When joining PEX-A tubing using the expansion method, what must be done immediately after the pipe end is expanded?
-
A
Assemble the fitting immediately — PEX-A has shape memory and will contract to grip the fitting barb as it warms
-
B
Cool the expanded tube in cold water before pushing onto the fitting
-
C
Expand the tube a second time to ensure a tighter fit before assembly
-
D
Chill the fitting in ice water to reduce its diameter for easier insertion
