The Real Cost Of Low Push Force

When the sealant gets tough,
ordinary guns struggle.

High-viscosity sealants demand more force, increase operator effort, and make consistent dispensing harder to maintain.

High material resistance
Thick or cold sealants require greater pushing force.

Operator fatigue
Repeated manual dispensing increases hand strain over long applications.

Inconsistent application
Changing material resistance can make a clean, even bead harder to maintain.

Fatigue
More hand force. More strain over long applications.

Rework
Uneven bead flow means more correction and cleanup.

Downtime
When the gun cannot push the material, the job stops.

Performance Functions

Built to control
every push.

High-Thrust Drive System
Designed to maintain strong pushing force under high material resistance.

6-Speed Electronic Control
Six selectable output levels for controlled dispensing speed.

Auto-Retract Pressure Release
The plunger retracts automatically when the trigger is released.

Continuous Dispensing Mode
Lock function supports continuous extrusion for long applications.

One pull.
One clean bead.

Load the cartridge, dial in the speed, and get a smooth, controlled bead with less effort. The DCG-101 combines 6-speed control, cordless freedom, and built-in LED visibility to keep sealing work fast, clean, and consistent.

More pushing force, better flow control, and a compact design for demanding sealing work.

    FAQ

    Common Questions.

    How much pushing force does the DCG-101 deliver?
    Maximum pushing force is 6,500 N, which is intended for thick sealants and adhesives that are hard to dispense with lower-thrust tools.

    How does 6,500 N compare with other cordless caulking guns?
    Compared with selected professional 300-310 ml cordless caulking guns that publish between 3,000 N and 5,000 N, 6,500 N is 30.0% to 116.7% higher published thrust. Comparison is based on published manufacturer figures for selected models, not on side-by-side testing.

    What cartridge size does it take?
    The DCG-101 uses a 300 ml cartridge holder.

    What does the constant speed control do?
    An electronic dial sets the dispensing speed from 0 to 8.5 mm/s, so the bead stays consistent instead of depending on how hard the trigger is squeezed.

    What is anti-drip auto-retract?
    When the trigger is released the plunger retracts to relieve pressure in the cartridge, which helps stop material continuing to flow after the bead is finished.

    How heavy is the tool?
    Net weight is 1.60 kg without battery and 2.30 kg with battery, in a 420 mm body.

    What battery does it use?
    The DCG-101 runs on the M7 18V Li-ion battery platform, shared with other M7 cordless tools.

    What kind of work is it for?
    Construction sealing, window and door installation, automotive bonding, renovation, and other jobs involving repeated or high-viscosity material application.

    Is the DCG-101 the same as a battery caulking gun or an electric caulking gun?
    Yes. Cordless caulking gun, battery caulking gun and electric caulking gun all describe the same type of tool. The DCG-101 is a cordless sealant gun powered by an 18V Li-ion battery, and it is also used as a cordless silicone gun or cordless mastic gun depending on the material being dispensed.

    Is an electric caulking gun worth it compared with a manual one?
    A manual gun depends entirely on hand force, which limits how consistent a long bead can be and how much high-viscosity material can be dispensed before fatigue sets in. An electric caulking gun drives the plunger with a motor at a set speed, so output does not change with grip strength.

    Does it come with a battery and charger?
    The DCG-101 runs on the M7 18V Li-ion platform. Battery and charger packages vary by market — tell us your market in the quote form and we will confirm the cordless caulking gun with battery and charger options available to you.

    Does it take 600 ml sausage packs?
    No. The DCG-101 uses a 300 ml cartridge holder. If your application needs a sausage caulking gun for 600 ml foil packs, contact us and we will advise on the right tool for that format.

    How do you use a cordless caulking gun?
    Load the cartridge into the holder, cut and fit the nozzle, set the speed level, then pull the trigger and move the gun along the joint at a steady pace. Release the trigger at the end of the run and the plunger retracts to relieve pressure in the cartridge.

    Are you a caulking gun manufacturer or a trading company?
