UNSPSC 20121127: Landing collar

A component installed near the bottom of the casing string

UNSPSC 20121127 Landing collar is a Commodity code covering a specialized fitting used in mechanical and fluid-handling systems, though state and local government procurement under this code shows minimal recent activity. Landing collars function as positioning or sealing components in piping assemblies, hydraulic systems, and equipment where precise alignment or pressure containment is required. The code captures a narrow product line within broader mechanical fastening and fitting families, and state and local buyers—typically maintenance and operations departments at municipalities, transit authorities, water districts, and county facilities—source these components as replacement parts or components within larger equipment orders rather than as standalone procurement initiatives.

No recent state and local contract opportunities are available in the source material for this code. The Commodity's narrow technical scope and its status as a component part rather than a standalone product or service line may account for limited visibility in public procurement notices, as such items often flow through master equipment contracts, cooperative purchasing agreements for maintenance supplies, or subordinate line items within larger facility or vehicle acquisition projects rather than appearing as independent solicitations.
