Cartridge Silicone Caulk Gun EPM E-400-4500, capacity 300 ml

Cartridge Silicone Caulk Gun EPM E-400-4500, capacity 300 ml is a manual dispensing tool designed to apply silicone and similar sealant pastes from standard 300 ml cartridges. The gun gives controlled extrusion of sealants and adhesives for sealing, jointing and bonding operations in construction and general DIY. The device is intended for tasks that require an accurate, continuous bead such as glazing, sanitary sealing and window or door installation.

Advantages

The caulk gun features a manual push mechanism that allows precise control over flow rate and bead thickness, reducing material waste. Its construction is engineered to hold standard 300 ml cartridges securely, providing stable pressure during application. Ergonomic handle design reduces hand fatigue during extended use, while a reliable trigger and release system facilitates smooth start and stop of material flow. The tool is compatible with common silicone and sealant paste viscosities used in building and repair work.

Suitable for

• Applying silicone sealants around baths, sinks and sanitary fixtures
• Sealing window and door joints during installation or replacement
• General gap filling, jointing and weatherproofing in construction and repairs
• Bonding and adhesive dispensing where controlled bead application is required

Key specifications

• Cartridge capacity: designed for 300 ml cartridges
• Operation: manual push/trigger mechanism for controlled extrusion
• Compatibility: suitable for silicone and similar sealant pastes of standard viscosity
• Handle: ergonomic design to reduce user fatigue during prolonged use
• Control: trigger and release system for smooth start/stop of material flow

How to use

Prepare the surface by cleaning and drying the area to be sealed. Load a 300 ml cartridge into the gun according to the manufacturer's instructions for the cartridge, cut the cartridge nozzle to the required bead size and puncture the seal if necessary. Squeeze the trigger to start dispensing, maintaining a steady hand and consistent speed to lay an even bead of sealant. Release the trigger to stop flow and use the release mechanism to relieve pressure before changing cartridges or pausing work. Smooth the bead with a suitable tool or finger (with protective gloves) within the sealant's workable time.

Usage recommendations

Use cartridges compatible with 300 ml manual guns and select nozzle size based on bead width. Work in well-ventilated areas and follow the sealant manufacturer's instructions for curing times and surface preparation. Clean the gun after use to prevent cured material buildup and store the tool in a dry place.
