HydroSure Compression Fitting - Blue - Pack of 3

These fittings are designed specifically for 25mm MDPE (Medium-Density Polyethylene) and HDPE (High-Density Polyethylene) pipes.

Yes, while designed for underground use, they are also suitable for above-ground installations due to their UV-resistant construction.

Ensure the pipe is cut square and clean, fully inserted into the fitting, and the compression nut is tightened firmly. The compression design inherently creates a watertight seal when properly installed.

The male thread size for connecting to sprinklers or other outlets is 3/4 inch.

No special tools are required for basic installation. The compression nut can be tightened by hand, though a wrench can be used for a final secure tightening.

The blue color is often used for identification within irrigation systems, typically indicating potable water lines, though this is a manufacturer standard and not a universal functional requirement.

Ensure the pipe is fully inserted into the fitting and the compression nut is tightened securely. Check that the pipe end is cut square and clean, free from debris or damage.

Verify that you are using the correct size pipe (25mm MDPE/HDPE). Ensure the pipe end is not deformed or damaged. Slightly warming the pipe end in warm water can sometimes help with insertion.

Check for any cross-threading or debris in the nut or fitting threads. Ensure the pipe is seated correctly within the fitting before attempting to tighten.
