The AQUATHERM 1070000000 is a hex-shaped threaded transition fitting designed to connect polypropylene pipe systems to brass male iron pipe (MIP) threaded connections. It features a 3/4-inch socket weld end that heat-fuses directly to compatible PP-R or PP-RCT pipe and a 3/4-inch brass male hex threaded end for connection to threaded fittings, valves, or equipment ports. The hex body profile allows for standard wrench engagement during installation. This fitting is manufactured from polypropylene and is intended for installation by licensed plumbers working on hydronic, mechanical, or process piping systems where a transition from fusion-joined plastic pipe to a threaded metal connection is required.
This transition piece is suited for residential and commercial mechanical piping applications where PP-R or PP-RCT piping systems must interface with brass-threaded components such as valves, gauges, pumps, or equipment connections. It is part of the broader Aquatherm transition fitting family, which includes brass and steel threaded fittings, flange adaptors, PEX adapters, and copper stub outs designed to integrate polypropylene piping with other system types. Typical install scenarios include hydronic heating and cooling systems, domestic hot and cold water distribution, and industrial fluid handling systems using Aquatherm polypropylene pipe.
Designed for use with Aquatherm PP-R and PP-RCT polypropylene piping systems at the 3/4-inch size. The socket weld end is compatible with standard Aquatherm heat fusion tooling and 3/4-inch Aquatherm pipe. The brass MIP threaded end connects to any standard 3/4-inch female threaded fitting or port.
Installation of the socket weld end requires proper Aquatherm-approved heat fusion equipment and must follow established polypropylene heat fusion procedures. A licensed plumber should perform this work in accordance with applicable plumbing codes including the IPC and local authority requirements. Shut off and depressurize the piping system completely before making any connections. Do not apply thread sealant tape or compound to the socket weld end; use appropriate thread sealant only on the brass MIP threaded connection.
