot plants, industrial OEM systems, and field service work.
When paired with Superlok tube fittings, the SAU adapter helps maintain system integrity under high pressure and thermal cycling, while the MJIC male connection lets you integrate with standard hose ends and JIC ports commonly found across industrial and laboratory equipment.
Please note: Fittings that have been installed, pressurized, or show signs of use may not be eligible for return. Confirm sizing, material compatibility, and pressure requirements before placing your order.

FAQ
What is a Superlok OD to MJIC adapter?
The Superlok OD to MJIC Adapter - SAU - Various Sizes - 1/4", 3/8", 1/2" is a precision 316 stainless steel fitting that converts a Superlok double-ferrule OD tube connection to a male JIC (MJIC) 37° flare connection. It lets you transition cleanly from rigid tubing to standard JIC ports commonly used on hoses, valves, and hydraulic components.
What sizes are available for this fitting?
These adapters are offered in popular tube outer diameters — 1/4", 3/8", and 1/2" OD. Each SAU model pairs the corresponding Superlok tube size with a matching MJIC size, making it easy to select a fitting that matches your tubing and JIC port.
What pressure can Superlok OD to MJIC Adapters handle?
Superlok fittings are designed for high-pressure service when installed correctly and used with compatible tubing. Actual pressure ratings depend on the fitting size, tubing material, and wall thickness. Always consult the Superlok pressure rating charts and your system requirements before operation.
Can I reuse these adapters after disassembly?
In many cases, Superlok OD to MJIC Adapters can be re-made if the ferrules, body, and 37° flare seating surfaces are clean and undamaged. However, you should always inspect components carefully, follow manufacturer instructions, and avoid reusing fittings in critical service if there are any signs of wear or galling.
