Stenner MLDBINJ Injection Check Valve 1/4" Connection with Santoprene Duck Bill

Package of 5 each. 

This Injection Back Check Valve has been redesigned to work with low pressure pumps rated for 0 to 25 PSI maximum. The newly designed low pressure "Duck Bill" check valve only requires 4 - 6 PSI to fully close the check valve preventing fluids from back feeding into the pump and possibly overflowing the chemical resevoir.
