Patent ID: 8596689

Claim:
A coupling for connection to a fluid component having a first fluid passageway therethrough and an externally-threaded male end, the coupling comprising: a coupler having a second fluid passageway therethrough, the coupler having a socket end with an opening and a generally annular locking member received coaxially in the socket end opening; and a generally tubular plug having a third fluid passageway therethrough and extending in an axial direction between a first end insertable coaxially in the socket end opening of the coupler and a second end configured to receive the male end of the fluid component, the plug having a radial inner surface including an internally-threaded portion threadably engageable with the externally-threaded male end of the fluid component when received in the second end of the plug, and a radial outer surface including a profiled portion disposed in a radial direction opposing the internally-threaded portion and in the axial direction disposed coextensive with the internally-threaded portion, the plug comprising a generally tubular body extending between a first end opening and a second end opening forming the second end of the plug, and a generally tubular insert having a channel therethrough forming the third fluid passageway, the insert extending between a forward end disposed coaxially with the first end opening of the body and a rearward end extending into the body, wherein with the male end of the fluid component being threaded into the second end of the plug such that the first fluid passageway of the fluid component is joined in fluid communication with the third fluid passageway of the plug, as the first end of the plug is inserted coaxially into the socket end opening of the coupler, the locking member is received coaxially thereover and into an interfering engagement fit with the profiled portion of the plug outer surface locking the plug into the coupler with the second fluid passageway of the coupler being joined in fluid communication with the third fluid passageway of the plug, and wherein when the coupling is connected to the fluid component the male end of the fluid component has a generally annular inner sealing surface surrounding the first fluid passageway, and the insert rearward end has a generally annular outer sealing surface abuttingly engageable against the inner sealing surface of the fluid component male end forming a fluid tight seal therebetween when the fluid component male end is threadably engaged with the plug.
