Abstract: A quick connect fluid coupling, and more particularly a quick connect fluid coupling having a minimum number of parts, which can be quickly assembled and disassembled, and which provides a good seal in an environment which is subject to vibrations and to relative motion between a fluid line and a port defining structure.

Abstract: A fluid coupling for connecting a fluid line to a threaded port. The coupling includes a male member having a free end, a shoulder portion, and a tapered portion between the free end and the shoulder portion. The female member is provided with an enlarged portion, a groove in a reduced diameter portion which is disposed on the male coupling side of the female coupling, and a threaded end portion on the other side. The female member also has a bore having an enlarged portion and a reduced diameter portion, the reduced diameter portion in turn receiving an O-ring. Slots are provided in the female member between the spring clip groove and the enlarged portion for the reception of a spring clip.

Abstract: A fluid coupling assembly which is capable of interconnecting an oil cooler 26 disposed within a radiator header with an oil line 200 or 300 terminating outside of said header. The coupling includes a tubular fitting 204 or 304 which has a first portion brazed about a port 32 in the oil cooler and a second portion which is adapted to be secured to a header wall 37 or 70. The tubular fitting is provided with a bore and the tubular connector end portion 202 or 302 of the oil line is adapted to be telescoped within the bore to an assembled position. A seal 206 or 306 is mounted within the bore. Coupler means 208 or 308 are provided for holding the tubular fitting and the tubular connector end portion in their assembled position, the coupler means including a radially outwardly extending surface 246 or 346 on the tubular connector end portion and a spring wire clip 248 or 348 received within a groove 242 or 342 on the tubular fitting.

Abstract: A fluid coupling assembly 100 which is capable of interconnecting an oil cooler 26 disposed within a radiator header 12 with an oil line 130 terminating outside of said header. The coupling assembly includes a female fitting 106 which is capable of being brazed about a port in an oil cooler, the female fitting being provided with a threaded aperture which receives the externally threaded end of a male fitting 104. The male fitting is provided with an outwardly extending portion which is adapted to bear against one surface of a header wall, the female fitting 106 bearing, through a compressible washer 108, against the other surface of the wall 54. The male fitting is further provided with a circumferential groove in a cylindrical end portion which is capable of having a quick coupler 102 connected thereto. The quick coupler can be initially screwed onto the threaded end of an oil line 130.
