Orbit 37227 Cut Off Riser 0.5x6 Inch Irrigation Riser

Product Description

The ORBIT IRRIGATION PRODUCTS INC 37227 is a 1/2-inch by 6-inch cut-off riser designed for use in residential and commercial irrigation systems. Molded from high-grade black polyethylene, this riser connects sprinkler heads to lateral supply lines and allows installers to cut the riser down to a needed length, from 1 inch up to 6 inches in 1-inch increments. Full ASTM standard threads ensure a secure, leak-resistant fit with compatible fittings and sprinkler heads. At 0.02 pounds, it is lightweight and easy to handle during installation. Irrigation professionals and landscapers rely on this type of adjustable riser to dial in the correct sprinkler height for turf, ground cover, and shrub zones.

This riser is suited for residential lawn and garden irrigation as well as light commercial landscape applications. It installs between the threaded lateral outlet or fitting and the base of the sprinkler head. The cut-off design gives technicians flexibility when working in areas where a fixed-height riser would leave the head sitting too high or too low relative to grade. Typical applications include pop-up spray zones, rotor zones, and shrub-head installations where head height must be adjusted to clear mulch, turf, or hardscape edges.

Installation Notes

Installation is performed by irrigation technicians or licensed landscaping professionals. Shut off the irrigation system and relieve line pressure before removing or installing risers. Hand-tighten the riser into the fitting or sprinkler head, then snug with appropriate pliers or a riser wrench — avoid overtightening polyethylene threads. Cut the riser to the desired length using a sharp utility knife or riser cutter before threading into place.
