[PSUBS-MAILIST] SubConn BH4F and IL4M Connectors

Wed Apr 10 13:19:34 EDT 2019

Subconn is only at 12 weeks? It was 18 last I asked. Seaconn quoted 26!
Teledyne underwater cable company is asking for a $1200 minimum order PER
LINE ITEM.

Wet matable circular connectors were invented in the 1960s for Trieste 2.
Most companies connectors are actually interchangeable, because they are
mostly copies of the Trieste connector. You would think they would be
commoditized  and readily available by now. Or that the manufacturers would
atleast stock common sizes, instead of doing custom everything.

I have been looking at these on ebay. I haven't purchased or tested any, so
I cant vouch for the reliability. They also only sell connectors, not the
cable assemblies. You could purchase 2 bulkhead ends, wire them to a wiring
harness, then connect the bulkheads with oil filled vinyl tubing and hose
clamps. That's standard practice with ROV's but messy and not 100%
reliable. They typically sell connectors with barbed ends for that purpose,
although im willing to be the threaded ends would work with a stretchy
enough hose.
