FastPipe is a flexible, multilayer composite piping system designed specifically for mini-split and VRF/VRV air-conditioning installations. Unlike conventional soft copper, each FastPipe line set is factory-insulated, UV-resistant, and bends easily around tight corners— reducing installation time by up to 70 percent and eliminating damaged or kinked tubing on site.
Rated for working pressures to 870 PSI and compatible with today’s high-pressure refrigerants (including R-32 and R-454B), every FastPipe line set is pressure tested 100% at the factory for leak-free reliability. All the fittings come with a factory flare to minimize install errors and differences in copper.
The result is a lighter, more adaptable alternative to copper that saves labor, minimizes waste, and stands up to outdoor exposure thanks to its proprietary UV-Pro coating. FastPipe’s time-saving design fits perfectly with RST Thermal’s system-based approach to efficient, high-quality HVAC installations.
