Abstract: A seal fitting assembly comprises a first block having a first aperture, a second aperture, and a first annular sealing surface surrounding the first aperture. A second block has a third aperture and a fourth aperture. An insert has a fifth aperture, a second annular sealing surface, and a second threaded portion. A first seal structure is disposed between the first annular sealing surface and the second annular sealing surface. An adapter has a sixth aperture, a surface of the adapter defining the sixth aperture including a third threaded portion configured to engage the second threaded portion of the insert. A second seal structure is disposed between the insert and the adapter. A fastener is received in the second aperture of the first block and the fourth aperture of the second block.

Abstract: A flow control device for conveying a fluid therethrough includes a port having an engaging end configured for engagement with a tube fitting and an inner surface defining a passageway configured to provide fluid communication through the flow control device. A shoulder is formed on the inner surface of the port adjacent the engaging end. The shoulder defines a first seating surface and a second seating surface. A protuberance is formed on one of the first seating surface and the second seating surface.

Abstract: A charge valve assembly for an air conditioning system includes a valve housing having a first end, a second end, and an inner surface defining a cavity. A valve core assembly is received in the cavity of the valve housing through the second end of the valve housing. The valve core assembly has a first end, a second end, a flow channel extending from the first end of the valve core assembly to the second end of the valve core assembly, an inner sealing surface, and a pin slideably received in the flow channel between an open position and a closed position. The pin has a primary seal selectively engaging the inner sealing surface of the valve core assembly and closing the flow channel at the second end of the valve core assembly when in the closed position. The pin biases towards the first end of the valve housing.

Abstract: A seal assembly for an HVAC system includes a first block having a first aperture and a first sealing surface, a second block having a second aperture and a second sealing, and a conduit having a tube portion with an axially extending aperture and a flange extending radially outwardly from an end of the tube portion. The tube portion is disposed within the first aperture of the first block and the flange is disposed between the first sealing surface of the first block and the second sealing surface of the second block and is configured to deform when compressed therebetween. The seal assembly further includes an insert providing fluid communication between the aperture of the tube portion and the second aperture of the second block. A first end of the insert is received in the aperture of the tube portion of the conduit.
