What We Sell

Trebork specialise in plastic end caps and plastic bungs available in a variety of shapes and colours. We supply injection-moulded plastic end caps which are specifically designed to seal profiles, tubes, hollow section, box sections, and pipes. Our plastic end caps come in black, grey, and white.
Our plastic bungs are made with an external piece that protrudes beyond the plastic profile, as well as an internal piece called a core, that has been hammered into the centre of the profile. The matt structure of the upper part of the plastic end cap gives it an aesthetic appearance. The plastic caps and plugs come with a rough surface finish designed to prevent scratching and damage in collective packaging.
The lower part of the end cap consists of a core and protruding ‘lamella’. When the end cap is hammered in, the lamella adjusts to the thickness of the tube wall.

Quality Guaranteed

The plugs we sell are made from polyethylene which offers universal appeal and a number of application possibilities. Polyethylene is known for its low abrasion and resistance to corrosion from environmental stress. It’s also got high dimensional stability at low temperatures, good chemical resistance, low water absorption and is resistant to changing weather conditions and UV radiation.
Polyethylene is a material that is completely physiologically inert, therefore it is fully approved for contact with food.

A Variety of Uses

Our plastic end caps and plugs are widely used in steel profile structures, metal tubing, pipes, box sections, tubes, hollow section, chair legs, chair foot, bench foot, fencing systems, some machines and devices, workshop furniture, playground equipment and other elements of garden architecture. They are used in the furniture, machinery, electrical engineering and construction industries.
