ABSTRACT:
A fluid test device having a manifold formed of elements machined from rod stock for high accuracy. The manifold defines open end portions to which are sealingly secured a pair of manifold valves having front operated handles. The manifold includes a threaded hanger recess for mounting of the device to a hanger or housing. The manifold and attached valves may be disposed within a snap-on cover having a back portion coplanar with the gauges connected to the valves to provide a stable, flat back surface to the device. The cover may be snapped on to protect the brazed connection after all of the testing of the device is completed. The valves and manifold are arranged to have a coplanar surface to provide automatic alignment relative to a common plane, permitting facilitated brazing of the valves to the manifold connectors.
