Protective Plugs & Caps

Plastics - protection solutions for all areas of application

Caps for the outer cover and plugs for the inner seal offer optimum protection during storage, transportation, assembly or processing of your goods by sealing inner diameters and covering outer diameters.

They protect your sensitive components from dirt ingress, contamination or damage and are widely used in almost all branches of industry.

We offer short-term availability of a wide range of variants from a broad standard program.

Most of our plastic protection solutions are made from recycled materials, thus conserving naturally occurring resources.

Application areas

Due to the countless possible applications, protective caps and plugs must have a wide variety of geometries. Non-threaded versions are ideal for protecting protruding components (screw heads or nuts), as they are relatively easy to fit and can be removed again if necessary. Non-threaded plugs can be used permanently in drill holes or other openings, but are difficult to remove. Screw plugs or sealing screws are ideal here. These are screwed or unscrewed directly into the intended opening, making them easy to remove. Another option is to use so-called tab plugs, which are attached for quick installation by simply pressing them into place, but are just as easy to remove again thanks to the existing tab.

Warehousing

To simplify your stock-keeping, it is advisable to check whether protective plugs can also be used as protective caps for corresponding dimensions. The protective plugs with ring opener type TL-5-000 are particularly suitable for covering threaded openings when spraying paint due to their sealing edge.

Our service & products

Different variants and customizations possible

Both protective plugs and protective caps can be manufactured in various plastics and colors and are used throughout the mechanical and plant engineering and hydraulic industries due to their simple yet indispensable function. We comply with DIN 16901 for all functional dimensions. For your specific application, it is best to request a sample for testing.
