In Need Of An Inline Waterproof 2 Pin Connector

[2slowtogofast]

I have a compression fitting that I am using to bring power into a pressurized vessel. On the side exposed to the enviornment there are 2 14 AWG 24" long leads. This vessel is going to be under water. So I need a way of creating a waterproof connection to each of the 24" leads so I can have a longer cable that I can run up and out of the water to a 24V DC power supply. Does anybody know of something that could possibly help me. Thanks.

See http://www.dsmt.com/resources/ip-rating-chart for the "ingress protection" codes for connectors.

Presumably you need connectors rated as IPx7 or IPx8 (where the x digit specifies the protection against solid objects) depending on the water depth.

Yes I think I would need IP08. I have tried searching but have not found much. Is there a small inline connector that could meet these requirements.

Digikey has 1,329 dustproof and waterproof circular connectors which are in stock. Each item has a link to a data sheet with more info. I took a look at one that claimed the connector was tested at a depth of 10m for 2 weeks and 100m for 12 hours.

There are many other kinds of connectors if a circular one will not work for your device.

edit: I filtered the search for 2-pole plugs as well as waterproofing. There are many more possibilities for the circular connectors.

Is this a hobby or manufacturing application?

I'd take a look at Deutsch DT series

they work well on outboard motors even after a day underneath salt water.

Maybe you didn't find much searching for IP08 because if it's waterproof it's also dustproof. That would make it IP68. I googled "IP68 connectors" and there were many to choose from.

Also, you can get some dielectric grease from a hardware store with a good electrical section. If you squeeze some into any connector it will help keep the water out.

There are IP58s as well, for connectors that are normally used dry but might get dropped in water - e.g. cellphones etc.
