Q1P03 Gas-Electric Rotary Union
The Q1P03-GAS-ELECTRIC is a pneumatic rotary union for transferring air or vacuum across a rotating interface. This model has 86 mm OD, and is part of the Q series, which also includes gas-electric versions that carry electrical channels in the same unit.
Typical applications: pneumatic chucks and collets, vacuum suction heads on rotating arms, air cylinders on indexing tables, and coolant or air supply to rotating tooling.
Selection notes: pure pneumatic units are rated −90 kPa to 1 MPa at up to 300 rpm; gas-electric combined units are rated −80 kPa to 0.8 MPa at up to 250 rpm. Choose the combined version when the same joint must carry both fluid and power or signals. Life expectancy for the Q series is 20 million revolutions.
GUREN machines and assembles rotary unions in-house and pressure-tests each unit before delivery.
Custom circuit counts, lead lengths, connector types and mounting flanges are quoted on request, and in-house machining keeps lead times short for both standard and modified units.

Frequently asked questions — Q1P03
What does the Q1P03 combine?
It combines 1 in 1 out gas channels with 6 / 12 / 18 / 24 electrical circuits, passing compressed air or vacuum and power/signal through the same rotating axis.
What gas pressure and medium are supported?
Compressed air, vacuum and inert gas. Pressure range and medium should be confirmed at order against the seal specification.
Which hose and interface does it take?
Interface G3/8″, suitable for 10-12 mm hose.
Can gas and electrical channels be customised?
Yes. Channel count, interface thread and circuit count are built to order.
