No worries. I did end up ordering that pack of elbows from Grainger and it is a perfect fit. 4mm Metal Swivel Elbow, 90 Degrees
However this part is nickel plated brass which is not NSF rated. Since it's such a small portion of water in my daily intake I'm not too worried about it but will eventually find a stainless option - probably whenever manufacturers' supplies get back to normal. Until then - enjoying no leaks! On Tue, Aug 10, 2021, 5:59 PM Wilson007 <[email protected]> wrote: > Sorry, I haven't been checking this thread.
