Frequently asked questions

Should I use thread tape or thread sealant on air fittings?

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.

How do I avoid leaks with push-to-connect fittings?

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.

Can I reuse push-to-connect fittings and airlines?

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.

What is the purpose of the 3/8TUBE x 1/4NPT FEMALE fitting?

The 3/8TUBE x 1/4NPT FEMALE fitting is designed to connect a 3/8 inch air line to a 1/4 inch NPT female thread. It ensures a secure and efficient connection in your air suspension system, which is crucial for maintaining optimal performance.

What applications is this fitting suitable for?

This fitting is ideal for use in air suspension systems, particularly in load assist kits. It is commonly used to connect airbags to the air supply, providing necessary support and stability for vehicles under load.

What materials is this fitting made from?

This fitting is constructed from high-quality materials to ensure durability and resistance to wear. It is designed to withstand the pressures typically encountered in air suspension systems, providing a reliable connection.

How do I install the 3/8TUBE x 1/4NPT FEMALE fitting?

To install the fitting, ensure that the 3/8 inch tubing is cut squarely and fully inserted into the fitting. Use a liquid thread sealant on the NPT threads to prevent leaks. Tighten securely, but avoid over-tightening to prevent damage.

What are the key differences between this fitting and other sizes?

The 3/8TUBE x 1/4NPT FEMALE fitting is specifically designed for applications requiring a 3/8 inch tube connection to a 1/4 inch NPT thread. Other sizes may not fit correctly and could lead to leaks or system failures, so it's important to use the correct fitting for your specific setup.
