End Caps
Our selection of Plastic End Caps, Rubber End Caps, and Plastic Covers includes many different products. Each of these are suited towards all kinds of industrial and consumer employments. Manufactured from high-performance materials such as Nylon, Silicone, and HDPE, our End Caps are popular for may uses, including the covering of box sections, round tubing, and even metal posts.
Each End Cap comes in a number of industry standard sizes. Our caps are also geared towards uses such as finishing, masking, protecting, and sealing, hence the large number of options given. Also referred to as 'Covers', these are common-place within industries that deal with consumer goods. For example, within the automotive industry. This is where End Caps would be required to finish off any exposed screws, nut/bolt heads or manufacturing defects.

Frequently Asked Questions
Are these all the Caps you offer?
From standard, yes - however the name 'cap' is subjective meaning that we may well have an alternative solution for your use inside a different range, so we suggest checking with our sales team either via Live Chat or Phone on 01233 713 581.
Is it just Plastic and Rubber styles offered?
Mostly yes, however as previously mentioned we may well have an alternative product for your use. For example, our Metal Tube Inserts are often regarded as 'Caps for tubes' so we always suggest speaking to someone first.
Where do I start when measuring caps?
If you are unsure with how to measure, then please visit our fitting guide which should contain all required information aided by diagrams and examples.
Can I order custom plastic caps?
We are able to take orders for specialised plastic caps that are designed around the requirements of your project. From nylon blanking caps and pvc end caps, to LPDE tube caps, we have the material flexibility and technical experience to create caps that are tailored to different use cases. A custom plastic cap can be designed to specific dimensions to create a high quality bespoke solution. Use our contact form to get a price and lead time estimation for your next project.
Are post caps essential for extending the life of fence posts?
Yes, post caps are a simple but highly effective way to extend the life of timber and fence posts. By covering the exposed end grain, post caps help prevent rainwater from soaking into the wood, which can otherwise lead to rot, splitting, and mould. In the UK's wet climate, fitting post caps not only reduces long-term maintenance but also keeps fences looking smart for years. Our range includes durable plastic options to suit any garden or commercial fencing project.
How do pipe end caps protect pipes during transport and storage?
Pipe end caps act as protective barriers, sealing off the open ends of pipes to prevent dirt, dust, and moisture from entering. This protection is vital during transit and storage, as it maintains pipe cleanliness and integrity, safeguards threading, and prevents accidental damage. Pipe end caps are widely used across construction, plumbing, and industrial supply to ensure that pipes arrive on-site ready for installation without costly rework.
What makes EPDM caps better for outdoor sealing than PVC?
EPDM (Ethylene Propylene Diene Monomer) caps offer superior resistance to UV light, ozone, and extreme temperatures, making them the ideal choice for outdoor sealing. Unlike standard PVC, EPDM remains flexible in both hot and cold weather, is less likely to crack over time, and withstands harsh British weather conditions. This makes EPDM caps the go-to solution for electrical enclosures, outdoor pipework, and any external application where long-term sealing is required.
Are rebar protection caps mandatory on UK construction sites?
Yes, rebar protection caps are strongly recommended and, in many cases, required on UK construction sites to reduce the risk of impalement injuries. Health & Safety Executive (HSE) guidelines advise fitting high-visibility, mushroom-style caps to exposed rebar ends to protect workers and site visitors. Our rebar caps meet industry standards, providing both safety compliance and peace of mind on site.
What are flange cover caps and when are they used?
Flange cover caps are specialised end caps designed to fit over the face of pipe flanges. They protect the flange surface and bolt holes from damage, dirt, and moisture during shipping, storage, and installation. Flange cover caps are especially important in industries like oil & gas, water treatment, and process engineering, where maintaining the integrity of pipe connections is critical.
What's the difference between driveshaft caps and end caps?
Driveshaft caps are designed specifically to protect the ends of driveshafts or similar rotating components, often during transport, installation, or repair. They help prevent contamination and physical damage to crucial connection points. Standard end caps, on the other hand, are more general-purpose and are used to cover, seal, or protect the open ends of pipes, tubes, or posts across a range of applications. Choosing the right type of cap ensures your components stay protected and function as intended.
