Protective Plugs and Protective Caps

Plastic protective plugs and caps are used to seal and secure sensitive and critical connecting parts and end pieces. Metal components are usually galvanized or painted to protect against corrosion. By attaching protective caps, these components are protected from scratches or other damage.

Protective plugs are used to cover openings and bores or as dust protection for sensitive components. Both products can be manufactured in various plastics as well as in different colors. Due to their simple but at the same time indispensable function, they are used in the entire machine and plant construction as well as in the hydraulic industry.
