About Union tees

A push-in T-connector branches a compressed air line or brings two lines together. The tube is pushed in without tools and released again through the release ring. The range covers tube outside diameters from 3 to 16 mm and working pressures up to 20 bar.

What matters when choosing

• Tube outside diameter from 3 to 16 mm. The size has to match the tube exactly, otherwise the collet will not hold reliably.
• Series: Blue Series, Blue Series mini, click-clock, metallica, NonPlusUltra and inox line are available. The series fixes the design and the material, so it pays to stay with one series across an installation.
• Material: plastic with nickel-plated brass, all nickel-plated brass, or stainless steel 1.4404 for corrosive surroundings.
• Seal material: NBR for ordinary compressed air, FKM, FPM at higher temperatures and in the FDA-compliant version where that approval is required.
• Pressure range: versions reach 10 to 20 bar working pressure and operate down to -0.99 bar, so they also suit vacuum lines.

Typical applications

• Branching control air to a second cylinder or valve inside a machine.
• Distributing compressed air in handling and assembly cells built with plastic tube or plastic pipe.
• Vacuum lines on suction grippers, since the connectors are rated down to -0.99 bar.
• Installations exposed to moisture or cleaning agents, using the stainless steel 1.4404 version.
• Small-bore lines carrying neutral gases and liquids as well as oil and grease.

Materials run from plastic with nickel-plated brass through all nickel-plated brass to stainless steel 1.4404, with NBR and FKM, FPM seals, the latter also in an FDA-compliant version. Operating and medium temperature are stated as -20 °C to 150 °C.
