Pneumatic Push In Air Fittings – Union Tee

$3.03 Inc. GST

This three-way thermoplastic union tee push-in fitting splits or combines compressed air and vacuum supply lines in a T-configuration without requiring assembly tools. Equipped with an internal O-ring seal and locking collar, the component operates within a pressure range of 0 to 10 bar and temperatures from -20°C to +60°C across 6mm and 8mm outer diameter pneumatic tubing. Primary applications include vacuum clamping tables, CNC machining setups, automated assembly networks, and industrial pneumatic control panels where tool-free line branching and fluid routing are required.

Description

Technical Overview

This union tee push-in fitting is a three-way tube-to-tube connector designed to branch airline circuits in pneumatic and vacuum distribution systems . Featuring quick-fit push-in ports across all three connections, the component enables tool-free attachment and removal of pneumatic tubing while maintaining an airtight seal under operating pressure. The fitting distributes incoming air or vacuum supply from a single source line to two separate outlet lines in a T-configuration .

Constructed from thermoplastic with an integrated internal O-ring seal and locking collar, the fitting operates within a working pressure range of 0 to 10 bar and a temperature range of -20°C to +60°C. It accommodates 6mm and 8mm outer diameter pneumatic tubing to facilitate modular fluid routing across automated machinery and clamping fixtures.

Applications

Technicians install this union tee push-in fitting in vacuum clamping tables, CNC machining setups, and automated assembly networks. In vacuum clamping applications, the fitting splits main vacuum lines to supply multiple clamping modules simultaneously from a single vacuum source.

Additionally, engineering teams integrate these fittings into industrial air distribution networks, pneumatic control panels, and prototype laboratory setups. The push-fit mechanism enables quick circuit modifications during system maintenance or machine reconfiguration.

Maker Store Tips and Tricks

Cut pneumatic tubing perpendicularly with a dedicated tube cutter to ensure a flat end face for proper O-ring engagement .
Fully insert the tubing into the fitting until it seats against the internal shoulder before testing circuit pressure .
Press the release collar evenly against the fitting body when pulling tubing out during circuit disassemblies
