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

Keep every plant in your garden perfectly hydrated — no matter where it sits in the line. These 100-pack pressure compensating drip emitters deliver a consistent, constant-flow drip rate (2L/H, 4L/H, or 8L/H) regardless of inlet pressure fluctuations, so your potted herbs on the patio get just as much water as the ferns at the end of a long run.

Made in Mainland China.

Why Choose These Drip Emitters?

• Constant Output, Regardless of Pressure: Pressure compensating technology maintains a steady flow rate between 100 kPa and 350 kPa (1.5–4.0 bar), so every emitter in your system delivers the same amount of water — from the first plant to the last.
• Self-Cleaning Design: An innovative self-flushing mechanism activates each time the system shuts off, purging debris and preventing clogging before it starts. Less maintenance, more growing.
• Universal 1/4" Barb Fit: The standard barb thread connection fits most 4/7mm (1/4") drip irrigation tubing right out of the box — no special tools or adapters required. Easy DIY installation in minutes.
• 3 Flow Rate Options: Choose 2L/H for delicate seedlings and succulents, 4L/H for medium shrubs and vegetables, or 8L/H for thirsty trees and large planters. Each emitter delivers a true constant flow.
• Balanced Water Distribution: Ideal for long branch lines, sloped gardens, green walls, and systems where pressure variation is a real challenge. Every plant gets its fair share of water, every time.
• Durable High-Quality Plastic: UV-resistant and built to withstand extended outdoor use season after season.
• 100-Pack Value: Stock up and outfit your entire drip irrigation system at once — perfect for market gardens, raised beds, or extensive patio setups.

Frequently Asked Questions

Q: What is the difference between a pressure compensating drip emitter and a standard dripper?

A: A standard dripper's flow rate changes as water pressure rises or falls — you can end up overwatering plants near the pump and underwatering those at the end of the line. A pressure compensating drip emitter uses an internal diaphragm to automatically regulate flow, delivering the same constant rate (2L/H, 4L/H, or 8L/H) throughout the operating pressure range of 1.5–4.0 bar. This makes them ideal for hilly terrain, long branch lines, or any system where pressure is uneven.

Q: What tubing size do these drip emitters fit?

A: These emitters are designed for standard 4/7mm (approximately 1/4 inch) drip irrigation tubing with a barb thread connection. They are compatible with most common drip irrigation systems and require no special tools for installation — simply push and lock into your tubing.

Q: How does the self-cleaning mechanism work?

A: When your irrigation system shuts off and pressure drops below the operating threshold, the internal diaphragm opens fully, allowing any trapped debris or sediment to flush out. This automatic self-cleaning cycle helps prevent clogging over time, reducing the need for manual cleaning and keeping your drip system running smoothly.

Q: Which flow rate should I choose — 2L/H, 4L/H, or 8L/H?

A: The right flow rate depends on your plants' water needs and soil type. As a general guide: 2L/H suits low-water plants like succulents, herbs, and seedlings; 4L/H works well for most vegetables, shrubs, and medium-sized perennials; 8L/H is best for large potted plants, trees, and thirsty crops. You can also mix flow rates in the same system since the pressure compensating feature ensures each emitter delivers its rated flow independently.
