Threaded Plugs

Our Plastic Threaded Plugs are produced from a highly durable Low Density Polyethylene Plastic which allows for good protection of internal threads, preventing damage, moisture, corrosion and, dirt. Threaded Protection Plugs are especially useful within hydraulic and engineering related industries, where the cost of equipment outweighs the typically low cost of protection methods.

As an easy and efficient product to install, these simply screw into your desired thread with strong protection properties to prevent deterioration over time. This can be through liquid ingress or oxidisation. Finished in red, these are designed for easy visibility and removal, meaning that they can be used both during storage, transport or as general protection elements.

We stock these Threaded Protection Plugs in a number of different standard thread types, including BSP, Metric, and UNF. Each has a number of potential sizing options, ranging from M10 all the way up to M42, ensuring we always have the protection solution that you require. Please click through to your required thread type above before viewing all of the sizes available.
