Netafim 17mm TechLock – Elbow 25 pack

The Netafim 17mm TechLock Elbow (25 pack) is a compression-style elbow fitting designed for use with 17mm UV polyethylene drip tubing. Barb ends grip the tubing securely while TechLock threaded caps and compression rings create a leak-free seal rated for 0–100 psi. Each pack contains 25 elbows, covering a full row or zone layout in a single purchase.

Why Choose Netafim 17mm TechLock Elbows

Netafim’s TechLock system uses a two-part locking mechanism: barbed ends that grip the inner wall of 17mm tubing and threaded compression caps that clamp the fitting in place from the outside. Once installed, the connection does not pull free under normal operating pressures. This matters in drip irrigation runs where gradual pressure fluctuations can work plain barb fittings loose over a season.

The 0–100 psi pressure rating covers the full range of delivery pressures used in greenhouse and indoor drip systems, from gravity-fed low-pressure setups to pump-driven lines with pressure regulators. Because the fitting is rated at the high end, you are not forced to reduce line pressure to protect the connection.

• TechLock compression ring creates a secure seal that holds across pressure fluctuations without relying on friction alone
• Barb profile sized specifically for 17mm UV polyethylene tubing — no adapters needed when using HGC747559 tubing
• Threaded cap design allows the fitting to be removed and reused if the layout changes between grow cycles
• Pack of 25 covers a full zone or row in a single purchase, reducing the need for repeat orders mid-install
• Operating pressure range of 0–100 psi accommodates both gravity-fed and pump-driven drip lines

Best Uses for Netafim 17mm TechLock Elbows

Elbow fittings are used anywhere a drip line needs to change direction — turning a corner, routing tubing around a reservoir, or bending a run to follow the perimeter of a raised bed or flood table. The 17mm format is the standard diameter for main-line tubing in most greenhouse drip irrigation layouts, so these elbows pair directly into existing 17mm infrastructure without reducers.

• Greenhouse and indoor drip irrigation layouts where main lines must turn 90° at walls, posts, or table edges
• Commercial and hobby hydroponic systems using 17mm UV polyethylene tubing as the main supply line
• Flood-and-drain or top-feed drip setups where tubing routes around reservoir edges before splitting to emitters
• Row crop or container-garden drip runs that follow the perimeter of a growing space and require directional changes
• Replacement of worn or cracked elbow fittings in an existing Netafim 17mm drip network
• New system builds where a full zone is being plumbed from scratch — 25 fittings covers most single-zone layouts

If your system also uses a water filtration stage before the drip lines, a 1-1/2 in. inline filter with 200-mesh screen keeps particulates out of emitters and fittings. For monitoring nutrient solution quality in the reservoir, an Apera GroStar EC replacement electrode pairs with compatible Apera meters to track conductivity between feed cycles.
