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 Equal Union Straight fitting is designed to connect two 3/8 push fit lines securely. It is ideal for creating efficient joins in air suspension systems, ensuring reliable air flow between components.

This fitting is commonly used in air suspension setups for vehicles, trailers, and caravans. It helps maintain consistent air pressure and flow, which is essential for optimal suspension performance and stability.

The 3/8 Equal Union Straight is specifically designed for equal connections, allowing for a straight join between two lines. Unlike other fittings that may have different diameters or angles, this fitting ensures a direct and efficient connection.

The 3/8 Equal Union Straight is designed to handle standard air pressures used in air suspension systems. Always refer to the specific guidelines for your system to ensure compatibility and safety.
