MS90557 is the cable connecting receptacle of the Class L series and is built without a coupling ring — the mating half carries the coupling, which lets the joint sit tight against a cable gland or inside a confined space where a ring would foul. It is otherwise the same 600 V waterproof quick-disconnect body as the rest of the family.
