SURFACE FINISH FOR A PRESS-FIT PART

摘要

The subject invention relates to a press-fit connection for sealing a fluid pipe to a manifold assembly. The manifold includes a manifold body for transferring fluid and at least one generally cylindrical port having a proximal end in fluid communication with the manifold body and a distal end defined by a peripheral rim forming an openin g therein. The fluid pipe includes an elongated tubular body having a first end dimensioned to be received within the opening of the port and a longitudinally opposing second end. The port further includes an inner cylindrical surface defined by a plurality of parallel raised ribs spaced apart by a plurality of recessed grooves extending between the proxim al end and the distal end of the port. The press-fit connection includes the raised ribs deformed against the fluid pipe in response to the first end of the fluid pipe being received in the opening of the port and forced from the distal end toward the proximal end to create a flui d tight press-fit connection between the fluid pipe and the port.
