Threaded Caps and Plugs

Cost effective threaded caps and plugs used mainly in the hydraulics, automotive, radiator, valve manufacturing, and oil and gas industries.

You can order our threaded caps and plugs from the table directly below. However if you have larger volumes to look at, please contact us for bulk pricing.

There is a comprehensive selection of BSP, Metric and UNF sizes. In addition to the standard colours, BSP caps are usually manufactured in red or yellow LDPE, however they can be made in any colour* to suit the application.

The durable low density polyethylene material protects against damage, dirt, moisture and corrosion. As a result, this helps with storage and shipping and general protection.

Our threaded plugs and caps are reusable and the polyethylene is widely recyclable, therefore are environmentally friendly.

Please call or email us if you need help to with any technical or sizing queries and do not hesitate to contact our technical sales advisors who are always ready to help. 

We can also provide material and sizing specifications should you require this.
