Product Detail

Product Introduction of the custom rubber cap.

A custom rubber caps is a plug designed for insertion into the end of a pipe to stop the flow of water, wastewater, stormwater or sewage to allow work crews the opportunity to effect repairs to the pipeline.

custom rubber caps may be conical, to fit into pipes ranging in size from the smallest diameter of the cone-shaped plug to the plug's largest diameter. They may be round inflatable or use a mechanical system to hold them in place.

1.It is used for the protection of screw holes and bolts in electroplating, electrophoresis, powder spraying, painting, sandblasting, shot blasting, anodizing, plastic spraying and other surface treatments, and can also be used for anti-collision and dust protection of some workpieces with precision threads.

Compared with plastic sleeve, it has the advantages of variable size, wide application range and aging resistance. Compared with PVC plastic sleeve, it has significant advantages such as thicker wall thickness and more collision resistance.

2. Normal temperature resistance 260 °C - short-term temperature resistance 315 °C

3. acid and alkali resistance, corrosion resistance

4. can also be used in mechanical equipment transportation or precision workpiece in the workshop processing flow to protect the stud

4. Why is rubber used to produce industrial products?

Rubber has certain unique properties which makes it suitable to produce rubber products which are widely used in various industrial applications. Rubber is water repellent. It is resistant to alkalies and weak acids. Rubber has elasticity, toughness, impermeability, adhesiveness, and electrical resistance. These properties make rubber useful as an adhesive, a coating composition, a fiber, a molding compound, as well as an electrical insulator.


5. Which type of rubber is best for my application?

There are a range of natural and synthetic rubbers with different properties, making some more suitable than others for particular applications–the key of course is choosing the most appropriate one! For specific requirements, please ask our rubber products specialists for guidance.
