Frequently Asked Questions (FAQ)

Where can insulating hoses be used?

GREMCO’S insulating hoses are used in a wide variety of environments. The PTFE liner, for example, is installed as a mechanical actuating cable in automobiles. GREMCO’s insulating hoses are nevertheless also commonly found in other industries. In this respect, PUR/PVC hoses are installed in mechanical roller blinds to insulate against noise and to maintain the necessary distance, while so-called FEP spirals are commonly used for “water purification”.

If you would like to know the ideal application of a GREMCO insulating hose product for your company, please contact our trained technical specialists. We will show you potential areas of use and develop the ideal solution for you.

Which material is relevant for my insulating hose?

Insulating hoses differ depending on the raw material or on the combination used and, for this reason, constitute a very wide product field. Silicone insulating hoses, for example, can provide high elasticity with simultaneous heat resistance, while PTFE insulating hoses are used more for their high resistance to abrasion and aggressive chemicals.

At GREMCO, our PVC insulating hoses are available in a variety of colors and, therefore, can be successfully used for labeling. Countless other materials and combinations are also included in our GREMCO product portfolio. If you have any further questions, please contact our straight-forward customer service engineers. We are here for you.

How do I know which insulating tube I need?

The right choice of insulating hose is crucial for a result-oriented use of the product. It can be difficult to keep track of the relevant criteria, as we already have a four-figure repertoire of products in the area of insulating hoses. As a rule, the most important criteria to consider are length, wall thickness, material, required approvals and color of your cable protection product. Make sure these characteristics are fully clarified.
If you are still unsure, please contact our trained professionals. From the choice of material to the final decision-making process, we will support you at no extra cost in order to guarantee you the optimal product solution. That way, you will avoid costly incorrect purchases and experience the smooth employment of your customized insulating hose product.

What do I need an insulating hose for?

Depending on the application, an insulating sleeve can be used for cable bundling, as cable protection and as electrical and thermal insulation for cables and wires. At the same time, the material composition varies from application to application (for example, PVC, PTFE, FEP, silicone and many other raw materials). At GREMCO, we can also manufacture explicit materials to withstand high mechanical loads or extreme temperatures.
