Heavy-Duty Sealant Gun for Precise Silicone & Adhesive Application
The ARC Pro-Seal Plus Sealant Gun is a professional-quality applicator designed for smooth and controlled dispensing of silicone, adhesives and sealants. Built with a durable metal construction and high thrust force, it provides reliable performance for demanding trade applications.
The gun features a high-strength aluminium casting handle and an 8mm powder metallurgy drive plate, delivering powerful and consistent pressure while reducing the risk of breakage. Its ergonomic low-fatigue handle design ensures comfortable use during longer jobs, while the rotating barrel allows easy access to tight corners and awkward angles.
A built-in unblock pin helps clear cartridge nozzles quickly on site, and the large U-shaped ladder hook allows convenient storage when working at height. Designed for professional performance, the Pro-Seal Plus offers precision and durability for everyday sealing and bonding tasks

TJ’s Tip
For smoother sealant application, cut the cartridge nozzle at a slight angle and start with a small opening. You can always widen it later if more sealant flow is needed, giving you better control and a cleaner finish.
