Hammond 1487BS 2.5x2.5 Wireway Flange Gasket and Screws

The 1487BS is the Gasket & Screws kit for 2.5 x 2.5 wireway in the 1487 Series Type 12 pull through wireway system. In this system, solid oil resistant gaskets are used between flanges when sections and fittings are bolted together, and this part supplies that gasket with its screws for the smallest wireway size.

The gasket is made from 465 solid neoprene, black. Per the drawing it is a 3.88 in square frame with a 2.44 in square inside opening, 0.13 in thick, with eight 0.28 in bolt holes around the flange face. The part page lists the package size as 3.88 in x 3.88 in x 1 in (99 mm x 99 mm x 25 mm).

Buyers typically order it to seal a flanged joint between 2.5 x 2.5 sections, elbows, tees and other fittings, or to replace a gasket at a joint that has been opened. The series notes that one gasket kit, complete with hardware, is provided with each straight section or fitting, so this separate part covers extra or replacement joints.

The 1487 Series ordering table marks the Gasket & Screws parts with footnote ¹, "Does not meet CSA or UL requirements"; the part page also lists UL File E186830 and CSA Cert. LL21312. The part is REACH and RoHS compliant, carries UNSPSC 39131710, and ships at 1 lb (0.45 kg).
