Abstract: An improved method of applying an epoxy paint coating to a tube includes the step of mixing plastic particles into the epoxy paint prior to application on the tube. The plastic particles improve the paint's abrasion and corrosion resistance and also improves the paint's ability to withstand downstream forming operations.

Abstract: A tube having a cylindrical main body and a thin wall defined by an inner surface and outer surface. The tube includes a first segment having a generally constant cylindrical cross-section and another segment having a variable cross-section containing convolutions to allow for flexing of the tube during installation. The convolutions extend less than the entire circumference of the tube or have tapered side walls which substantially reduce the size of the convolutions as the convolutions extend from one position along the circumference to a second position.

Abstract: A quick connector for fast connection of fluid carrying assemblies such as a mating tube and a fluid unit includes a connector body that houses the connector components and accepts a redundant clip, which is adapted to engage an upset bead of the male tube. The redundant clip is generally L-shaped and includes a retaining head that is inserted into the connector body and is adapted to engage the upset bead. A body portion, which extends along the side of the connector body and in the preferred embodiment is contoured to mate with the connector body, extends between the retaining head and a base member. The base includes a camming edge for facilitating the insertion of the retainer head into the connector body.

Abstract: A quick connect connector is disclosed. The connector includes a connector housing having a first and a second ends. A first chamber is provided in the housing between the first and the second ends for receiving a sealing member therein. A retaining collar is slidably mounted on the housing between the first and second ends of the housing and includes at least one radially deflectable locking portion thereon. The radially deflectable retaining portion is adapted to engagingly contact a flange portion of a tubing member inserted in the housing to retain the tubing member in a locked position relative to and sealingly engaging the sealing member between the retaining portion and the first end of the housing. The locking portion is received within a groove of the housing to lock the collar to the housing and secure the connection. The tubing connector is resiliently urged out from the housing and against the engaged retaining portion of the housing.
