Ralston Instruments Differential Pressure Transmitter Test Fittings
Connect a Quick-test hose directly to a DP transmitter or gauge valve using the bleeder port when the transmitter is not mounted on a 3 valve manifold or gauge valve or when the manifold is not easily accessible.
This unique fitting makes a metal to metal seat on the transmitter or gauge valve and a Quick-test hose can be attached on the other side.
Connects through the bleeder screw port on a DP transmitter. Made in USA
