Sealey AK4803 Heavy Duty Mastic, Sealant and Caulking Gun

The Sealey AK4803 is a heavy-duty skeleton-frame caulking gun designed for professional application of mastic, sealant and caulking compounds. This robust tool accommodates standard 310ml and 380ml cartridges up to 280mm in length, making it suitable for a wide range of sealing and bonding tasks across construction, maintenance and repair applications.

Built with convenience in mind, this caulking gun features an integrated tip cutter that eliminates the need for separate cutting tools – simply insert the cartridge nozzle and squeeze the handle to cut it to size. The built-in tip piercer and cleaner is ideal for clearing dried sealant from nozzles, helping to extend cartridge life and reduce material waste. A hook end allows the gun to be attached to your belt for easy access when working at height or moving between tasks.

The skeleton-frame design provides a lightweight yet durable construction, with the tool weighing just 0.77kg despite its 435mm overall length. This makes it comfortable to use throughout extended applications whilst maintaining the strength required for consistent dispensing of thicker sealants and mastics commonly used by builders, decorators and general contractors.

• Integrated tip cutter and piercer eliminates the need for additional tools
• Compatible with both 310ml and 380ml standard cartridge sizes
• Belt hook for convenient carrying and quick access on site
