The 3/4" Polyethylene Mainline Tubing is the professional standard for high-flow irrigation systems, popular for larger home gardens, orchards, and small farms. Designed to handle significantly more volume than standard 1/2" tubing, this supply pipe is ideal for use as a primary header line or a branch line off a larger water source. To protect your system and ensure consistent flow, we recommend installing this downstream from a high-quality pressure regulator.
Commonly referred to as distribution pipe or drip hose, this durable poly tubing maintains excellent water pressure even over long runs. Its 0.820" inside diameter allows for a maximum flow of 480 GPH, providing the capacity needed for multiple zones or high-flow emitters. This tubing is designed to work seamlessly with various irrigation fittings, including Easy Loc, compression, and barbed styles, ensuring a secure and leak-proof installation. Available in 100', 250', and 500' rolls, you can choose the exact length required for your project.
Understanding exact dimensions is critical for selecting compatible fittings.

Follow these steps for a successful high-flow mainline setup.
Step 1: Layout
Unroll the tubing and let it sit in the sun for 20-30 minutes. This softens the poly, making it much easier to straighten and work with during installation.
Step 2: Cutting
Use a tubing cutter to ensure a clean, square cut. This is vital for a leak-proof seal, especially when using compression or Easy Loc fittings.
Step 3: Connecting Fittings
If using Easy Loc fittings, rotate the locking nut back, push the tubing over the barb until seated, and twist the nut forward to lock. For compression fittings, push the tubing firmly into the socket with a rocking motion.
Step 4: Securing the Line
Use hold down stakes every 5 to 10 feet to keep the mainline in place and prevent it from shifting due to temperature changes or water pressure.
