Harco 75-13055 Polyethylene Adapter 1-1/4 in Compression X Mipt

Product Description

The HARCO 75-13055 is a polyethylene compression-to-MIPT adapter fitting designed for connecting water service pipe to threaded fittings and components. Part of the Philmac 3G series, this adapter features a 1-1/4 inch compression inlet and a 1-1/4 inch male iron pipe thread (MIPT) outlet. It is rated for 230 psi, making it suitable for standard residential and light commercial water service applications. The fitting is manufactured from polyethylene for corrosion resistance and long-term performance in buried or above-grade water service installations. Plumbers and water service contractors install this fitting as a transition point between flexible pipe and threaded components.

This adapter is designed for use with ASTM D2737 polyethylene (PE) and ASTM F876 PEX water service pipe at the 1-1/4 inch size. Typical applications include water service laterals, meter connections, and other potable water distribution transitions where a compression-to-threaded connection is required. The Philmac 3G series is commonly specified for both new installations and repair work in residential and light commercial water service systems.

Key Features

• 1-1/4 inch compression inlet connects directly to PE or PEX water service pipe without solvent cement or heat fusion
• MIPT outlet threads onto standard iron pipe thread fittings and valves
• 230 psi pressure rating suitable for typical water service line pressures
• Polyethylene construction resists corrosion and is compatible with potable water service
• Philmac 3G series design for reliable, long-term field performance
• Compatible with both ASTM D2737 PE and ASTM F876 PEX pipe

Compatibility

Designed for use with ASTM D2737 PE and ASTM F876 PEX water service pipe at the 1-1/4 inch size.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with local plumbing codes and IPC requirements. Shut off the water supply and relieve system pressure before making or breaking any connections. Ensure pipe ends are cut cleanly and squarely and are free of burrs before inserting into the compression fitting. Do not overtighten the MIPT connection; use thread sealant tape or compound rated for potable water applications.
