The Viega Propress 20728 1/2 Coupling is a copper press fitting with an extensive length of 0.915 inches (23.23 mm), part of the Viega Propress XL series. This fitting is engineered for use in potable water applications and comes with a versatile 1/2 inch (16 mm) connection size, allowing it to join copper pipes of corresponding dimensions. The Viega Propress fitting uses the advanced Propress technology, a pioneering press-and-seal joining method that delivers several benefits over traditional soldering or compression fittings.
The Propress 20728 1/2 Coupling features a robust copper body with an inside diameter of 11/16 inches (18 mm). Its innovative design incorporates an expansion chamber, which absorbs pressure fluctuations during operation and protects the connection from pipe movements. This expansion chamber also provides an exceptional seamless fillet welded transition between the copper body and the crimp ring for enhanced leak prevention and durability. The crimp ring, which is designed for press durability, comes with a specialized grease coating that ensures the optimal press function for reliable connections.
The Viega Propress 20728 1/2 Coupling also comes with a built-in O-ring seal, which is compressed during the press process to create a tight and reliable seal. This O-ring ensures the connection does not leak but still allows for thermal expansion and contraction. Furthermore, the tool-less grip mechanism on the crimp ring makes the installation process more accessible and convenient, allowing for quick connections without the need for additional tools.
The Propress XL series, to which the 20728 fitting belongs, provides extended lengths compared to the standard series. The extended length offers a more straightforward installation process when dealing with longer pipe runs, and it reduces the number of required fittings.
In summary, the Viega Propress 20728 1/2 Coupling is a durable and efficient solution for joining copper pipes in potable water applications. Constructed using advanced Propress technology, it provides robust press connections with the added benefits of a seamless fillet weld and an expansion chamber for added durability and reliability. Its extended length and easy installation make it a preferred choice for plumbing professionals and DIY enthusiasts alike.
