100-Pack Pressure Compensating Drip Emitters 2L/4L/8L

Keep Every Plant Perfectly Watered — No Matter the Pressure

Tired of uneven watering across your garden? The Shunmaii 100-Pack Pressure Compensating Drip Emitters deliver a precise, consistent flow to every plant — whether it's the first pot on your line or the last. With selectable flow rates of 2L/H, 4L/H, or 8L/H, these premium micro drippers are the backbone of a reliable, water-efficient irrigation system.

Made in Mainland China.

Why These Drip Emitters Stand Out

• True Pressure Compensation: Maintains a constant output flow rate across inlet pressures from 100 kPa to 350 kPa (1.5–4.0 bar). No more over-watering near the source or dry spots at the end of the line.
• Self-Cleaning Design: A built-in self-cleaning mechanism flushes debris on every cycle, keeping emitters clog-free and your irrigation running smoothly season after season.
• Universal 1/4" Barb Connection: Fits standard 4/7 mm drip tubing. Snap into your existing system in seconds — no special tools required.
• Balanced Water Distribution: Ideal for long tubing runs, green walls, raised beds, and potted plant arrays where pressure drop is a real concern.
• High-Quality Plastic Construction: UV-resistant, durable plastic built to withstand outdoor conditions year-round.

Frequently Asked Questions

Q: What flow rates are available for these drip irrigation emitters?

A: These pressure compensating drip emitters are available in three constant flow rate options: 2 L/H, 4 L/H, and 8 L/H. You can select the flow rate that best suits your plants' watering needs when ordering.

Q: What tubing size do these drip emitters connect to?

A: These emitters feature a universal 1/4" barb thread that connects to standard 4/7 mm drip irrigation tubing, making them compatible with most existing residential and commercial drip irrigation systems.

Q: How do pressure compensating drip emitters differ from standard drippers?

A: Unlike standard drippers whose output varies with water pressure, pressure compensating emitters use an internal diaphragm to regulate flow and deliver a consistent drip rate regardless of pressure fluctuations between 1.5–4.0 bar. This is especially valuable for sloped gardens or long tubing runs where pressure may drop significantly.

Q: How do I prevent these drip emitters from clogging?

A: These emitters feature a built-in self-cleaning mechanism that automatically flushes sediment and debris at the start and end of each watering cycle. For best results, use them with a filter at the water source and periodically check your irrigation lines for buildup.
