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 FIT-PC3/8-N4UT air fitting is designed to create a secure and efficient connection in your air suspension system. It features a 3/8 tube to 1/2 NPT configuration, making it ideal for use with Boss airbag systems and Load Assist kits.

While the FIT-PC3/8-N4UT is optimised for Boss Air Suspension products, it can be used with other brands that have compatible 3/8 tube and 1/2 NPT fittings. However, ensure compatibility with your specific system to avoid any issues.

The FIT-PC3/8-N4UT is constructed from high-quality materials designed for durability and resistance to corrosion. This ensures long-lasting performance in demanding air suspension applications.

The FIT-PC3/8-N4UT is typically used in air suspension systems to connect air lines to airbags and other components. It is essential for enhancing load-carrying capacity and stability, particularly in Load Assist setups.
