UNSPSC 40174008: PVC pipe slipon flange

UNSPSC 40174008 PVC pipe slip-on flange is a Commodity code representing individual pipe fittings and components used in gravity-fed sewer and water infrastructure replacement and repair. State and local governments procure these products as part of large sanitary sewer rehabilitation and mainline extension projects where PVC piping replaces older vitrified clay pipe (VCP) and cast iron systems. The work captured under this code spans removal and replacement of service connection fittings, lateral extensions, and mainline point repairs within municipal water and sanitation districts. Issuing bodies include county sanitation districts and county public works departments conducting infrastructure rehabilitation in unincorporated areas and municipal corridors.

Santa Clara County is the dominant recent buyer under this code, issuing multiple infrastructure rehabilitation solicitations in 2026. County Sanitation District No. 2-3 posted an IFB (ITBRDAFY270088) on August 26, 2026 with a September 17, 2026 deadline for its Structural Defect Repair Project Phase 2, which includes removal and replacement of twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes, along with 6-inch PVC SDR26 service laterals totaling approximately 47 linear feet across two mainline extensions in the unincorporated eastern foothills. A second Santa Clara County IFB (ITBRDAFY260694) posted April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, with bids due May 21, 2026, included removal and replacement of inductive traffic loops and other infrastructure components potentially incorporating PVC fittings, though the opportunity summary does not itemize slip-on flanges or wyes by quantity. Geographic activity is concentrated in Santa Clara County, California.
