[PSUBS-MAILIST] Copper Washers...

[James Frankland <jamesf@guernseysubmarine.com>]

Hi All,

 

I've been working on some of my plumbing today and have come across something i think could be an issue.

 

Ive fitted 2 pressure gauges to read depth and also the variable tank.  These items have pipe adapters to connect them up.  The adapters are BSP parallel threads, sealed with a copper washer.  The one on the variable tank is a Swagelok adapter and the others are Parker fittings.  Both Parker and Swagelok told me to use copper washers.

 

But thinking about it, it seems like a bit of a daft idea.   Both pipes will have seawater running through them.  Copper\Stainless\Seawater.  Not a good idea?

 

Is this going to be an issue?  It doesnt sound right to me.  What else could\should I use as the seal?

Many thanks
