UCC UC-DC 42S Flexible Drive Coupling Sleeve Nylon Insert - New (NOS)

UCC UC-DC 42S flexible drive coupling sleeve — the internally splined nylon element that transmits drive between two toothed coupling hubs, as used in UCC-style pump drive and shaft-to-shaft couplings on marine, industrial, and plant equipment.

Application: The part number UC-DC 42S is printed on the original UCC packaging and the UCC logo is molded into the sleeve. Specific engine, transmission, or vessel application is not verified — this sleeve must be matched to your existing coupling hubs by tooth count, spline size, outside diameter, and overall length.

Condition: New / NOS. No tooth wear, no deformation, no evidence of having been run. Light handling scuffs and shop dust only. Original packaging is aged, soiled, and torn. Sleeve only — no hubs or hardware included.

Approximate dimensions taken from the photos: about 3.5 in outside diameter and about 2.2 in long. Confirm against your coupling before ordering.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.
