Sealing caps and protective caps are used to protect machines, pipes, and components from dirt, moisture, dust, and damage. They ensure that openings remain properly sealed, preventing contamination, leakage, and product loss. The caps are made of high-quality plastic and are available in various designs, colors, and sizes. Thanks to their versatility, they are widely used in the mechanical engineering, hydraulics, pneumatics, and transport sectors. Techniparts supplies a wide range of sealing and protective caps suitable for temporary protection during production, storage, or transport, as well as for permanent sealing in technical installations.
External protection, internal protection, screw caps (with or without thread), flange covers, grip caps, high-temperature caps, metric sealing covers.
Protection and sealing of pipes, tubes, valves, cylinders, pumps, and machines. Suitable for use during production, maintenance, transport, and storage.
Sealing caps and protective caps are mainly used on machines where it’s critical to keep dirt out. These caps close off the machine from contaminants, dents and moisture—giving you confidence that no debris can enter your product. Our caps are made from plastic and available in a wide range of types, sizes and colours, so there’s always a solution that fits your needs.
The types we can supply:
Threaded caps are essential for protecting products from dirt during production, storage and shipping. A key use is sealing containers and pipework—especially where liquid-tight integrity matters across many industries.
In systems and machinery, sealing caps play a crucial role thanks to their reliability. They help prevent leaks and product loss. One of the most common variants are metric sealing plugs/caps with thread. These threaded plugs limit fluid leakage across a wide range of applications. An integrated gasket helps prevent leaks. They are also resistant to chemicals and reduce shear. The hex head allows installation and removal with a wrench or socket, though we recommend final tightening by hand.
We offer a broad assortment of plastic tube/pipe caps, including open-end ventilation caps, closed-end caps and flexible caps that resist splitting and cracking. We also supply special protective caps such as piston rod caps and stator caps.
