Great info!

I've used a couple of these elbows before (from Farnell) they have G1/4 female threads, a large 11mm ID throughout and a slightly rounded bend although not as good as the swept copper elbow. With a G1/4 coupler, these can easily be mounted to a block or rad.



Something to keep in mind for those looking for elbow solutions.

Martin... PM me your mailing address and I'll send you one in the mail to test.

Cheers,
