ABSTRACT:
A union coupler assembly for coolant lines comprising a coupler body, a first coolant line end portion, and a second coolant line end portion. The coupler body has a passageway extending between first and second ends, two tapered annular grooves, a snap ring disposed within each tapered annular groove, and a plurality of o-rings seated in corresponding annular grooves. The coolant line end portions are fabricated from metal and have tapered ends and grooves formed in their outer surfaces. The coolant line end portions are movable between an engaged position, wherein the snap rings engage the grooves in the coolant line end portions, and a disengaged position, wherein the snap rings do not engage the grooves in the coolant line end portions. When the coolant line end portions are in the engaged position, the tapered end of the first coolant line end portion abuts the tapered end of the second coolant line end portion to prevent inward movement of the coolant line end portions, and at least one o-ring seals each coolant line end portion with respect to the coupler body.
