MS3057-4C is the MS3057-C style waterproof cable clamp, the sealing accessory for MIL-DTL-5015 / SAE-AS50151 connectors. Unlike the MS3057-A clamp, which grips jacketed cable with two floating clamp halves, the C-style adds an internal neoprene gland compressed by a metal disc, so the cable entry is sealed against moisture as well as strain-relieved. It threads onto the connector accessory thread of shell sizes 10SL / 12S / 12 and accepts the MS3420-4A reduction bushing to close the gland down to smaller cables.
Wet, washdown and weather-exposed MIL-DTL-5015 harnesses: shipboard and dockside cable runs, ground support equipment, rail and heavy industrial machinery, outdoor junction boxes and any installation where the rear of the connector faces water ingress.
