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 1/4" Tube x 3/8" NPT Female fitting? ⌄

The 1/4" Tube x 3/8" NPT Female fitting is designed to connect 1/4" airline tubing to a 3/8" NPT male threaded component. This allows for secure and efficient air transfer in air suspension systems.

What materials is this fitting made from? ⌄

This fitting is typically made from durable brass or similar materials, ensuring longevity and resistance to corrosion, which is essential for maintaining air pressure in suspension systems.

Is this fitting compatible with all air suspension systems? ⌄

While the 1/4" Tube x 3/8" NPT Female fitting is versatile, it is important to ensure compatibility with your specific air suspension setup. Always check the specifications of your system to confirm proper fitment.

What are the typical applications for this fitting? ⌄

This fitting is commonly used in air suspension systems for vehicles, trailers, and caravans, where it connects air lines to valves, compressors, or tanks, facilitating efficient air management.

How do I ensure a leak-free connection with this fitting? ⌄

To achieve a leak-free connection, it is recommended to use a liquid thread sealant on the NPT threads rather than thread tape. Ensure that the fitting is tightened securely without over-tightening, which can damage the threads.

Can this fitting be used with different tube sizes? ⌄

No, this fitting is specifically designed for 1/4" airline tubing. Using a different tube size may result in leaks or improper fitment. Always use the correct size for optimal performance.
