Abstract
A fluid coupling for a conduit which features a quick connect-disconnect construction between first and second coupling members. The first coupling member is connected to the conduit and is generally cylindrical, having a main portion and a reduced diameter portion. Peripheral grooves on the reduced portion contain sealing rings which form a fluid-tight seal with a second coupling member that fits over the first member, the sealing rings contacting an internal bore. The principal seal is provided by a resilient O-Ring which is located in the groove located at the intersection of a wall that intersects the reduced diameter portion of the first coupling member. This contacts a shoulder formed on a wall which intersects part of the bore of the second coupling member. This provides both axial and radial compression between the coupling members. The second peripheral groove is spaced from the first groove and contains another O-Ring as well as a fluoroelastomeric backup ring to enhance the seal. The two coupling members are interfitted and locked together by means of a U-shaped retaining pins that has legs inserted into opposing peripheral grooves on the main body portion of the first coupling member and the base of the second member.
