What Are Threaded Sealing Caps?

Threaded sealing caps are specialised protective caps that screw directly onto threaded parts to shield them from contaminants and accidental damage. The addition of an internal neoprene sealing disc enhances sealing performance and allows these caps to maintain system integrity in harsh conditions. Their effectiveness at keeping out liquids, debris and environmental agents makes them a trusted solution for demanding engineering applications, including systems under pressure or where tight tolerances must be maintained.

Who Uses Them in the UK?

These threaded sealing caps are a common sight across UK industries, especially with engineers, technicians and buyers working in automotive, mechanical, fluid power and equipment servicing sectors. Production teams use them to seal off threaded sections before components are installed, while distributors and logistics staff rely on them to protect fittings in transit. They're often selected for quality control procedures where sealing integrity is crucial.
