3/8 Tube x 1/4 NPT 90 Degree Male

Boss recommends using a liquid thread sealant rather than thread tape. Small fragments of thread tape can break off, travel through the airlines and lodge in valves or valve blocks, causing them to stick open or closed. A quality thread sealant seals the threads without shedding debris.

Always cut the airline square with a sharp tube cutter, not side cutters. Push the tube firmly into the fitting until it bottoms out, then pull back gently to seat the collet. Most leaks are caused by angled cuts, scratched tube, or the line not being fully inserted.

You can often reuse fittings and lines if they are in good condition, but if the tube end is scratched, oval or has been repeatedly removed, it is safer to cut back to a fresh section or replace it. Damaged tube ends are a common source of slow leaks.

The 3/8 Tube 1/4NPT 90 Degree fitting is designed to connect 3/8" airline tubing to a 1/4" NPT male thread. It allows for a smooth and secure transition between the airline and the threaded component, ensuring efficient air flow in your air suspension system.

This fitting is typically used in air suspension systems, particularly for connecting air lines to compressors, tanks, or valves. Its 90-degree elbow design is ideal for tight spaces where a straight fitting may not fit properly.

The 3/8 Tube 1/4NPT 90 Degree fitting is specifically designed for use with 3/8" push-to-connect airline tubing. Ensure that the tubing is compatible with push fittings to guarantee a secure and leak-free connection.

To install the fitting, simply cut the 3/8" airline tubing squarely and push it into the fitting until it is fully seated. Then, thread the 1/4" NPT male end into your desired component, ensuring to use a liquid thread sealant to prevent leaks.

The 90-degree design of this fitting allows for more flexible routing of air lines, especially in confined spaces. It helps to minimise strain on the tubing and reduces the risk of kinks or bends that could impede airflow.
