Barb Tubing Cross
Use a Barbed Tubing Cross when you need to create a junction splitting into four directions with the same size poly tubing.
Quality barbed fittings provide high retention in low-pressure poly tubing for long-term reliability of connections. The acetal fittings can be confidently installed without clamps when matched with our quality low-pressure poly tubing with corresponding dimensions. See note below on gray PVC fittings.
- 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 hole into the side of the larger tubing with any of our 1/4" punch tools. 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.
Gray PVC insert fittings are made of the same substances as schedule 40 and schedule 80 PVC are made of. This means a durable long lasting fitting. Insert fittings are normally used with flexible pipe, hose or tubing. Simply slip the barbed insert tip all the way into the flexible pipe, hose or tubing. Multiple sharp barbs provide a tight grip on the flexible materials to create the seal. Insert fittings may require clamping to provide a reliable leak-proof seal. Proper clamping technique is to place the clamp directly over the barb area and tighten.
