Regularly used as replacement feet, these inserts work well with all kinds of round tubing which has been made for ground contact, acting as a foot when used in this kind of situation. When used as Round tube end caps, these are best suited for finishing uses such as a chrome tube finish, however they are also used for protection in larger tube diameters to cover pipe holes and similar applications. In some instances, these Round Plastic Inserts are available above 120mm, however you will need to look at some of our other listings to see all of the standard sizes which we have on offer.

Ribbed for a tight fitting, these inserts cover a wall thickness range which should be matched to your tube for a flush and proper installation. Also regarded as 'end caps' for round tubes, these are not to be confused with our end cap selection, which generally are fitted over the outside section.
Round Chromed Inserts
These Round Tube Inserts are offered with a chrome finished head, which work excellently with any chromed piece of tubing. Offering a flush and aesthetic finish, it is no wonder why these are one of the most popular solutions inside this range, especially for manufacturers who are looking to incorporate it in a product.

Round tube inserts, like other inserts come with ribs to fit across a range of wall thicknesses, providing an easier fit than other solutions.
Round Heavy Duty Inserts

Manufactured from PE rather than an LDPE, these have better strength under load, as a harder form of Plastic. As round tube inserts, these fit on the internal section of round tubing, for use as feet or to prevent ingress into an otherwise hollow piece of tube.
Round Threaded Inserts
Round Plastic Threaded Inserts, or threaded tube fittings as they can be known are a widely used part that work well with round tubes / holes due to their ribs which allow them to be slotted in and fixed with ease, whilst maintaining a tight fitting at all times. These are a plastic threaded tube insert solution that are extremely hard and durable therefore will work with a massive array of applications, each product has a number of thread options and sizes available with these standard plastic options with anything between M6-12 providing you with some of the strongest possible metal threads for your external attachment of threaded goods or products to fit inside your threaded tube insert. Threaded inserts or threaded tube ends as they are also called are good for use with a huge array of different tube sizes, lengths and shapes. Known as Tube Fixings for feet these work by insertion into a round tubular frame or section, with ribs to keep them tight in their position once fitted.
PTFE Insert Glides
These Insert Glides for tubes come with a PTFE base from standard, this promotes excellent gliding properties across a range of surfaces. Commonly used with carpet or even vinyl, PTFE resembles a popular consumer product in terms of teflon, a material which is regularly employed with frying pans to prevent sticking.

These Tube Glides for chairs come with a standard flat base topped with felt, this helps to reduce friction across surfaces and can be easily fitted to tubular Chairs/Furniture. Coming with a ribbed shank section, these fit securely and without the need for additional fasteners, fixings or adhesives. Unlike our other products, these Tubular Insert Glides can be installed onto almost any appliance, making them a popular choice over their nail on, or screw in counter-parts. In their more broad sense and categorically, these are referred to as Felt Chair Glides. Hence their main usage being with a tubular base chair leg, where they would be inserted to act as a foot type fitting.
