GXXMEI Micro Drip Emitters 200-Pack Adjustable 1/4-inch Threaded Black — 1–70 L/h Flow, 360° Rotating Cap

GXXMEI 200PCS adjustable micro drippers are 1/4-inch threaded plastic emitters that deliver 1–70 L/h and a 0–0.5 m spray radius for precise low-pressure watering.

These compact, black plastic emitters are designed for home gardens, greenhouses and small-scale agricultural systems that use 4mm/7mm tubing. Each unit connects to standard 1/4-inch barbed tubing, offers a wide adjustable flow range and a rotatable cap for 360° dispersion or complete shutoff. The pack of 200 supplies enough points of watering for patios, flowerbeds and vegetable rows while allowing individual control at each emitter.

How adjustable are the GXXMEI drippers and what flow rates can I expect?

The cap on each dripper rotates to vary flow from a trickle to a higher output, with a rated range of approximately 1 to 70 L/h depending on system pressure. The ratchet-style cap enables precise settings and can be fully closed to stop water at any emitter.

• Adjustable range: about 1–70 L/h.
• Rotation adjusts throw diameter and flow; full open covers roughly a 10–12 inch circle.
• Cap removable for cleaning and blockage checks.

Will these emitters work with my tubing and low-pressure setup?

Yes — the drippers use a 1/4-inch barb thread fitting compatible with 4mm inner / 7mm outer diameter tubing and perform well at low working pressures (1–3 KG). They maintain consistent output despite moderate pressure fluctuations when installed correctly.

• Thread diameter: 1/4 inch for standard micro tubing.
• Working pressure suitable: 1–3 KG (low-pressure systems).
• Tip: warm tubing in 70–80°C water for 10 seconds before insertion to ensure a snug fit.

How do these drippers distribute water and what pattern can I expect?

Each emitter has eight spray holes and a rotatable head that gives a 360° distribution when open, creating a gentle sprinkler effect ideal for root-zone and surface coverage. The slow, even application helps water soak into soil rather than run off.

• Spray radius: approximately 0–0.5 meters depending on setting and pressure.
• Eight-hole design for even, slow delivery to roots and surrounding soil.
• Can be set to full circle, partial arc, or closed for targeted irrigation.

What maintenance and installation tips should I follow?

Install by pushing the barb into compatible tubing after softening the tube end in warm water for a secure seal; periodically open the cap for cleaning and remove debris. These emitters are low-maintenance but benefit from occasional flushing of the main line and visual checks for clogging.

• Soften tubing in 70–80°C water for 10 seconds before assembly for tighter fit.
• Remove cap to inspect and clear mineral or particulate buildup.
• Flush main lines periodically to reduce clogging risk in emitters.

Who is this for: gardeners, hobby farmers and landscapers who need economical, flexible micro-irrigation points for pots, balconies, raised beds, lawns and greenhouse rows. The pack of 200 suits installations requiring many emitters or spare parts, and the adjustable flow plus shutoff capability makes it useful for mixed plantings, seasonal changes, and DIY drip systems where individual control and low-pressure operation are priorities.
