Description

“LEEK PRUF”® FUSIBLE PLUGS

1.  The “Leek Pruf”® plug has a male flare to connect to a female flare on the receiver or accumulator. A soft copper gasket which comes attached and oiled is used and pipe compound is eliminated. The result is a permanent leak tight connection.
2. Alloy in the “Leek Pruf”® plug is located so that it is not disturbed or under stress when the plug is tightened since the section of the plug containing alloy is not contained within the threaded section. Since “Leek Pruf”® plugs by Refrigeration Research use an eutectic alloy (melts sharply at one temperature) and the alloy is not distorted, the relief temperature is positive.

LEEK PRUF® PLUGS ARE EXCLUSIVE ON RECEIVERS AND ACCUMULATORS BY REFRIGERATION RESEARCH.

APPROVED AND USED BY LEADING CONDENSING UNIT AND SYSTEM MANUFACTURERS.
