B&O SAN-100



The B&O model SAN-100 is a pneumatic sealant gun manufactured for the use of Semco and Techcon cartridges. Designed with a lightweight, retractable holder system, the SAN-100 does away with the standard steel tubed cartridge holders and can be used with or without the retainer.

This unique system (patent pending) requires only one cartridge holder to hold 2.5 oz, 5 oz, 6 oz, 8 oz and 12 oz cartridges. It is engineered for smooth dispensing, and the holder is designed to provide a full view of the cartridge, allowing the user to see the level of fluid inside the dispenser at all times.

This high end pneumatic sealant gun is made of polyamide 6 (PA6) with 30% fibreglass and from durable aluminium alloy. It comes without pressure control.
