A-411-HB

A-411-HB bleed down valve. Very similar to a 1/4" bleeder valve but with a hose barb on it so you can attach a 3/8” hose to it and run the hose to another location so when you open the valve the ammonia vents in a remote location. Great for bleeding nurse tank connections and heat exchanger. Run the hose to the back of the nurse wagon or applicator and vent the ammonia away from you.
