DPS-20M-C-C

DPS-20M-C-C is a DK-Lok DPS manual pre-swaging tool for 20 mm tubing. It sets the nut and ferrules on the tube before the tube goes into the fitting, which makes installation easier in tight spots, on panels and where you can't get a wrench on the fitting body. 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.

• Type: Manual pre-swaging tool (no power or hydraulics needed)
• Tube OD: 20 mm
• Material: Carbon steel
• Fits: DK-Lok two-ferrule tube fittings

How to Use It

Per DK-Lok's operating instructions:

1. Clamp the DPS steady in a vise.
2. Put the DK-Lok nut and ferrules on the tube.
3. Push the tube end into the DPS until it bottoms on the tool's shoulder, then finger-tighten the nut.
4. Mark the nut at the 6 o'clock position.
5. Wrench-tighten the nut 1-1/4 turns, to the 9 o'clock position.
6. Back the nut off and pull the tube with its pre-swaged ferrules out of the tool. If it sticks, rock the tube gently back and forth. Don't rotate it.

Final Make-Up in the Fitting

Insert the pre-swaged tube into the fitting body until the front ferrule seats and hand-tighten the nut. Wrench-tighten to the pulled-up position, where you'll feel a sharp rise in torque, then tighten slightly more.

Which Pre-Swager Do You Need?

The DPS covers 1/4" through 3/4" and 3 through 20 mm. For larger tube, use the DHS-2A manual hydraulic swaging unit or the DES-1A electric swaging unit. DK-Lok requires a pre-swaging unit to install 1-1/4", 1-1/2" and 2" fittings and 28, 30, 32 and 38 mm fittings. See our pre-swaging tool comparison and the rest of our tube installation tools.
