What is the Viega ProPress Temperature Rating?
Viega ProPress Temperature Rating and MegaPress Temperature Rating Guide
The Viega ProPress System revolutionized the way pipes are joined by reducing connection time to 7 seconds or less and eliminating the need for burn permits and fire watches. As this method continues to grow in popularity, we hear many questions about proper use. As an authorized Viega distributor, a common question we are asked by customers is: What is the Viega ProPress temperature rating?
The answer to this is simply, it depends. Viega ProPress fitting temperature rating depends on your application and the metal type. The same is to be said for Viega MegaPress temperature rating. Viega provides us with temperature ratings in their Approved Applications Chart, which also includes pressure ratings for each product line, material, and sealing element. Please see the below charts for a quick reference for MegaPress temperature rating and ProPress fittings temperature ratings organized by media.
