Extend a drip line, repair a cut hose or splice two sections of 16 mm flexible PE pipe. This BloomLED straight connector does the job cleanly: barbed insertion and tight tolerances lock the pipe even under the pressure of a small immersion pump or an automated indoor irrigation controller.

Internal barbs grip the pipe wall and stop water from creeping back. For most low-pressure indoor setups no extra clamp is needed.
Briefly soften the pipe in warm water if needed, push it home and the line is repaired in seconds.
Handles the constant humidity of a grow tent, exposure to liquid nutrients and long hours under LED grow lights.
No. It is sized for 16 mm outer-diameter flexible PE pipe. Use our dedicated micro-irrigation fittings for 4/6 mm and our larger reference for 20 mm hose.
Do I need a hose clamp on top of the connector?For typical indoor pressure (gravity or low-pressure pump) the connector alone is enough. Above a permanent 3 bar working pressure a small stainless clamp gives extra peace of mind.
