Always rinse with fresh water after salt water exposure and inspect contacts periodically. The gold plating significantly extends contact life vs. bare copper or tin-plated alternatives.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: The connector feels loose after mating — what should I check?\u003c\/strong\u003e\u003cbr\u003eVerify the locking nut is fully tightened clockwise — firm, not just finger-tight. If the nut has already been tightened, check that the cable OD is within 4–6.5mm (undersized cables can cause ineffective sealing). Confirm the contact assembly is fully seated (should click into place). If threads are damaged, replace the connector set — never use a connector with compromised threads in a waterproof application.\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"max-width: 100%;\" alt=\"Firduo FD05 IP68 waterproof connector application scenarios eFoil marine outdoor\" src=\"https:\/\/cdn.shopifycdn.net\/s\/files\/1\/0227\/7805\/2685\/files\/4_-1_1024x1024.jpg?v=1599466314\"\u003e\u003c\/p\u003e","brand":"FIRDUO","offers":[{"title":"10A-2Core","offer_id":47615445106866,"sku":"FD05-10A-2C","price":3.6,"currency_code":"USD","in_stock":true},{"title":"10A-2Core*3","offer_id":47615445139634,"sku":"FD05-10A-2C-3","price":9.9,"currency_code":"USD","in_stock":true},{"title":"24A-1Core","offer_id":47615445172402,"sku":"FD05-24A-1C","price":3.9,"currency_code":"USD","in_stock":true},{"title":"24A-1Core*3","offer_id":47615445205170,"sku":"FD05-24A-1C-3","price":10.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/24A2.jpg?v=1782223790","url":"https:\/\/firduo.com\/products\/firduo-24a-waterproof-plug-socket-for-electric-hydrofoil-surfboard","provider":"Firduo","version":"1.0","type":"link"}
