UNSPSC 40173300: Pipe nipples

UNSPSC 40173300 Pipe nipples is a Class code that covers small-diameter threaded or flanged pipe connectors and stub sections used in plumbing, mechanical, and utility infrastructure. State and local governments procure pipe nipples primarily as materials embedded in larger infrastructure projects rather than as standalone line items — they appear in sewer rehabilitation, water system upgrades, and building mechanical systems where short connecting segments between fittings, valves, and main runs are required. The issuing bodies are predominantly county sanitation districts, county public works departments, and county transportation authorities executing infrastructure rehabilitation and new-construction projects.

Santa Clara County dominates recent activity under this code, with two major infrastructure projects posted in 2026. County Sanitation District No. 2-3 issued an ITB (ITBRDAFY270088) on August 26, 2026 for the Structural Defect Repair Project Phase 2, due September 17, 2026, which includes removal and replacement of service connection fittings—specifically twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes—alongside extensive PVC and HDPE mainline pipe work in unincorporated eastern Santa Clara County. Santa Clara County itself posted an ITB (ITBRDAFY260694) on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, which encompasses pavement rehabilitation, curb and gutter installation, and supporting infrastructure improvements; while the primary scope centers on asphalt and concrete work, the project specification incorporates materials and connections typical of utility stub work. Both projects require physical bid delivery to the County Government Center in San Jose and carry tight completion timelines of 65 and 142 working days respectively. Geographic activity is concentrated in California, specifically the Santa Clara County area, with no evidence of solicitations in other states in the recent-opportunities block.
