Harco 75-351666 Philmac 3G Compression Tee 1.5 in

Product Description

The HARCO 75-351666 is a Philmac 3G series compression service tee designed for use with CTS and IPS OD polyethylene (PE) pipe. This fitting connects two compression ends to one female NPT (FNPT) threaded outlet, forming a 90-degree tee configuration in a single assembly. Rated to a maximum operating pressure of 230 psi, it is built for service lines where reliable, leak-resistant joining of PE pipe is required. The plastic construction resists corrosion and keeps weight low at 1.4 pounds. Licensed plumbers and waterworks technicians are the primary installers of this fitting type.

This tee is suited for residential and light commercial water service applications where CTS or IPS OD PE pipe is used for distribution or service lateral work. The compression connection style allows field assembly without solvent welding or heat fusion equipment, making it practical for repair and new installation scenarios. All three connection sizes are 1.5 inches, with the third port configured as a female NPT thread for transitioning to threaded pipe or equipment.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and applicable IPC provisions. Shut off and depressurize the water service line before disassembly or fitting installation. Verify that pipe ends are cut square and free of burrs before seating into the compression body. Confirm that the connected pipe OD matches either CTS or IPS OD standards before assembly, as mixing incompatible pipe dimensions can result in joint failure.
