Vintage NOS Dacor double hose regulator duckbill exhaust valves

Description

Rare, nearly impossible to find original Dacor duckbill exhaust valves. NOS, packed in talc. Perfect condition, supple and dry.
These are perfect for restoring the C-2, C-3, and C3N to OEM, and for replacing the also nearly impossible to find exhaust diaphragm in Dacor two diaphragm, double hose regulators with an OEM part. The manufacturer abandoned the second diaphragm as soon as Cousteau's patent of the duckbill valve expired, and used them in the later regulators.
These can be installed in the R-1,2,3 (2500 series) and the R-4, and will improve the exhaust effort over the original small mushroom exhaust valve. These are better and much less expensive!
