New GPN 212 end cap provides optimum protection for fuel pipes.

The new pipe end caps, which have been specifically developed for pipes with a diameter of 6 and 8 mm, are now available for immediate delivery.

When customers approach us with specific requirements for plastic protective caps or plugs, at Pöppelmann KAPSTO® we do our best to provide them with a solution. The GPN 212 pipe end caps are a recent example of our successful development work. Following a customer request, KAPSTO® application engineers have developed this new standard series specifically for 6 and 8 mm fuel pipes. The cap protects the pipes from contamination during transport and shields the coating of the ball bushing at the end of the pipe. Since the flanging is not standardised, the GPN 212 must also be able to overcome different spherical geometries. Thanks to the highly flexible plastic (TPE), the cap adapts to the individual contour of each ball bushing perfectly.


The advantages of the new GPN 212 at a glance:

  • Time-saving thanks to easier handling. The ergonomic grip flap enables easy and quick assembly and disassembly. Its shortened design also saves storage space.
  • Can be used even at high temperatures. Since it is made of thermoplastic polyester elastomer (TPE), it can withstand temperatures up to 150 °C.
  • Extremely multi fuctional in use. The flexible TPE material is predestined for overcoming different counterpart geometries with outside diameters ranging from 8 to 11.2 mm. The pipe end cap is also particularly suitable for the protection of pipes with ball bushings – for instance, it protects against dust during transport and protects the protective coating of the flanging at the tip of the pipe.
  • Individual amounts always available from stock. As part of our standard range with over 3,000 versions, the GPN 212 is always available for immediate delivery. Since we do not have standard packaging, you are free to choose the amount you need with every order.
  • Free samples. We would be pleased to send you free samples without obligation. To request a sample, please fill in our special sample form.


Fast, targeted and safe: custom-made protective caps and plugs by Pöppelmann KAPSTO®.

Pöppelmann KAPSTO® is the right development partner, even when it comes to individual custom-made products. Thanks to more than 50 years of experience and a concept of in-house master moulds, the family business from Lohne is able to develop and produce them cost-effectively. Usually there is no need to build new moulds from scratch – in most cases it is sufficient to produce special mould inserts for readily available moulds. Moreover, we also take over all those numerous little jobs which a project involves: from support to development (including Rapid Prototyping) right through to mould-making and efficient serial production. This allows our customers not only to save a lot of time but also additional costly interfaces - such as external development agents and mould constructors.
