Air Fittings Push In

Quality air systems are built on secure fittings. Push in air fittings are an easy way to connect nylon air lines across truck and trailer air systems safely and quickly. Reliable push to connect air fittings maintain consistent airflow and make repairs and servicing quicker in the workshop. At MaxiPARTS we have a full range of brass pneumatic push in air fittings, from adaptors, elbows, joiners and tee pieces in BSP, NPT and metric sizes to suit heavy vehicle applications across Australia.

Types of push in air fittings available

Different air systems need different fitting styles. MaxiPARTS stocks a broad range of push in air fittings suited to air brake systems, suspension lines, and general compressed air plumbing.

Push in adaptors

Push in adaptors are used to connect different thread types or tube sizes. They are commonly fitted when replacing valves, tanks, or existing air line components.

Push in elbows

Elbows allow air lines to change direction without kinking the hose. They are useful in tighter spaces where straight fittings may not suit the layout.

Push in joiners

Joiners connect two sections of air line together. They are often used when extending or repairing damaged sections of tubing.

Push in tee pieces

Tee pieces split one air line into multiple directions. These fittings are commonly used across suspension systems and auxiliary air circuits.

BSP, NPT and metric: choosing the right thread and size

Getting the correct thread and tube size matters. Matching fittings properly helps prevent leaks and keeps the system working the way it should.

Fractional sizes: 1/8", 1/4", 3/8", 1/2"

Fractional fittings are common across many truck and trailer air systems. Always check the existing fitting size before replacing components.

Metric sizes: 4mm, 6mm, 8mm, 10mm

Metric air lines are widely used across modern heavy vehicles. Matching the tube diameter correctly helps maintain a proper seal and reliable airflow.

Why use push in air fittings?

Push to connect air fittings speed installation and make service work easier. Technicians can push air lines in and out without using special tools.

A good pneumatic push in air fitting will also help to prevent air leaks caused by poor connections or worn out fittings. Brass fittings are popular because they can handle vibration, pressure, and shop conditions.

Push in air fittings help workshops and fleet operators keep trucks rolling and minimise downtime for service and repair.

Choosing the right push in air fitting

A few simple checks can help you choose the right fitting.

• Match the fitting size to the existing air line diameter

• Check whether the thread is BSP or NPT

• Use joiners for extending lines and elbows for tighter bends

• Choose tee pieces when splitting air lines

• Confirm the fitting suits air brake or suspension systems

All fittings on this page are brass and designed for standard truck and trailer air system pressures.

Installation and maintenance tips

Good installation helps prevent future air leaks.

• Cut air line tubing cleanly before fitting

• Push tubing fully into the fitting

• Inspect fittings during routine servicing

• Replace cracked or damaged fittings early

• Check air lines for leaks after installation

Regular checks help keep truck and trailer air systems reliable.
