Powered by a reliable 21V motor, this cordless caulking gun delivers up pushing force, making it capable of handling high‑viscosity materials such as structural sealants, silicone with ease. It maintains consistent power output throughout the job, ensuring smooth, even dispensing without interruptions. Whether you’re working on home renovations or professional construction projects, this caulking gun provides the strength and reliability you need to get the job done efficiently.

Speed Adjustable Control

Equipped with 4 adjustable speed settings and a stepless variable speed trigger, this cordless caulking gun provides precise control over glue flow for a wide range of applications. Lower speeds are perfect for detailed work that requires steady, accurate application, while higher speeds easily handle heavy‑duty tasks such as window installation, tile grouting, or large‑area sealing. The variable trigger allows you to fine‑tune the flow in real time, giving you full command over the amount of material dispensed. This level of control ensures clean, professional results with minimal waste and maximum efficiency

Universal Cartridge Compatibility

Designed with a universal bracket, this caulking gun fits most standard cartridges, including single‑component and two‑component adhesives in various ratios, making it highly versatile for different projects. The tool‑free adjustment mechanism allows you to switch between different cartridge sizes quickly and easily, without the need for extra tools, saving valuable time on the job. The sturdy clamping system holds cartridges securely in place, preventing movement or shifting during dispensing and ensuring a steady, consistent flow for precise and professional results every time.

Auto-Retract Function

Featuring an intelligent anti‑drip system, the cordless caulking gun automatically retracts the push rod slightly when the trigger is released, stopping the glue flow instantly to prevent messy drips and excess waste. This function is particularly useful for vertical or overhead applications where dripping can ruin surfaces. The dual‑seal piston and check valve further enhance leakproof performance, ensuring no glue seeps out during use or storage, keeping your workspace clean and professional.

MVM 21V Battery Ecosystem Compatibility

As part of MVM’s unified 21V cordless tool platform, this caulking gun shares batteries and chargers with other MVM tools such as trimmers, saws, and blowers, eliminating the need for multiple power sources. The quick‑release battery slot ensures a secure and stable connection, providing consistent power even during extended use. This compatibility not only saves you money but also makes it easy to keep all your tools powered up and ready to go.

Ergonomic Design with Vibration Reduction

Featuring an ergonomic soft‑grip handle wrapped in anti‑slip rubber, this caulking gun fits comfortably in your hand and reduces fatigue during long work sessions. The handle is contoured to match natural hand movements, allowing you to maintain a secure grip even when your hands are slightly sweaty or covered in dust. The internal vibration‑dampening system minimizes motor‑generated vibrations, providing a smoother and more comfortable operation that helps reduce strain on your wrist and forearm. With balanced weight distribution, it’s easy to maneuver in tight spaces, around corners, and in overhead positions
