What is the minimum distance between ProPress fittings?
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 grows in popularity, we hear many questions about proper use. The most common question we are asked by customers is: What is the minimum distance between ProPress fittings?
Viega answers this important question in the Viega ProPress Systems Installation Manual. Essentially the distance depends on the size of the tube diameter. Please use the chart below to determine the minimum distance required between two Viega ProPress connections (sizes 1/2 in - 2 in) and Viega ProPress XL connections (sizes 2-1/2 in to 4 in.) Note that where the minimum distance is 0 it is particularly important to ensure the correct insertion depth of the tubing into each fitting. Failure to maintain the safe distance may result in an improper seal.
|Tubing Diameter||Minimum Distance (inches)||Minimum Distance (mm)|
|1/2 in||0 in||0 mm|
|3/4 in||0 in||0 mm|
|1 in||0 in||0 mm|
|1-1/4 in||7/16 in||10 mm|
|1-1/2 in||5/8 in||15 mm|
|2 in||3/4 in||20 mm|
|2-1/2 in||5/8 in||15 mm|
|3 in||5/8 in||15 mm|
|4 in||5/8 in||15 mm|
