Dubl-Barb® Fittings
Advantages
Compact one-piece, push-on barbed ftting for a quick, economical way
to connect polyethylene tubing. In addition to the styles shown, custom
DUBL-BARB fttings to meet your exact requirements are available.
Machined from CA 360 or CA 345 brass.
Applications
Because of the many available variations in qualities of polyethylene
tubing, DUBL-BARB® fttings are recommended for use with Parker
Parfex® polyethylene tubing (or an equal grade). Parker Parfex® tubing
is highly resistant to environmental stress cracking which is necessary
for long life when coupled with expansion fttings.
