▶ Measure insertion depth (see table below).
▶ Mark the proper insertion depth on the outside of the tube.
Improper insertion depth
Improper insertion depth may result in an improper seal.
■ Be sure to mark the correct insertion depth on the tube
before pressing the fitting.

Table 23: Insertion depths for ProPress XL-C 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 fitting onto the tube to marked insertion
depth.
Note: End of tube must contact stop.
