The Netafim Self-Piercing 0.5 GPH Drip Emitter (Blue) is engineered to deliver a slow, highly controlled drip, making it the perfect solution for dense soils, delicate container plants, and precision agricultural applications. Utilizing advanced pressure-compensating technology, these emitters guarantee a consistent output of exactly 0.5 gallons per hour, regardless of elevation changes or pressure fluctuations between 10.15 and 58 PSI.
Designed for unparalleled ease of use, these emitters feature a rugged, self-piercing inlet barb. This allows you to press the emitter firmly into your 1/2" Mainline Tubing without requiring a separate hole punch tool. Once installed, simply attach 1/4" micro-tubing to the top outlet barb to route the water directly to your plant's root zone, virtually eliminating runoff and evaporation.

Follow these easy steps to install your Netafim self-piercing emitters.
Step 1: Pierce the Mainline
Take the pointed base inlet barb of the blue emitter and press it firmly and directly into the wall of your 1/2" or 3/4" polyethylene mainline tubing until it pops securely into place.
Step 2: Attach the Micro-Tubing
Push one end of your 1/4" micro-tubing onto the exposed top outlet barb of the emitter.
Step 3: Route to the Plant
Run the micro-tubing directly to the base of your plant, shrub, or into your planter box. Secure the end of the tubing near the root zone with a wire hold-down stake.
What type of soil is best suited for a 0.5 GPH emitter?
The slow 0.5 GPH flow rate is perfect for heavy or clay-based soils. It allows the water to soak deeply into the ground rather than pooling on the surface and running off.
What does "self-piercing" mean for installation?
It means the emitter's inlet barb is sharp and strong enough to puncture polyethylene mainline tubing directly. This allows you to install the emitter securely without needing a separate hole punch tool.
Does the water flow change if my water pressure fluctuates?
No, these Netafim emitters are pressure-compensating. As long as your system operates between 10.15 and 58 PSI, they will deliver a highly accurate and consistent 0.5 gallon per hour to every plant.
What size micro-tubing should I use with the blue Netafim emitter?
The top outlet barb perfectly fits standard 0.160-inch ID by 0.220-inch OD micro-tubing. This allows you to route the slow, consistent drip directly from the mainline emitter to the specific root zone.
As mid-May rain subsides and the soil hardens, why is the 0.5 GPH emitter crucial for prepping my clay soil for summer?
As clay soil dries out in mid-May, it becomes highly resistant to rapid watering, causing severe runoff. The slow 0.5 GPH drip guarantees that water penetrates the hardening soil crust, encouraging deep root growth before the extreme summer heat hits.
Deep, well-established roots are your plants' best defense against the coming summer drought conditions. Setting up this slow-soak system now is essential for long-term plant health.
