Grow1 TechLock Compression Coupler Fitting - 17mm - 25 Count

Tool-Free Tubing Joints for Drip Lines - 25 Couplers

Splicing or repairing drip tubing with clamps and glue is slow, and a weak joint can leak. This compression coupler joins two lengths of tubing with a push-and-twist motion and needs no special tools. It is rated for 0-100 PSI operating pressure and 67 ft-lbs of pull-out resistance.

One unit contains 25 couplers. That quantity suits a grower expanding a hydroponic system, a crew running a larger irrigation layout, or anyone who wants spares on hand for repairs.

Key Features & Benefits

• Push-and-twist connection — joins tubing without clamps, glue or special tools.

Frequently Asked Questions

Q: What tubing does this coupler fit?
A: It is listed for 1/4 in or 1/2 in drip tubing. Check your tubing against the listed dimensions: internal diameter 0.530-0.560 in, outside diameter 0.600-0.660 in and wall thickness 0.035-0.050 in.

Q: Do I need tools to install it?
A: No. The coupler connects with a push-and-twist motion, so you do not need clamps, glue or special tools.

Q: How many couplers come in one unit?
A: One unit holds 25 couplers. It is sold as a single unit.

Q: What does pull-out resistance mean?
A: Pull-out resistance is the force a fitting withstands before tubing separates from it. This coupler is listed at 67 ft-lbs.

Q: What pressure and temperature can it handle?
A: It is listed for operating pressure from 0 to 100 PSI. Its working temperature range is 32°F to 140°F.

Q: How does a compression coupler differ from a barbed coupler?
A: A compression coupler grips the tubing by tightening around it. A barbed coupler relies on ridges pushed into the tubing, and is often paired with clamps.
