Threaded Caps

 (2 product groups)

Threaded caps also known as threaded plastic caps, play a crucial role in protecting your component’s threads from damage, which can easily occur during handling at various stages, including manufacturing and transportation.

They are available in various thread sizes to ensure a precise fit. Threaded caps made from different plastic materials are particularly popular. Additionally, threaded plastic caps form an airtight seal to protect against moisture and other damaging elements that can corrode the part.

A threaded sealing cap is primarily used to protect the threads of a component and provide an airtight seal. One of its key functions is to prevent damage to the threads during handling, shipping, and storage, ensuring that the component remains in good working condition. Additionally, the cap provides environmental protection by sealing the component, which keeps out moisture, dust, dirt, and other contaminants that could lead to corrosion or other forms of damage.

Furthermore, a threaded sealing cap plays a crucial role in containment by keeping fluids or gases within a component, thereby preventing leaks. This is especially important in applications where maintaining the integrity of the contained substance is critical. The cap also helps in preserving the component's functionality by preventing exposure to harmful environmental elements.

Threaded Sealing Caps

Threaded Sealing Caps are designed for use with BSP and Gas Threads protect threads and fittings from damage during production, storage and shipping. Features an interior neoprene rubber sealing disc that limits fluid leakage and reduces possible shear. Used in hydraulic and pneumatic systems.

  • The cap is fitted with an internal neoprene rubber sealing disk to limit fluid leakage, plus it reduces potential shearing.
  • It is easy to install and remove by hand, but its hex head allows the plug to be applied or removed with a spanner or socket at low torque.
  • Used in various applications, including hydraulic, pneumatic and general engineering industries.
