Duboschweitzer® bolt locking system

DUBO Ring provides an absolute protection against bolt loosening due to vibration.

You avoid the critical impact that may occur by bolted connections loosen over time.

DUBO Locking Ring and Isolator prevent the ingress of water and moisture between the bolt and flat items such as plates or flanges. By including a PA6-foil, the system also constitutes a barrier against galvanic reaction in structures with different metal alloys.

You will achieve a moisture-proof assembly that effectively protects against galvanic corrosion. The lifetime of the connection is extended.

DUBO components are produced in a strong and flexible polyamide, which is resistant to alkalis, inorganic neutral salt solutions, oil, grease, gasoline, alcohol, acetone, dilute acids and seawater.

The chemical resistance allows you to use just one, easy locking and protection system in almost all applications and environments.
