The K-MLS-D is the Male Locking Sleeve for the RMK Series 5/6-pin commercial diving connector range. Locking sleeves are mandatory safety components that prevent accidental de-mating during all diving, deck handling, and transit operations. Must be engaged after every mating on a commercial diving spread.

Frequently Asked Questions
Q: Is a locking sleeve really necessary?
A: Yes - mandatory before every deployment. Cable tension and vibration can cause de-mating without it.
Q: Which connectors does K-MLS-D fit?
A: Fits all male (MLS) RMK 5/6-pin connectors.
Q: How to confirm engagement?
A: Audible click plus sleeve cannot be pulled rearward by hand.
Q: Replacement interval?
A: Every 50 mating cycles or annually - whichever first.
Q: Colour-coded options?
A: Yes - contact [email protected] with quantity and colour requirements.
Q: SS locking sleeves available?
A: Yes - 316 SS on request for high-abrasion environments.
Q: Need FLS and MLS on both connector halves?
A: Minimum one per mated pair; best practice is one on each connector half.
Q: Shelf life of unused sleeves?
A: POM has indefinite shelf life in normal storage. Stock spares for every connector.
Q: POM sleeve on rubber connector body?
A: Yes - fully compatible, no galvanic incompatibility in seawater service.
