Advantage of custom rubber gaskets

Custom gaskets are cut or molded to a joint that a catalog washer will not seal. The live article lists temperature resistance, UV and ozone resistance, exact geometry with tabs or holes, low compression set, and low sealing force for plastic or glass flanges.

Some listings mention food-contact or electrically conductive compounds. Those claims sit on the product pages; certificate files are not published on the site, so treat them as items to confirm with the supplier.
