The NuArc came with a bleed valve, but I had another vacuum frame in the
darkroom that didn't... I bought a bleed valve -- um, trying to remember,
it was 8-10 years ago -- at an industrial type hardware store, on Canal
Street, as it happens, probably about $20, and sainted husband simply cut
the tube & inserted. As I recall the Nuarc company also sold bleed valves
for about twice the price.
