3/16 (.187) NEOPRENE CLOSED CELL SPONGE

Use item 0287187 when a Neoprene 70A O-Ring Cord is required for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.187 inch (4.75 mm) cross section, with 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The neoprene (chloroprene) construction supports moderate oil resistance, ozone resistance and weathering performance in general-purpose industrial service. The black color and round profile provide a practical visual identifier during receiving, stocking and installation. As O-ring cord, it gives fabricators flexibility to cut and splice seals when a molded size is not practical or available. It is sold as cord stock, making it useful for fabricating custom O-rings or replacement seals in nonstandard diameters. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims. Engineers, maintenance teams and purchasing groups can use the listed dimensions to verify fit before selecting the seal for a groove or assembly. The material and durometer details also help narrow performance expectations for compression, flexibility, extrusion resistance and service compatibility.
