The IL8F is an 8-contact Circular series subsea in-line connector, female (sockets) face, wet-mateable and rated 10 A per contact at 7,000 m operational depth. It is factory moulded on a 2 ft (60 cm) chloroprene cable and couples through the characteristic locking sleeve, so the same part serves harness splices and hull penetrations.

Key Design Features
Wet-mateable: mate and demate in seawater; each contact carries its own moulded seal, so a single seal failure does not flood the connector.
SubConn Compatible: the same face geometry, contact pitch and 5/8-18 UNF-2A thread, so it retrofits existing panels and harnesses without re-machining.
Gold-plated contacts: brass UNS-C36000 contacts hold contact resistance below 0.01 Ω across the full 500-cycle life.
10 A per contact: rated current with a 50 A connector limit for the 8-contact shell.
Pressure qualified: 1,400 bar mated design depth, 800 bar open face; a PEEK shell extends service to 300 bar where weight matters.
Field serviceable: locking sleeves, O-rings and snap rings are replaceable; lead, thread and cable lengths can be specified to order.
