20 Variflow rodent water valves for $45 delivered

I am re-doing some of my rodent racks and now have 20 used variflow rodent water valves available for sale for $45. delivered. Most of these have new or newer diaphragms and /or o-rings.

Update : As of 12/27 these valves have been sold. I might have about 20 or so more available in a week or so.

Thanks
