Adjustable Sprinkler Head Assembly

The USDA Forest Service Rocky Mountain Area Incident Support Cache intends to solicit an estimated quantity of Adjustable Sprinkler Head Assembly units (NFES 0998) for use during prescribed burns and wildfire incidents, with a sources sought notice response due June 5, 2026. This procurement is set aside for total small business.

The assembly consists of three integrated components: a full or part-circle adjustable solid brass or bronze impact sprinkler head with stainless steel springs and 1/2" MNPT inlet; a 45-degree angle elbow body constructed from cast aluminum alloy (356-T6) with maximum 4.0-inch overall length designed to secure to a 1" x 1" steel stake; and a brass swivel reducing fitting (3/4" FHT x 1/2" FNPT) with rubber gasket. The sprinkler head must operate at 30–50 PSI with nominal flow rate of 3.0–5.5 GPM, rotation capability of 20–340 degrees in part-circle mode or full-circle operation, spray radius of 30–45 feet, and spray trajectory of 25 degrees. All metal components must be free from defects with symmetrical and concentric tolerances to 0.030 inch, and the elbow body must withstand 600 psi hydrostatic proof pressure without leakage or deformation. Units must be packaged twenty per carton in 10"x8"x6" single-wall corrugated fiberboard boxes with 200 psi bursting strength and 32 lbs ECT rating.

Performance location is the Rocky Mountain Incident Support Cache in Lakewood, Colorado. NFES 0998 is a new item being added to the National Fire Equipment System Catalog and may replace the current non-adjustable Sprinkler Head Assembly NFES 0999 in Water Handling Kit 1048. Responses to the sources sought notice must be submitted by 5:00 p.m. Eastern Standard Time on June 5, 2026, to shannon.meadows@usda.gov, limited to twenty pages, and must include SAM UEID registration details, past performance, and capability statement.
