UNF Sealing Caps

Every one of our UNF Threaded Sealing End Caps are manufactured using a strong LDPE plastic and come with a specialised Neoprene rubber disc built-in to provide a tight seal. As a threaded component, these are most commonly used to seal off containers or barrels with a threaded hole, simply screwing into position to prevent ingress and leakage.

Also used to protect threads, these Sealing End Caps are a versatile component that are popular inside many industries, including Oil & Gas.

We keep a large stock of UNF Sealing End Caps in thread sizes between 1/4" and 1 7/8". However, we are always able to provide custom sizing or variants where required. For all currently available sizes or to request a free sample, please see the product table below.
