DPS-8-C-C

DPS-8-C-C is a DK-Lok DPS manual pre-swaging tool for 1/2" OD 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: 1/2"
• 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.
