Flexible Irrigation Pipe 1/2" D X 100' ft. L Polyethylene Black - Orbit 38931 Pro-Blend Riser The Orbit 38931 Pro-Blend irrigation riser flex pipe is a 1/2 inch x 100-foot roll of black linear low-density polyethylene (LDPE) swing pipe designed for reliable, flexible connections between sprinkler lateral lines and spray heads, gear-drive rotors, or impact sprinklers. Engineered for durability and ease of use, this riser flex pipe provides a kink-resistant, watertight solution for residential and commercial irrigation systems. Constructed from high-quality LDPE, the pipe offers excellent flexibility, making it easy to route around obstacles and terrain variations without cracking or breaking. Its textured outer surface ensures a secure grip when installing spiral barb fittings, allowing for quick, tool-free assembly by threading fittings directly into the pipe. The 0.085 inch nominal wall thickness and 120 psi maximum pressure rating provide strong performance under standard irrigation conditions. Compatible with a wide range of fittings, the Orbit 38931 works seamlessly with Funny Pipe fittings from Toro, as well as 1/2-inch swing fittings from Rain Bird and Hunter. For use with Blu-Lock push-fit systems, a 1/2-inch Blu-Lock x Spiral Barb Adapter is required. This versatility makes it ideal for system upgrades, repairs, or new installations across multiple brand platforms. Designed specifically for non-constant pressure outdoor irrigation applications, this pipe should only be used with cold water and must be drained before freezing temperatures to prevent damage. It is not intended for constant-pressure or potable water supply lines. Weighing 5.74 pounds and coiled for compact storage, the 100-foot length provides ample coverage for multiple sprinkler zones or extended runs. Packaged in a 17" x 17" format, it?s easy to transport and store.
