▶ 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 󶈵tting.

Table 22: Insertion depths for ProPress 2½" to 4" no-stop couplings
No-stop couplings and extended no-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
󶈵ttings with an integrated stop that have a minimum insertion depth, no-
stop couplings have minimum and maximum allowable insertion depths.
Both the minimum and the maximum insertion depths must be marked
with a line connecting the two marks.
▶ While turning slightly, slide 󶈵tting onto the tube to marked insertion
depth.
Note: End of tube must contact stop.
