PUC Inch Straight Union Pneumatic One Touch Fittings
The PUC inch straight union is a pneumatic quick connector for joining two tubes of the same outside diameter in a straight connection. Choose this inch-size one touch fitting by matching the tube OD to the selected option.
Tube sizes and packaging
Available tube outside diameters are 1/8, 5/32, 3/16, 1/4, 5/16, 3/8 and 1/2 inch. Each pack contains 10 pieces of the selected size.
Selection questions
Is this the metric PUC version? No. This listing is for inch tube outside diameters. Select the inch size printed on your tubing rather than a similar-looking metric size.
Does this fitting reduce the tube size? This is a straight union listing with one tube OD per variant, not a union reducer listing.
How do I select the size? Match the tube outside diameter, not the inside diameter, to the Application Tube option.
Are operating ratings specified? Pressure limits, temperature limits and tube-material compatibility are not stated in the current listing. Confirm these requirements before selecting for your application.
