Product Description
Barbed Connector.  Used to connect two pieces of tubing. 

Quality barbed acetal fittings provide high retention in low-pressure poly tubing for long-term reliability of connections. These fittings can be confidently installed without clamps when matched with our quality low-pressure poly tubing with corresponding dimensions.


  • Sharp-edged barbs create leak-proof seal.
  • Increased strength and superior quality.
  • Heat, chemical and wear-resistant.
  • UV stabilized materials for long life.

Special Note:  1/4" barbed fittings have the unique ability to be "snapped" into larger tubing after punching a 1/4" hole into the side of the larger tubing.  This creates a water tight seal and allows you to "tee-off" of larger diameter tubing using only 1/4" fittings and a hole punch.
