“I am a GPN 608.”

It has a universal application and can be removed at lightning speed.

Our latest GPN 608 – a tapered closure with removal tab – can be used as a versatile cap or plug. It not only seals holes and internal threads in a reliable way, but is also ideal for protecting bolts and external threads. Thanks to its conical shape, it can bridge any tolerances without problems. It is made of PE-LD – a durable and malleable material that provides for a great fit and an excellent clamping behaviour. Its special feature, however, is the ergonomically shaped, lateral removal tab in the patented tab design. Because this not only ensures that the GPN can be removed quickly and easily: its flat-lying side tab utilises even minimal space in an optimal way so that no installation space whatsoever is wasted. Depending on the application, we can even manufacture the tapered closure according to VDA Volume 19 and ISO 16232 in our cleanroom, which was specifically set up for this purpose.


At least as quick: our new next day delivery service.

From now on, Christina and her colleagues shall be in charge of our new next day delivery service ensuring an even faster delivery of stocked items in the extensive standard program: if your order is placed by 4.30 pm on business days (Friday until 2 pm), you will receive your products by noon on the next business day at the latest. Of course, we will prepare everything according to your needs. Since we do not use standard packaging, you can choose the exact amount of products you need in each order. Please note that our new service includes one item position per order and only applies to national deliveries within Germany.


You can find our entire standard and special range of products in the KAPSTO® catalogue. Should you have any questions about a particular protection cap or plug or a specific application, feel free to call us on +49 (0)4442 982 9100.
