Molded Access Cover with Sealing Plug and Oval Profiles, Raised Rim, Recessed Boss

Elastomer compound selection determines whether a moulded sealing plug retains its performance after thermal cycling and chemical exposure; EPDM handles steam, ozone, and brake fluid for automotive and hydropower applications, while NBR suits oil and fuel contact in motorcycle and machinery sealing plug applications. Plug OD-to-housing bore fit also governs retention: OD below the interference specification allows the plug to back out of the bore under pressure cycling.
