Parker's Dubl-barb push-on hose barb is a compact one piece fitting for a quick, economical way to connect polyethylene tubing.
Parker's economical, one piece, Dubl-Barb® fittings are designed for quick assembly with polyethylene tubing without the use of a clamp. Because of the many available variations in qualities of polyethylene tubing, Dubl-Barb® fittings are recommended for use with Parker Parflex® polyethylene tubing (or an equal grade). Parker Parflex® tubing is highly resistant to environmental stress cracking which is necessary for long life when coupled with Dubl-Barb fittings. Assembly is simple, just cut tube squarely and push tube over the two barbs.
Use with Parker Parflex Division polyethylene tubing.
