The Irritec P1 15 Mil Drip Tape (1000' Roll) is widely considered one of the highest quality drip irrigation tapes on the market today. Engineered for serious agricultural row crops, large market farms, and sprawling raised beds, the Irritec P1 features a revolutionary seamless construction. Traditional drip tapes are often manufactured with a bonded seam running down the length of the tubing, which can create a weak point that leaks when stretched over standard 5/8" tape fittings. Irritec's seamless extrusion completely eliminates this issue, offering unmatched reliability and a perfectly watertight seal at every connection point.
This robust 15 mil thickness is the heavy-duty standard for multi-season use, providing excellent resistance against field abrasion and insect damage. Inside the seamless tube, precise, discrete emitters are pre-installed every 8 inches, delivering a high-volume flow of 40 GPH per 100 feet. This ensures incredibly uniform and consistent moisture distribution across long lateral runs up to 460 feet. Designed to operate strictly between 10 and 15 PSI, the Irritec P1 performs beautifully whether laid above ground, buried shallowly, or installed underneath protective plastic mulch.

Install your Irritec P1 Drip Tape quickly and correctly.
Step 1: Regulate Your Pressure
Irritec P1 operates strictly between 10 and 15 PSI. Ensure your head assembly includes a low-flow pressure regulator (10 PSI or 12 PSI) and a minimum 155-mesh filter.
Step 2: Roll Out the Tape
Unroll the tape down your crop row. If the tape has colored installation stripes, ensure they are facing UP towards the sky. This ensures the internal discrete emitters are positioned correctly to prevent sediment from settling over the outlets.
Step 3: Connect to Mainline
Punch a hole in your poly mainline or Oval Hose header. Insert a standard 5/8" tape takeoff fitting. Slide the seamless drip tape over the barb and twist the locking nut over the tape to secure it. You will immediately notice how tightly the seamless wall grips the barb.
Step 4: Flush and Cap
Before capping the system, turn the water on to flush any dirt out of the open rows. Once the water runs clear, terminate the end of each row by folding it over and slipping on a standard 5/8" tape end closure.
Why is seamless construction better?
Most drip tapes are manufactured by folding a flat sheet of plastic and gluing the seam. When you stretch this seam over a round plastic fitting, the seam creates a tiny gap or crease that can leak water.
Irritec P1 is extruded as a single, perfectly round, seamless tube. This means it stretches evenly and uniformly over standard 5/8" fittings, virtually eliminating any chance of leaks at your connection points.
Do I need to use a pressure regulator?
Yes, an irrigation pressure regulator is absolutely mandatory. This tape is designed to operate strictly between 10 and 15 PSI.
Standard home and farm water pressure is much higher (40-60+ PSI), which will immediately rupture and blow out the thin-walled tape. We recommend a 10 PSI or 12 PSI regulator.
How long does 15 mil tape typically last?
15 mil is the heavy-duty standard for agricultural tape, making it highly durable for multi-season use. It can easily last for several years with proper care.
You can significantly increase its lifespan by burying it shallowly or covering it with mulch to protect it from UV rays, farm machinery, and animals.
How should I prepare my drip tape for spring planting?
Because 15 mil is heavy-duty tape, it is excellent for reuse. Before running water to your new crops, open the end closures and thoroughly flush the lines.
Check for any rodent or insect damage from the winter. Small holes can easily be patched using a standard 5/8" tape coupler before you pressurize the system for the spring season.
