Single Wire Seals

Single wire seals are a very common seal for automotive connectors and are available in two types: single wire seals and cavity plugs.

People often ask,What is the difference between Single wire seals and cavity plug?

Single Wire Seals

Single wire seals allow cables to pass through and surround the cable, providing waterproof and dustproof protection at critical interfaces. Cavity plugs block the cavity, preventing water, dust, and oil from entering the automotive connector.
