Tear Tab Caps

Tear Tab Caps are a standard, off-the-shelf solution that will allow you to meet your customers demands without those all too common time delays.

Tear Tab Caps are quick-fit and quick-release caps. As a rapid solution, they can be easily fitted and removed across an array of applications, including; critical hydraulic tubes and pipes, such as those that carry oils and other fluids around vehicles and machineries. This makes them an ideal choice for the specialist vehicle manufacturing industry, and other automotive and manufacturing sectors.

Tear Tab Caps also assist in the protection of tube and pipe ends during transportation and storage. They protect parts from damage, dirt, moisture and other forms of ingress. These caps are highly versatile, and ideal for a range of applications and different threads, including; BSP, GAS, UNF, JIC and NPT.

Made from Low Density Polyethylene (LDPE), the caps feature a simple tear-away tab for quick release, and fast removal. The ease of extracting the Tear Tab Cap from the hydraulic pipework makes the removal process faster. By simply pulling the tab, the cap splits open, tearing away.

The LDPE material is tough and flexible. They provide many of the advantages of PVC caps, such as integrity and cleanliness.
