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 PL 4mm tube to M5 fitting? ⌄

The PL 4mm tube to M5 fitting is designed to connect 4mm airline tubing to M5 metric threaded components. This allows for a secure and leak-free connection in air suspension systems.

Is this fitting suitable for high-pressure applications? ⌄

Yes, the PL 4mm tube to M5 fitting is suitable for high-pressure applications within the limits of the airline and air suspension system. Always ensure that the entire system is rated for the required pressure.

What materials are used in the construction of this fitting? ⌄

The PL 4mm tube to M5 fitting is typically made from durable plastic or brass, ensuring longevity and resistance to corrosion. This makes it suitable for various environmental conditions.

What are the typical applications for this fitting? ⌄

This fitting is commonly used in air suspension systems for connecting airlines to valves, compressors, and airbags. It is ideal for applications requiring a compact and reliable connection.
