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.

Is this airline suitable for use with all Boss Air Suspension products? ⌄

Yes, the 1/4" DOT Approved Black Airline is compatible with all Boss Air Suspension products that require 1/4" airline, ensuring reliable performance and durability.

How is the 1/4" DOT Approved Black Airline different from other airlines? ⌄

This airline is DOT approved and meets SAE J844 standards, ensuring it is designed for safety and reliability in air brake systems, unlike some non-approved alternatives that may not meet these rigorous standards.

Can this airline be used for both air suspension and air tools? ⌄

While the 1/4" DOT Approved Black Airline is primarily designed for air suspension systems, it can also be used for low-pressure air tools, provided the pressure does not exceed 400psi.

What should I consider when cutting this airline to length? ⌄

When cutting the 1/4" DOT Approved Black Airline, ensure you make a square cut and use a proper airline cutter to prevent angled cuts, which can lead to leaks when connecting to fittings.

How is this airline sold and what is the minimum order length? ⌄

The 1/4" DOT Approved Black Airline is sold per metre, allowing you to purchase the exact length needed for your installation without excess waste.
