It seals the plug's mating face when unmated, keeping dust and moisture out of the contacts. The cover is molded from chloroprene rubber (CR), a material chosen for its flexibility and resistance to weather, ozone, and mild oils — the same stuff used in wet-location cable boots and gaskets. It comes in black and includes a strap with a ring that tethers the cap to the cable or panel so it doesn't wander off during service. ## Sealing and Retention — What You Get The cap is listed as both dust tight and waterproof, which means it forms a seal against the plug's housing that keeps out splashing water and airborne grit. In a wet or dirty environment — think outdoor machinery, marine electronics, or washdown areas — that seal is the difference between a connector that clicks together cleanly next season and one that's corroded solid. The strap and ring are a practical field detail: loop the ring around the cable or a nearby bracket, and the cap stays within arm's reach when the plug is mated. No hunting for a lost cover in the mud. ## Fits Which Connectors This cap is designed for HR30 series plugs with shell size 7. The matching receptacle-side cap is the HR30-7R-C(31). If you're working with shell size 8 plugs, the cap to grab is the HR30-8P-C(31). Same material, same sealing, same strap — just a different fit diameter. The shell size is stamped on the connector body, so match that number before ordering.","metaTitle":"HR30-7P-C(31) Cap Cover, Black, Dust Tight Waterproof","metaDescription":"HR30-7P-C(31) black chloroprene rubber cap cover for HR30 series plugs.
