Compressed Air Fitting - Check Valve

Straight and reducing fittings

Some fittings are available as straight or reducing types. Straight fittings use the same diameter tubing across all ports while reducing fittings have ports of different diameters (larger or smaller) to connect tubes of different sizes.

Straight compressed air fittings connect a tube in a straight line to a male or female threaded secondary port.

Internal hexagon fittings (Hex) have a push-in port with an internal hexagon (Unbraco) socket. The inner hexagon can be tightened with an Allen key inserted in the push-in port.

Elbow fittings

Elbow fittings are available with a secondary port in both male and female threads in BSP and BSPT. Elbow compressed air fittings are often used where a smaller radius is needed than can be achieved with a tube.

Compressed air fittings 4-6 ports

Some pneumatic fittings have multiple ports, but typically no more than 6. A few examples of compressed air fittings with multiple ports are cross connectors and 5-way manifolds.
These pneumatic fittings are used for special applications where they can reduce the total amount of fittings.

Tee push-in pneumatic fittings

Tees have either three push-in ports or 2 push-in and a threaded port available in both male and female in BSP or BPST (conical) versions.

Reduction Tees are used to connect a smaller diameter tube with two larger diameter tubes.

A variant of these are the so-called run-tees or odd tees where the threaded port sits in extension of one of the push-in ports.

Y type push-in compressed air fittings form a “Y” that connects three hoses with equal diameters. Reducing Y fittings connects a larger diameter tube with two smaller diameter tubes. There are also Y-fittings with 2 push-in ports and one BSP or BSPT pipe threaded male port.

Compressed air fittings typically connect two compressed air tubes, or tubing, and an instrument or similar.

Push-to-pull, push-to-connect, push-in, push-fit fittings are available with both parallel (BSP) and conical (BSPT) threads and can be quickly installed in a leak-free seal. The tube is simply cut with a hose cutter (for example our USAG tube cutter) and inserted into the fitting, which is then ready for use.

Removal is performed by holding down the retaining ring and pulling the tube out.

Note that the tubes must be more fully inserted to ensure a correct seal. Stainless steel fittings are ideal for pharma, food, and industrial pneumatic applications that require a high degree of corrosion resistance.

NexoAir push-in fittings are available for 4 mm to 12 mm OD tubing and can be used in temperatures from -15°C to +200°C and up to 20 bar.
