Definition
PE-RT is a polyethylene (PE) resin in which the molecular architecture has been designed to incorporate a sufficient number of tie chains to allow operation at elevated or raised temperatures (RT). Tie chains "tie" together the crystalline structures in the polymer, resulting in improved properties such as elevated temperature strength and performance, chemical resistance and resistance to slow crack growth.
PE-RT tubing comes in nominal sizes ranging from 1/4 to 6 in. copper tube size (CTS). PE-RT tubing is SDR9 with standard hydrostatic pressure ratings of 200 psi at 73°F (1379 kPa at 23°C) and 100 psi at 180°F (690 kPa at 82°C). Consult the specific PE-RT manufacturer's literature and listings for appropriate pressure ratings. PE-RT tubing and pipe are sold in coils and straight lengths.

Overview
PE-RT is a high-temperature flexible plastic pressure pipe with a 35-year history of successful use in the European market, and it has been extensively tested for durability and material performance. It was first introduced in North America in 2003 and used in aluminium composite (multilayer) barrier tubing, solid wall tubing, and pipe. Applications include plumbing, water service, hydronic heating and cooling, snow and ice melting and ground-source geothermal piping systems. PE-RT is approved in all model plumbing and mechanical codes across the United States.
