DTM-10-C

DTM-10-C is a DK-Lok DTM tube depth marking tool for 5/8" OD tubing. 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.

• Tube OD: 5/8"
• Fits: DK-Lok two-ferrule tube fittings

How to Use It

Per DK-Lok's operating instructions:

1. Insert the tube into the DTM until it bottoms on the tool.
2. Mark the tube with a pen at the top of the DTM.
3. Remove the tube from the DTM and insert it into the DK-Lok fitting until it bottoms on the shoulder of the fitting body.
4. If you can still see the mark above the fitting nut, the tube isn't fully bottomed. Push it in until the mark disappears before you make up the fitting.

Pair It With a Gap Gauge

After make-up, check the fitting with a DK-Lok no-go gap inspection gauge. The DIG-468 covers 1/4", 3/8", 1/2" and 3/4" plus 6, 10, 12 and 18 mm in one gauge. See the rest of our tube installation tools.
