Durable polyethylene cut-off riser designed for irrigation and landscape plumbing. The M481-005 provides a 1/2 in. x 6 in. length with male pipe threads (MPT), and a multi-section cut-off design so installers can trim to the exact height needed on-site.

  • Material: High-density polyethylene for long-lasting corrosion resistance and flexible performance in buried or exposed installations.
  • Adjustable length: Four-in-one cut-off design allows quick trimming to common lengths—reduces inventory and speeds job completion.
  • Thread type: Standard MPT (male pipe thread) for reliable connection to industry fittings and sprinkler heads.
  • Size: 1/2 in. nominal diameter and 6 in. overall length before trimming.
  • Applications: Ideal for irrigation lateral lines, sprinkler risers, and general landscape water distribution systems.
  • Installation tips: Use standard thread sealant, hand-start threads, then tighten with appropriate tool; avoid over-tightening to protect threads.

This simple, versatile poly riser is a practical choice for contractors and homeowners who need a reliable, trim-to-fit solution for sprinkler and irrigation connections. Keep a pack on the truck to save time and reduce part counts on the job.
