Abstract: An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a header at a cold end, and a plurality of core tubes. Each of the core tubes may have a first end and a second end. The ATAAC may further comprise a plurality of grommets each connecting the second end of one of the core tubes to a slot of the header. Each of the grommets may include an inner surface contacting the core tube and an outer surface contacting the slot of the header. The inner surface of the grommet may include radially-inwardly projecting regions contacting the core tube, and depressed regions providing clearance between the grommet and the core tube.

Abstract: An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a first header. The first header may include a plurality of slots each having a recessed groove. The ATAAC may further comprise a plurality of core tubes each including a first end inserted in a respective one of the slots of the first header. The ATAAC may further comprise a plurality of mechanical joints each connecting the first end of one of the core tubes to the first header. Each of the mechanical joints may include a C-ring inserted in the recessed groove of one of the slots, and a clamp clamping the core tube to the first header. The C-ring and the clamp may both be formed from a metallic material.

Abstract: A sealing member for a machine may include an elastomeric body configured to fit at least partially into a recess defined in at least one of two sealing surfaces of two mating parts of the machine. The elastomeric body may include a visible indicator portion extending out from between the two mating parts. The elastomeric body may further include an elastomeric compound, and at least one of a thermochromic dye and a piezochromic dye mixed into the elastomeric compound, wherein the thermochromic dye is adapted to change color upon exposure of the elastomeric body to a temperature above a threshold temperature, and the piezochromic dye is adapted to change color upon exposure of the elastomeric body to a pressure above a threshold pressure.
