• Material: Stainless steel

How to Use It

Use it on the initial make-up of a DK-Lok two-ferrule tube fitting. Per DK-Lok's instructions:

• If the gauge does not fit into the gap between the nut and the body hex, the fitting is tightened enough.
• If the gauge fits into the gap, the fitting needs more tightening.

Don't use the gauge on a remade fitting. When you remake one, tighten back to your mark and go slightly past it.

Other Sizes

For 5/16" tube, use the DIG-5-S. For 1" and 25 mm tube, use the DIG-16-S. To check that the tube is bottomed in the fitting, pair the gauge with a DK-Lok DTM tube depth marking tool. See the rest of our tube installation tools.
