PU Straight Push-in Unions

About PU straight push-in unions

PU straight push-in unions connect two pneumatic tubes in line through a push-in tube port at each end. This is a tube-to-tube fitting, not a threaded adapter or a coil of pneumatic tubing. The listed model references for inquiries are PU6 and PU10.

Choose the complete model reference and specify the tube outside diameter at both ends, tube material, required quantity and unit, and operating conditions. Confirm dimensions, component materials and fit for the exact quoted configuration before ordering. The images are concept illustrations, not verified photographs of every size.

Frequently asked questions

Does PU mean the fitting body is polyurethane?

No material is inferred from the series code. Ask for the body, gripping-component and seal information of the exact configuration being quoted.

Is this page for pneumatic tubing?

No. It describes straight tube-union fittings. See Pneumatic Tubing for tube size references.

When should I review a PV elbow instead?

Use PU for an in-line tube connection. For a right-angle tube-to-tube connection, review PV Push-in Union Elbows and confirm both tube ends for the quoted model.
