Also frequently used instead of plastic plugs, these provide a better gripping, preventing them from falling out of the hole once installed, something that plastic isn't able to match without the use of additional fasteners or fixings. Also known as SIlicone Bungs or Rubber Stoppers, these plugs for high temperature uses are popular across all kinds of industries where heat is common-place. Used mainly over Plastic Plugs to prevent melting and issues down the line, rubber provides the flexibility and properties required to do any kind of masking/covering job.

They are made to fit universal sizes with a simple push fit. Also known as snap fit plastic hole plugs or plastic stoppers, these can be ideal for use whilst transporting or storing due to the quick nature that they can be fitted or removed from an object/panel and are fairly durable for their class.

These are recommended for an alternative to rubber stoppers, being a more cost effective and readily available product like many of our Plastic Plugs.
Washer Masking Plugs
Our Washer masking plugs are a top rubber plugs solution that are manufactured using a premium high temperature TPR. These work excellently as an alternative to a Silicone plug or rubber stoppers as they work essentially the same way by filling a hole, although these washer masking plugs come with the added feature of having a flange, this allows it to cover any exposed external components. Due to this flange these Rubber Plugs are especially useful for use with threaded holes and threaded applications as it prevents debris from creeping in through the gaps that can be left by rubber stoppers. These rubber plugs are perfect for use inside a number of industries, most importantly the powder coating, shot blasting and anodizing ones which regularly use high temperatures to coat, bake and cover parts which need coating. Industries that use these regularly are powder coating which widely coat threaded parts such as car alloys etc. These are used over our Plastic Plugs as they provide high temperature and heat-proof properties, something that Plastic isn't as efficient at doing unfortunately.
Pipe End Plugs
Pipe End Plugs are popular forms of plastic plugs, available in a huge range of sizes to fit a massive array of different pipe sizes. As a ribbed application these are able to provide just as much grip as some of our rubber plugs and rubber stoppers, holding itself tightly onto the inside of the pipe/hole. Being made from plastic these can frequently be regarded as cost effective solutions, preventing unnecessary damage or wear to your pipe/tube. Rubber stoppers are frequently used along-side these pipe end plugs to ensure that there is no ingress into the tube which can cause damage over time, the rubber providing the definite sealing that our Plastic Plugs cannot.
Finned Hole Plugs
Our finned hole plugs are one of our newest forms of plastic plugs. Available in a range of sizes these are an extremely popular form of plastic plugs, often used over fir tree plugs due to their fins which help to hold them in place. Used as a temporary solution rather than a permanent one these plastic hole plugs can be used to protect and fill holes, preventing ingress or damage over time. Often highly regarded for similar properties to rubber stoppers or rubber plugs these are manufactured using an LDPE plastic, this is a versatile material that provides both strength and flexibility. Each of these finned plastic plugs features a short pull tab on its head, preventing the need for additional tools to pick them out, especially when used with smaller holes. These are regarded as a temporary solution and therefore their price reflects that, being a majorly cost efficient part that costs fractions of what other products may cost to produce.
Tube End Plugs
Tube End Plugs are specifically made to plug or cap off the end of cardboard packaging tubes and are an excellent form of our Plastic Plugs. Being made to specific industry standard sizes, these work in the same way as rubber stoppers to plug and cap off the end of a tube. These Plastic tube end plugs are widely used plastic plugs inside a number of different industries as a widely disposable part, being thrown away once popped of the tube end. Most commonly used inside food manufacturing and production these plastic plugs are excellent for use as lids on food packaging or cardboard containers. They are easily installed and clip perfectly in to cardboard tubes as well as other higher-end solutions including plastic and even metal. Each of these plastic plugs has a slight flexibility to it, this allows it to bend slightly into position to provide a tighter, comfier fit to the tube that is is placed inside. Rubber Plugs are often used over these kind of tube ends as they are cheaper, however these are specifically designed for the use hence their popularity as they provide a nicer looking finish, along with an easier to use application that can be removed by hand rather than a tool.
