Raindrip Barbed Valve - 2pk - For 1/4in Tubing

Per-Container Flow Control Valve for 1/4in Drip Lines, 2pk

A shared drip line often runs one container that needs a heavier soak next to one that needs almost nothing, and a single fixed-rate emitter can't serve both well. Raindrip's barbed valve solves that at the individual container level, letting a grower turn the top cap to dial output anywhere from full flow down to fully closed at that one site, without touching the rest of the line.

The 2-pack outfits a couple of containers needing independent flow control, or provides a spare for an existing setup.

Key Features & Benefits

• Adjustable top cap — turns to dial flow from fully open to fully closed at each individual emitter point.
• Per-container control — adjusts output at each plant site independently without affecting other emitters on the same line.
• Barbed connection — pushes directly onto 1/4in drip tubing for tool-free, secure installation.
• 2-pack — includes two valves for use at multiple container sites or as replacements.
• Compact, low-profile design — the valve fits neatly at the growing media surface without disrupting plant spacing.

Who Should Use This

Container growers, hydroponic operators, and home gardeners running 1/4in drip lines who need adjustable, per-plant flow control at individual growing sites rely on this valve.

Frequently Asked Questions

How do I adjust the flow rate?

Turn the top cap clockwise to reduce flow and counterclockwise to increase it; turning it fully clockwise shuts the valve off completely. Small turns make a noticeable difference in output, so adjust gradually while observing flow at the emitter.

Can I use these as a permanent shutoff for a specific container?

Yes, fully closing the top cap shuts off flow to that container without affecting others on the same line. That makes it easy to pause watering for one plant, such as during transplant recovery, without disturbing the rest of the system.

Are these compatible with all 1/4in drip tubing brands?

The barbed connection fits standard 1/4in (about 0.25in inner diameter) drip tubing from most irrigation brands. Confirm your existing tubing's inner diameter matches before ordering to ensure a secure, leak-free push-fit.

Can I daisy-chain multiple containers from one valve?

No, these valves are built for single-point emitter control; for multi-container runs, use a manifold with an individual emitter for each container instead. A manifold paired with individual valves at each outlet gives you the same per-container control across a larger group.
