UNSPSC 31402003: General insulation gasket

Insulation gasket act as an insulator between dissimilar metallic flanges. Also, they are used to isolate sections of pipework (dissimilar metals) electrically in the cathodic protection systems, thus preventing the electrostatic charge flow along the pipelines as they remove the possibility of galvanic cell system creation.

UNSPSC 31402003 General insulation gasket (Commodity) covers elastomeric sealing components that state and local utilities and municipalities procure for infrastructure systems, specifically gaskets rated for pressurized piping applications. The City of Tampa's recent RFQ for 16" field locking gaskets in EPDM material for ductile iron pipe demonstrates the operational scope: municipalities source these gaskets as replacement and maintenance components for water distribution systems, typically in small quantities as line-item procurements against estimated demand.

The recent activity shows municipal water and utilities departments as the primary buying constituency under this code. Geographic spread is limited in the recent record to Florida, with Tampa's June 2026 RFQ (26P00390, due June 18, 2026) seeking ten units of 16" EPDM locking gaskets as the sole recent solicitation in the source block. Gasket specifications are driven by pipe diameter and material compatibility (here, American DIP and EPDM elastomer); quote validity periods, FOB Destination shipping terms, and thirty-day payment cycles reflect standard municipal procurement practice for commodity-level water infrastructure components.
