Polyethylene HDPE Water Pipe – SDR 11, 200 PSI | Built to Last Underground
When you're laying water line across a pasture, you need pipe that can handle pressure, resist the elements, and keep flowing for decades. The Polyethylene HDPE Water Pipe in SDR 11, 200 PSI is exactly that — a high-density polyethylene pipe built for underground water line installations on farms, ranches, and rural properties.
Rated at 200 PSI with an SDR 11 wall thickness, this pipe is engineered to handle the demands of agricultural water systems. HDPE is naturally resistant to corrosion, chemicals, and UV degradation, making it the go-to choice for buried water lines that need to perform year after year without maintenance headaches. The 500-foot coil gives you plenty of pipe to cover large pastures or multiple water points in a single order.
Flexible enough to handle ground movement and temperature changes, yet strong enough to hold pressure under load, HDPE pipe is the standard for a reason. Whether you're building a new water system from scratch or replacing aging galvanized or PVC lines, this is the pipe that gets the job done right.

| Philmac Joint Kit IPS-OD | Replacement nut and grab ring for remaking or servicing existing Philmac connections |
| Philmac PVC Grip Ring IPS-OD | Replacement grip ring for securing pipe in compression fitting body |
Common Applications
- Main Water Lines — Primary distribution from well, pump, or municipal source across ranch or farm
- Lateral Distribution Lines — Running water from mainline to individual troughs, tanks, and hydrants
- Pump-Fed Irrigation Systems — Pressure-rated for pump-fed agricultural irrigation
- Stock Tank Supply Lines — Long runs to remote water tanks and troughs
- Rural Water Distribution — Multi-property or subdivision water system laterals
Lay it once, forget about it — HDPE pipe is the underground water line solution built to outlast everything else on your farm.
