The Silicone Gun 400ml (Turquoise) is a hand-operated caulking gun designed to dispense 400 ml sealant cartridges and compatible sausage packs. Its primary use is controlled application of silicone, acrylic and polyurethane sealants and adhesives in sealing, glazing and jointing tasks where a consistent bead and reliable feed are required.

Constructed with a pressed mild steel frame finished in a durable turquoise polyester powder coat, the gun resists chipping and surface corrosion encountered on site. The thrust rod is hardened steel with zinc passivation for wear resistance and reduced corrosion of the drive components. This is an open-frame, single-handed tool with a ratchet-style manual drive and quick-release lever, giving positive control over flow and an easy stop to prevent excess squeeze. As a cartridge-style gun it does not use a threaded nozzle connection; instead it accepts industry-standard 400 ml cartridges and compatible sausage packs that conform to common ISO/DIN cartridge dimensions.

Typical applications include window and door glazing, sanitary sealant work in bathrooms and kitchens, external jointing for cladding and rainproofing, and general bonding tasks in building maintenance and fit-out. Trades and industries that commonly use this tool are joinery, glazing contractors, general builders, plumbing and HVAC installers, and facilities maintenance teams. It is also suitable for DIY and workshop environments where professional sealant application is needed.

Key benefits include long service life from the hardened thrust rod and a corrosion-resistant finish that suits indoor and outdoor use. The ratchet drive provides dependable force for viscous materials and the quick-release minimises material waste and drips at the end of a run. Compatibility with standard 400 ml cartridges makes this gun a straightforward replacement or addition to existing toolkits, and the ergonomic handle with a soft-grip profile reduces hand fatigue during prolonged use.
