The Watts Pex-Cassette T20 Radiant Coupling Kit T20, model number 81005174, is a premium solution for connecting PEX (Cross-Linked Polyethylene) piping in radiant heating applications. This kit is specifically designed for 3/8-inch OD (Outside Diameter) PEX tubing and is compatible with Watts T20 series radiant manifolds.

The main component of this kit is the radiant coupling, which is a press-fit, push-to-connect coupling. It utilizes Watts' proven press-to-connect technology, ensuring a secure and leak-free connection every time. The coupling features an integrated O-ring seal, which provides an additional layer of protection against leaks. The coupling also includes a flow-through design that allows for easy flushing of the system.

The kit includes one radiant coupling and two male adapters, which are used to connect the coupling to the PEX piping. The adapters are also designed with Watts' press-to-connect technology, allowing for quick and easy installation. The adapters have a 3/8-inch OD and are suitable for use with both PEX-a and PEX-b piping.

The Watts Pex-Cassette T20 Radiant Coupling Kit T20 is made from high-quality materials, including brass bodies and stainless steel compression rings. This ensures that the coupling can withstand the rigors of radiant heating applications and provides long-lasting performance. The kit is also suitable for use with both domestic hot water and hydronic heating systems.

Installation of the Watts Pex-Cassette T20 Radiant Coupling Kit T20 is straightforward and can be completed in a few simple steps. First, clean and dry the piping and coupling. Then, press the coupling onto the piping, applying even pressure until the coupling seats firmly against the piping. Finally, use the provided compression nut and washer to secure the connection.

In summary, the Watts Pex-Cassette T20 Radiant Coupling Kit T20 is a high-performance, easy-to-install solution for connecting PEX piping in radiant heating applications. Its innovative design and use of proven press-to-connect technology make it a reliable and efficient choice for contractors and homeowners alike.
