The HARCO 75-33066 is an HDPE water compression male adapter designed for use in potable water distribution and plumbing systems. This fitting connects high-density polyethylene pipe to IPS-threaded components using a compression-style connection, eliminating the need for heat fusion tools in the field. At 1-1/2 inches IPS, it bridges HDPE mainline pipe to threaded valves, meters, or service connections. Licensed plumbers and water service contractors install this fitting during new water service installations and system repairs where a reliable, leak-resistant mechanical joint is required on HDPE pipe runs.
This adapter is suited for residential and light commercial water service applications where HDPE pipe meets threaded metal or plastic components. It is commonly installed at meter connections, valve inlets, and service entry points. The compression design allows installation without specialized fusion equipment, making it practical for field repairs and tight-access installations. It is intended for cold water distribution service in underground or above-grade configurations where IPS-dimensioned HDPE pipe is specified.
Designed as an OEM-style replacement and standard fitting for 1-1/2 inch IPS HDPE water service pipe systems.
Installation is performed by licensed plumbers or water service contractors in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting into existing pipe or making connections. Ensure the pipe end is cut square and deburred before seating it into the compression fitting. Do not overtighten the compression nut, as HDPE pipe can deform under excessive mechanical force.
