G-FLS-D Female Locking Sleeve (2-Pin, 3-Pin, 4-Pin Female Connector )

G-FLS-D — G (2-, 3- and 4-contact) Locking Sleeve

The G-FLS-D is the G (2-, 3- and 4-contact) female locking sleeve for the RMG/RMK rubber-moulded diving connector family. It locks the mated pair together, carries the pressure seal of the assembly and provides strain relief for the pigtail. Standard material is Delrin (acetal); a stainless steel version (-S suffix) is available, together with high-pressure (HP, to 20,000 psi mated) and low-pressure (LP, to 4,000 psi) variants.

Key Design Features

• Locks the mated pair: retains the in-line connectors together and completes the pressure seal of the assembly.
• HP and LP variants: high-pressure sleeves are rated to 20,000 psi mated (approx. 13,000 m); low-pressure sleeves to 4,000 psi (approx. 2,700 m).
• Delrin or stainless steel: -D = Delrin (acetal) standard; -S = stainless steel for high-wear and corrosive service.
• Glove-friendly handling: knurled geometry sized for use with thick diving gloves.
• Correct fit by design: G size for 2/3/4-contact RMG connectors, K size for 5/6-contact RMK connectors — female and male versions matched to the connector gender.

Typical Applications

Locking and strain relief for mated RMG/RMK in-line connector pairs on diver umbilicals, helmets and masks, camera and lighting cables, and bell / saturation diving systems.

Notes for Selection

Always install the locking sleeve after mating. Select the sleeve size and gender to match the connector (G for RMG 2/3/4-contact, K for RMK 5/6-contact), and the HP or LP variant to match the working depth. Locking sleeves are supplied as separate line items and should be ordered per connector; matched pairs (female + male sleeve) are recommended for new umbilicals.
