Push-in fittings: Easy and practical solution for pipe and hose connections 

Stainless push-in fittings are a type of coupling used in the process industry to connect pipes and hoses with each other. Their popularity is due to their ease and speed of installation, as well as their high resistance to corrosion and rust, making them suitable for use in industrial environments.  

Push-in fittings consist of a moulded unit fitted with an O-ring that ensures a tight connection to the hose. The fitting is designed to couple with the hose without the use of tools, making it easy to install. Push-in fittings are available in a variety of sizes, materials and configurations to suit a wide range of applications including water, air, gas and other media.  

Alfotech offers a selection of stainless steel push-in fittings, each equipped with a corresponding gasket, to ensure maximum fastening efficacy and mitigate any potential leakage concerns. This is especially important when securing air hoses, which are primarily used in conjunction with push-in fittings. To ensure the right match between air hose and fitting, a high quality resistant Teflon hose is the right choice. 

Installation and dismantling 

Installation of stainless push-in fittings is quick and easy as it requires minimal tools and no welding or bending skills. The hose end is first cut to create a straight, uncompressed edge, after which it is inserted into the fitting until a discernible click is felt, signifying the engagement of an internal O-ring that securely locks the hose in place. This approach allows hoses to be connected and disconnected quickly and easily without having to disassemble or damage the hose or fitting. 

To remove a hose from a push-in fitting, first push the release ring inwards to release the locking mechanism. Then you can pull the hose away from the fitting. It is important to be careful when removing the hose, as it can be dangerous if the hose is under pressure. Be sure to shut off or disconnect any liquid or gas flow before removing the hose to avoid injury or accidents. 

Types and application 

Push-in fittings can be connected to pipes or hoses by "pushing" them into a push-in port. Push-in fittings have at least one push-in port and are available in a number of variants, including angled, straight and reducing fittings with various thread types. 

Push-in T-fittings 
A Push-in T-union connects three tubes of the same diameter via a cross-shaped construction. T-fittings with reduction allow the connection of hoses with different diameters. There are also T-fittings with a mix of push-in and thread, where two of the ports are push-in and one is threaded. Push-in T-fittings are a reliable and simple solution for connecting three hoses with the same or different diameters. 

Straight and reducing push-in fittings 
Straight fittings have the same diameter on all ports and are suitable for coupling hoses of the same size. Reducing fittings have varying port diameters and allow coupling of hoses of different sizes. This can be useful when reducing or increasing hose size during installation. 

Push-in angle fittings 
Angle fittings are specially designed to connect the hose at a 90-degree elbow. It is an ideal solution when there is insufficient space to bend the hose. Alfotech offers a Push-in elbow with dual hose connections, as well as a Push-in elbow with swivel and BSPP threads on one of its ports.
