About the Airtac PEW T-Type Side Reducing Tee Fitting PEW12-10
The PEW12-10 is an AirTAC different diameter union Y, a tube-to-tube push-to-connect fitting that splits a single Dia 12 mm line into two Dia 10 mm branch legs in one moulded body. There is no threaded port here; all three legs are tube sockets. Push each tube home and the internal chuck grips its outside diameter, the stainless spring gasket and NBR O-ring seal it, and pressing the POM release ring frees the tube again.
This is the resin one-touch profile, not the metal BPC line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The grey body pairs a POM chuck and release ring with an aluminium-alloy guide, and it accepts soft nylon or polyurethane tubing only. Because both branch legs are one size down from the trunk, this one part does the job of a same-size Y plus two reducing adaptors, and removes two potential leak joints from the circuit.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac PEW T-Type Side Reducing Tee Fitting PEW12-10 Is Used
Bottling line branch feed
A 12 mm trunk running along a bottling conveyor splits into two 10 mm drops feeding pneumatic cap-settling vibrators, with no adaptor stack between the trunk and the actuators.
Twin-gripper pick head
On a packaging pick-and-place head, one 12 mm feed from the valve manifold Y-splits into two 10 mm lines serving parallel grippers, keeping the end-of-arm tubing loom short and light.
Carton vacuum transfer
A vacuum branch on a carton erector drops from a 12 mm suction main to twin 10 mm cup lines; the -750 mmHg rating means the same part works on the suction side as on pressure.
Is the Airtac PEW T-Type Side Reducing Tee Fitting PEW12-10 the Right Part?
Dia 12 is the largest tube size in this catalogue, so this Y sits at the top of the ladder; there is no larger PEW to step up to. If your trunk drops to 10 mm, the PEW10-8 does the same job one size down, and if both legs stay at 12 mm the plain PY12 same-size union Y is the simpler part. With no thread on the body, your sizing decision is purely about tube outside diameter on each of the three legs.
Tube OD must match exactly on every leg. The Dia 10 sockets will not seal on 3/8in tube, which measures roughly 9.5 mm OD and will either leak or blow out under pressure; the Dia 12 end will not grip 1/2in tube either. Keep to soft nylon or polyurethane, and remember the tube, not the fitting, is usually the first limit near the 70 C top of the range.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
Airtac PEW T-Type Side Reducing Tee Fitting PEW12-10 FAQ
It is a Dia 12 x Dia 10 different diameter union Y with no threaded port. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the service temperature range is -20 to +70 C. Use soft nylon or polyurethane tubing only, cut square and pushed fully home.
No. A one-touch chuck grips one exact outside diameter, so the small legs take 10 mm tube only. 3/8in tube measures about 9.5 mm OD, which is undersize for the seal and will leak or blow out under pressure. If your circuit is built on imperial tube, this metric fitting is not the part for it.
