This 310 ml caulking gun is a hand-held applicator designed for dispensing sealants, adhesives and mastics supplied in standard 310 ml cartridges. It is intended for general workshop and on-site use where controlled, continuous extrusion is required, such as sealing joints, bonding panels and filling gaps in construction, glazing, plumbing and vehicle body repair.

The gun features a mild steel frame manufactured to EN 10025 S235 grade and a hardened push rod finished with a corrosion-resistant zinc electroplate to ISO 2081. The body is protected with an electrostatic powder coat to reduce surface corrosion in typical building and trade environments. A forged-steel ratchet and pawl provide the drive mechanism; the tool incorporates a quick-release lever and anti-drip pressure-release function to halt material flow when the trigger is released. The pistol-grip head and moulded handle give a secure, ergonomically comfortable hold for repetitive use. The unit is compatible with standard 310 ml cartridges and most foil sausage packs of equivalent dimensions commonly used across UK and European trades.

Typical applications include external and internal joint sealing with silicones, polyurethanes and hybrid polymer adhesives, glazing bead application, sanitary sealant installation, and adhesive bonding in joinery and shopfitting. Trades and industries that commonly use this tool include builders, glaziers, plumbers, HVAC engineers, vehicle repair workshops and general maintenance teams. It is also suitable for DIY and light industrial settings where reliable bead control is required.

Key benefits of this caulking gun include corrosion resistance from the zinc-plated rod and powder-coated frame, robust construction for consistent extrusion force and a quick-release anti-drip mechanism to reduce waste. The steel drive components deliver the durability needed for frequent use while remaining compatible with standard 310 ml cartridge seals and nozzles used across ISO/DIN/BS markets.
