ABSTRACT:
A quick disconnect forming a coupler for high pressure fluid lines that has a first hollow member attached to a second hollow member in fluid-tight relationship with an attachment collar having relatively coarse threads thereon for quick attachment and detachment of the first and second members. A cylindrical stop ring is threadedly attached to one of the members to form a second shoulder in spaced opposition to a first shoulder on one of the members such that the attachment collar can move axially only between the two shoulders. A resilient O-ring is formed in a recess on the second member and engages an annular recess on the attachment collar to resist movement of the attachment collar by vibration.
