Grow1 TechLock Compression Coupler Fitting - 20mm - 25 Count

Join Drip Tubing Without Clamps or Glue - 20mm

Splicing drip tubing with clamps or glue is slow, and a joint that seeps wastes water and nutrient solution. The Grow1 TechLock compression coupler locks onto 1/4 in or 1/2 in drip tubing with a push-and-twist motion and needs no special tools. It is rated for 0-100 PSI and a pull-out resistance of 67 ft-lbs, so lines stay connected under normal working pressure.

This unit holds 25 couplers, enough for a mid-sized indoor hydroponic setup, a greenhouse line expansion, or a stock of spares for repairs. Commercial crews running longer lines will find the count practical for repeat installs, and home growers get enough for a full build plus replacements.

Key Features & Benefits

• Push-and-twist compression design — connects tubing quickly by hand, with no clamps, glue or tools.
• Reusable fitting — designed for easy reuse, so you can rework a layout without replacing every coupler.
• Works with 1/4 in or 1/2 in drip tubing — one coupler style covers both common tubing sizes.
• 0-100 PSI operating pressure — suits typical drip and low-pressure irrigation lines.
• Dark colour — blends with dripline tubing for a neat finish.

Who Should Use Grow1 TechLock 20mm Compression Coupler Fitting

Use it if you build, extend or repair drip irrigation, hydroponic feed lines or greenhouse watering systems. It suits installers who want fast, tool-free joints and growers who reconfigure their layouts often.

About Grow1 TechLock 20mm Compression Coupler Fitting

Grow1 makes the TechLock series of compression fittings for irrigation, hydroponics and drip systems. This 20mm coupler is a compression-type fitting that joins two lengths of tubing. It works across a 32°F-140°F temperature range. Specified tubing is 0.530-0.560 in inside diameter, 0.600-0.660 in outside diameter and 0.035-0.050 in wall thickness.

Frequently Asked Questions

Q: Do I need tools to install this coupler?
A: No. The fitting locks onto the tubing with a push-and-twist motion by hand. You need no clamps, glue or special tools.

Q: Which tubing does it fit?
A: It is made for 1/4 in or 1/2 in drip tubing. Check that your tubing falls within the listed diameter and wall-thickness ranges before a large install.

Q: Can I reuse the fitting?
A: Yes, it is designed for easy reuse. That makes it practical when you adjust a layout or repair a line.

Q: What does pull-out resistance mean?
A: It is the force needed to pull tubing out of a fitting. This coupler is listed at 67 ft-lbs.

Q: What pressure and temperature can it handle?
A: It operates from 0-100 PSI and in temperatures from 32°F to 140°F. Keep your system within both ranges.

Q: How does a compression coupler differ from a barbed one?
A: A compression coupler grips the tubing with a locking mechanism, while a barbed coupler relies on friction over ridges and often needs a clamp. Compression styles are usually faster to install and easier to remove.
