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.
