About this item

A reducing compression coupling connects two different polyethylene pipe diameters in a straight irrigation run. Its opposing blue nuts have different socket sizes, joined by a stepped black body. This shape is useful where a supply line transitions to a smaller distribution pipe without adding a side branch or a threaded connection.

Check both pipe diameters

Measure the outside diameter of each pipe separately and compare the pair with the selected option. Do not assume that two pipes with similar-looking walls have the same connection size. Place the larger and smaller ends according to the intended route, leaving enough space for both nuts and keeping each pipe straight at insertion.

Match the pipe before assembly

Compression fitting sizes refer to the pipe connection diameter. Check the actual outside diameter, pipe material and wall specification rather than relying on an inside-diameter measurement. The selected option must match every connected pipe. Confirm the permitted pressure and temperature for your complete system before installation; the weakest component determines the usable operating limit.

Prepare and test the connection

Turn off the water and release pressure before working on the line. Cut the pipe square, remove loose debris and check the end for scratches or distortion. Follow the fitting assembly instructions for insertion depth, any required pipe support and tightening. Keep the sealing surfaces clean and avoid forcing a misaligned pipe into the socket. Bring the zone up to pressure gradually, inspect every connection and resolve any leakage before covering the pipe.

Choose the right fitting shape

Check the route and number of outlets as well as the size. Leave the joint accessible during the initial test and provide space for later inspection. A correctly selected fitting should suit the planned layout without twisting the pipe or putting unnecessary strain on the connection.
