Consistent, Clog-Free Drip Irrigation — Every Time

Keep your garden, lawn, potted plants, or green wall perfectly watered with Shunmaii's 100-Pack Pressure Compensating Drip Emitters. Engineered for precision, these drip emitters deliver a steady, reliable flow rate regardless of pressure fluctuations — so every plant in your system gets exactly the water it needs, no matter how long your tubing runs.

Made in Mainland China.

Key Features

• True Pressure Compensation: Maintains a constant output flow rate across inlet pressures from 100 kPa to 350 kPa (1.5–4.0 bar). Choose from 2 L/H, 4 L/H, or 8 L/H to match your plants' needs.
• Self-Cleaning Mechanism: Built-in self-flushing design actively prevents clogging, keeping your irrigation system running smoothly with minimal maintenance.
• Universal 1/4" Barb Thread Connection: Fits standard 4/7 mm drip irrigation tubing. No special tools required — simply push and connect to your existing system.
• Balanced Water Distribution: Ideal for long branch lines or setups with significant elevation changes where pressure drop is a common challenge.
• Versatile Applications: Perfect for garden beds, container plants, raised planters, green walls, and drip irrigation systems of all sizes.
• Durable High-Quality Plastic: Lightweight yet tough construction resists UV exposure and outdoor conditions for season-long reliability.

Frequently Asked Questions

Q: What pressure range do these pressure compensating drip emitters support?

A: These drip emitters are designed to work reliably within an inlet pressure range of 1.5 to 4.0 bar (100–350 kPa). Within this range, the flow rate remains constant — 2 L/H, 4 L/H, or 8 L/H depending on the variant you select — regardless of pressure fluctuations in your irrigation line.

Q: What size tubing do these drip emitters fit?

A: Each emitter uses a universal 1/4" barb thread connection compatible with standard 4/7 mm drip irrigation hose/tubing. They are designed for tool-free installation and work with most popular drip irrigation systems on the market.

Q: How does the self-cleaning feature work?

A: The self-cleaning mechanism activates during pressure fluctuations — particularly when the system starts up or shuts down. The internal diaphragm opens slightly to flush out particles and mineral deposits before settling into regulated flow, significantly reducing the risk of clogging over time.

Q: Can these emitters be used for potted plants and indoor green walls?

A: Yes! These pressure compensating drip emitters are ideal for potted plants, container gardens, and vertical green wall irrigation systems. Their ability to maintain a consistent flow rate even over long tubing runs or across varying elevations makes them perfect for these applications where even water distribution is critical.
