Table 20: Insertion depths for ProPress non-stop couplings
Non-stop couplings and extended non-stop couplings are often used to
conduct repairs. Without a stop, these couplings can slide completely
onto a tube and allow a connection to be made in tighter spaces. Unlike
fittings with an integrated stop that have a minimum insertion depth,
non-stop couplings have minimum and maximum allowable insertion
depths. Both the minimum and the maximum insertion depths must be
marked and a line connecting the two marks. Drawing a line between the
minimum and maximum insertion marks distinguishes a good connection
on a non-stop fitting from a bad connection on a fitting with a stop.

While turning slightly, slide press fitting onto the tube to the marked
insertion depth.
Note:
End of tube must contact stop.
