About Y unions

Push-in Y-connectors split one line into two branches or merge two runs, without tools and without extra sealing compound. The group covers tube outside diameters from 3 to 16 mm, including reducing versions with two different port sizes. Working pressure reaches 10 to 16 bar depending on series, and down to -0.98 bar under vacuum.

What matters when choosing

• Tube O.D. 3 to 16 mm: besides equal-size ports there are reducing versions that take the main run straight to two smaller branches.
• Series: Blue Series and Blue Series mini for standard pneumatics, NonPlusUltra and metallica where plastic at the push-in port is not enough.
• Material: plastic with nickel-plated brass, fully nickel-plated brass, or stainless steel 1.4404. Stainless is the choice for cleaning and food-contact surroundings.
• Seal material NBR, FKM or FKM in FDA-compliant quality, which decides media and temperature compatibility.
• Medium and temperature: some connectors are released for compressed air only, others additionally for neutral gases, liquids, oil and grease at -20 °C to 150 °C.

Typical applications

• Splitting a supply line to two cylinders or two blow nozzles
• Connecting vacuum cups, where pressures down to -0.98 bar occur
• Control lines between valve manifold and actuator in handling equipment
• Lubricant and grease lines on the versions released for oil and grease
• Machine retrofits where an extra branch has to be added without tools

The 51 items in this group are built from plastic with nickel-plated brass, from nickel-plated brass, or from stainless steel 1.4404, sealed with NBR or FKM, the latter also in FDA-compliant quality. Manufacturing takes place in Germany, Italy and China.
