  • Adaptor for mounting a filter to a hydraulic manifold
    Patent number: 11806649
    Abstract: A filter adaptor joins a canister filter to a hydraulic manifold block. The adaptor includes a hexagonal tool-receiving portion, an outflow passageway and one or more inflow passageways. The outlet flow passageway extends between opposed ends of the adaptor, and is used to direct filtered fluid from the filter to the manifold block. The inlet flow passageway(s) extend between the one end and a sealed region of the adaptor, and are used to direct fluid from the manifold block to the filter. The adaptor includes auxiliary ports formed in the tool-receiving portion that communicate with the inlet flow passageways and permit monitoring thereof.

  • High pressure detachable/retractable stopper plug
    Patent number: 10914389
    Abstract: A system for stopping flow in a pipe with a plug positioned in the pipe to allow for repairs of the pipe. The plug comprises a body with an inflatable or compressible member, and a cap and connector valve on the body. An inflation line with a coupling connects to the valve for blocking off and sealing a damaged area of the pipe. An inflation line is used to deposit and retrieve the plug within the pipe before and after a repair is made.
