This compact BloomLED fitting is a must-have for any indoor drip system. Designed for flexible 4 to 6 mm inner-diameter tubing, it lets you extend a capillary line, repair a punctured section or splice two pieces of distribution hose without disassembling the whole network. Its double-barb clip locks both tubes in place instantly — no clamps, no leaks.

Slide each tube end onto the barbs and clip closed — the connector locks itself. No hose clamps or zip-ties needed; ideal for quick repairs mid-cycle.
The double barbs grip the inner wall of the hose and keep the joint leak-free, even under pump pressure or gravity-fed systems.
Hand-picked by BloomLED for grow-tent irrigation, flood tables and auto-pot setups. Works with all common 4 mm and 6 mm capillary brands.
Yes. As long as your capillary line has a 4 or 6 mm inner diameter, you can splice this connector between your main hose and the drippers without any noticeable pressure loss.
How do I fix a punctured hose with this fitting?Cut the tubing cleanly on each side of the leak, push both ends onto the barbs and clip closed. The seal restores full flow in under a minute.
Tiny part, big impact: one punctured tube can halt your whole watering cycle. BloomLED keeps this connector in every serious indoor grower's toolkit.
