Hiboom Drip Tape Takeoff Adapters 5/8 x 1/4 50-Pack — Extended Barb & Green T-Handle Shutoff

Hiboom 50-piece drip tape takeoff adapters are 5/8" (16 mm) x 1/4" barb fittings with an extended barb and T-handle shutoff that let you connect and isolate individual drip tape lines quickly and securely.

These takeoff adapter valves are designed for low-pressure drip irrigation systems and give you a simple way to tap a mainline poly tube and run a controlled drip tape branch. Each fitting combines an extended barbed connection for a tight hose seat, a thumb/green T-handle shutoff for on-demand isolation, and durable POM construction that resists UV and oxidation. They come in a pack of 50, making them suitable for medium to large beds, greenhouse rows, or multi-zone home gardens.

How do these adapters connect to my mainline and drip tape?

Installation is straightforward: punch a hole in the main polyline, insert the extended barb into that hole, and push the drip tape onto the smaller 1/4" outlet. The longer barb improves grip and reduces leaks compared with shorter fittings.

• Punch a clean hole in 1/2", 3/4" or 1" mainline poly tubing
• Insert the extended 5/8" (16 mm) barb for a snug seal
• Attach 1/4" (6 mm) drip tape or tubing to the outlet and close the T-handle to stop flow

What flow and durability can I expect from these valves?

Each adapter supports a flow rate that can exceed about 80 GPH at 10 PSI when used with compatible drip tape and system pressure. The body is molded from POM material for improved resistance to UV degradation and oxidation, helping the valves last through multiple seasons.

• Rated to exceed ~80 GPH at 10 PSI with proper system setup
• POM construction resists UV and chemical breakdown
• Extended barb reduces rework and leak points

Which tubing sizes and hook options should I use for best results?

The takeoff adapter is compatible with common mainline sizes but requires matching barb choices depending on tube diameter and run length. Use the smaller 3.6 mm barb for short connectors and the larger 7.0 mm barb for longer runs; avoid using the 7.0 mm barb with a 1/2" mainline to prevent fit issues.

• Works with 1/2", 3/4" and 1" poly mainlines (observe barb size restrictions)
• 3.6 mm barb recommended for short tubing spans
• 7.0 mm barb recommended for longer tubing—except on 1/2" pipe

How does the shutoff feature help maintain and manage zones?

The integrated T-handle shutoff allows you to isolate a single drip tape line without disturbing the rest of the system. That makes pruning, plant replacement, or seasonal adjustments quicker and reduces the need to shut the entire irrigation run off.

• Green T-handle gives quick manual control for each takeoff
• Isolate individual rows for maintenance or seasonal changeover
• Saves water by stopping leaks or unused branches instantly

Who is this for? The Hiboom 50-piece takeoff adapters suit gardeners, small farmers, landscapers, and greenhouse operators who need reliable, low-cost fittings to expand or repair drip tape networks. They are ideal when you want large-quantity, easy-to-install connectors with manual shutoff for individual lines—helpful in vegetable beds, raised planters, orchard rows, and commercial greenhouse benches. These fittings are not a substitute for pressure regulation or filtration; add appropriate system components for best performance.
