SUPERLOK ½" X ½ TUBE UNION

SUPERLOK ½" X ½ TUBE UNION ALSO KNOWN AS PLUMBING UNIONS ARE AN ESSENTIAL TOOL FOR ANYONE DEALING WITH HYDRAULIC SYSTEMS AND PIPES. THEY DO EXACTLY WHAT THE NAME IMPLIES - THEY JOIN TWO PIECES OF METAL TUBING TOGETHER IN A SECURE LEAK-PROOF CONNECTION. IN TIMES PAST THESE UNIONS WERE SOLDERED OR EVEN BRAZED TOGETHER; BUT MODERN TUBE UNIONS MAKE THE JOB MUCH EASIER AND QUICKER. MOST TUBE UNIONS ARE MADE OF EITHER COPPER STEEL OR BRASS AND CAN BE FOUND IN A VARIETY OF SIZES. THEY WORK BY HAVING TWO PIECES THAT THREAD TOGETHER TO FORM A TIGHT JOINT; THE UNION NUT IS THEN TIGHTENED AGAINST THE GASKET INSIDE THE UNION. THIS CREATES AN AIRTIGHT SEAL WHICH PREVENTS WATER OR OTHER LIQUIDS FROM LEAKING OUT OF THE SYSTEM.
