Unipipe Installation Instructions

Use the download link for instructions on the installation of different types of Unipipe fittings.

1 CUTTING: Cut the pipe using burr-free approved cutters. Do not use oxy-acetylene or abrasive cut off wheels. Pipes must be cut at right angles to their axis, using a pipe cutter or fine-tooth saw, allowing for the depth of insertion into the fitting.

2 DEBURRING: All pipe cuts must be carefully deburred, both inside and outside, using a manual or electric deburring tool. Any cutting residue (swarf) must be removed to avoid damage to the O-ring when the pipe is inserted into the fitting, avoiding possible leaks.

3 MARK INSERTION DEPTH: To ensure a correctly inserted joint, the pipe must be marked with a fine-point marker to show the insertion depth in the fitting, or by measurement using the table below. The use of a Unipipe Depth Gauge is recommended.

4 LOOSEN NUT: Check that all components are correctly positioned inside the fitting.

5 LUBRICATION: Use soapy water, silicone spray or a lubricant that is compatible with the intended use.
Lubrication is optional, but will assist inserting the pipe through the seal ring. Do not use silicone spray if intended use is for powder coating, spray painting or breathing air.

6INSERT and TIGHTEN: Insert the pipe up to the mark, ensuring the axis of the pipe and the fitting are straight. Tighten the nut by hand and then with a wrench for 1/4-turn more or until the pipe starts to turn. DO NOT OVERTIGHTEN.
