F1960 Application Problems

Leak path. Expansion did not rotate between multiple

expansions, leaving a groove or leak path past the tting

barb. Expansion made with a defective expansion head.

Ring must be kept around 55ºF or greater to assure

expansion is uniform. Remove any expanded ring that

displays unequal expansion. Failure to rotate tool inside

tubing may cause unequal expansion.

Sunlight: PPSU and Polymer ttings and

plastic tube should be protected from UV

exposure.

Glue/Primers/Chemicals: PPSU and

Polymer ttings should be protected from

harmful chemical exposure. See CAUTION

for harmful chemical exposure in ASTM

F2159 (pg 16 & pg. 40).

Flame: PPSU and Polymer ttings should

not be soldered to or near (min. of 18"

separation when soldering). Flame or

heating sources beyond material tolerances

must be avoided.

Tube not cut squarely – ring and tube need to be mated

perfectly and installed fully over F1960 barb for a

viable seal.

Fitting not inserted completely into expanded tube

and ring.

Ring not fully covering PEX tubing.

Damaged, cut or grooved sealing barb.
