At Perfect Engineers, we offer robust and reusable Cap and Plug fittings under our trusted brand PE-LOCK. These single ferrule fittings are designed to seal off unused ports or tube ends, ensuring system safety during shutdowns, testing, or line isolations — without the need for welding or permanent blocking methods.
Manufactured for high-pressure, leak-free performance, our PE-LOCK Caps & Plugs are widely used in instrumentation, hydraulic, chemical, gas, and aerospace systems where temporary or permanent sealing is required with maximum reliability.
Both fittings use single ferrule compression technology to provide reliable sealing, reusability, and quick installation without tools or sealants.
