It shows you exactly how deep the tube has to go into a DK-Lok fitting, so you can confirm the tube is bottomed before you tighten the nut. A tube that isn't bottomed is a common cause of fitting leaks. A-Best Industrial Inc. Fittings, Valves, and Tubing is an authorized DK-Lok distributor in San Pedro, CA, and can quote price and lead time, usually the same day.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e DK-Lok two-ferrule tube fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow to Use It\u003c\/h2\u003e\u003cp\u003ePer DK-Lok's operating instructions:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eInsert the tube into the DTM until it bottoms on the tool.\u003c\/li\u003e\n\u003cli\u003eMark the tube with a pen at the top of the DTM.\u003c\/li\u003e\n\u003cli\u003eRemove the tube from the DTM and insert it into the DK-Lok fitting until it bottoms on the shoulder of the fitting body.\u003c\/li\u003e\n\u003cli\u003eIf you can still see the mark above the fitting nut, the tube isn't fully bottomed.
