Threaded Sealing Caps

These Threaded Sealing Caps, or 'Fluid Sealing Caps' as they are also known, are made from a high quality LDPE plastic. They come with a neoprene rubber disc, which is secured within the head of the cap, which allows for a full seal that can be easily tightened by hand.

Threaded Sealing Caps are great for protecting threads from the ingress of dirt or moisture. They also provide an air-tight seal for fluid or gas filled applications, helping to prevent leakage or air exposure during its employment, hence their wide usage inside a number of Liquid & Gas industries.

These Fluid Sealing Caps are a specialist component for the sealing of threaded barrels, pipes, or containers to prevent leakage and prevent the ingress of foreign substances. Each of these caps is available in a range of thread types to suit, these being BSP, UNF, and Metric.

Benefits of our Sealing Caps:

• Made from a high quality LDPE Plastic and Neoprene Sealing Ring
• Provides a strong seal compatible with fluids and gases
• Available in BSP, UNF, and Metric threads
• Easily tightened by hand
