The problem with those Dowty washers is that they're not metal so they don't last. I tried those years ago and am of the opinion that they're crap.

When I bleed my brakes I have a 3 foot long piece of vinyl hose and a gallon jug half filled with water.  Stick one end of the hose into the jug and down into the handle. 

The hose will stay in there and won't easily pop out dripping brake fluid everywhere.  The water in the jug makes it very stable so it won't tip over.  The water also dilutes the brake fluid to make it a little less nasty

Ha! Something we don't agree on for once . I've had Dowty washers on LFB's hydraulics for the last nine years and 62,000 miles without any problems. Just a thought; maybe the ones you got were not certified for hydraulic fittings? I can't see you making that mistake though.

Maybe the ones I got were just cheap ones but they didn't hold up at all.  There were sold as being for vehicle brakes though.

The Dowty washers for brake lines also need certification for polyglycol usage and those are being used by Dai, probably.  See attached Potter Associates chart.
