End Caps

What are End Caps?

End Caps, often overlooked but critical in engineering projects, serve as protective or decorative coverings at the extremities of objects such as screw threads, tubes, rods or pipes. These seemingly simple components play an invaluable role in preventing wear, tear and corrosion while enhancing safety by covering sharp edges. With various types like push-on, quick fit, and sealing plastic end caps, Accu’s range caters to an array of applications from simple assembly requirements to complex engineering tasks.

How End Caps Work.

The core function of plastic caps lies in their ability to attach securely to the ends of various objects. They achieve this via a friction fit, threaded mechanism or flanges that create contact with the threads or tube. The choice depends on the specific application, with push-on being the most basic, quick fit offering ease of installation, and sealing end caps providing an extra layer of protection against leakage or contamination.

What Material End Caps Are Made From.

We predominantly manufacture our caps from low-density polyethylene in line with the ethos of robust engineering. This material boasts excellent durability, flexibility, and chemical resistance, making it suitable for a plethora of applications. Whether you're in need of a flexible end cap or rubber end caps, rest assured that the material quality adheres to the highest industry standards.

What Size and Type End Caps Are Available.

At Accu, we understand the nuances of engineering projects. Our cap ends range in thread sizes from M8 (8mm) for detailed work, up to M62 (62mm) for large bore applications. Available in colours red, yellow, and white, we offer options that suit both functional and aesthetic requirements. If you are looking for tube end caps, scaffold end caps, or cap ends for any other specific application, we've got you covered.


Q: What are rubber end caps used for?.

A: Rubber end caps are particularly useful in applications requiring higher flexibility and better impact resistance, such as shock absorption in machinery.

Q: How do you measure end caps?.

A: Measurements for plastic caps are typically based on the external diameter of the object they will fit onto, usually specified in metric units such as millimetres. This external diameter of the component needs to match up to the internal diameter of the plastic cap ends.

Q: Do pipe ends have to be capped for storage?.

A: Absolutely, capping pipe ends with a PVC end cap is crucial for storage as caps are designed to prevent ingress of dust, moisture, or other contaminants that may affect the material integrity.

Q: What is the difference between a plug and an end cap?.

A: While both serve similar purposes, plugs fit inside the object they are protecting, whereas end caps for tubes fit over the outside.

Q: Are plastic stop ends permanent?.

A: Plastic end caps can be either temporary or permanent, depending on the application's requirements. They are generally easier to remove compared to metal alternatives, making them a versatile choice.
