Flanged Caps

Flanged Caps are designed for easy assembly and removal, either with automated equipment or by hand. Typically used to protect metric or imperial threads, with or without O-Rings. The larger flange allows for faster application and removal when using it by hand.

For the purpose of quality control; the natural coloured caps allow you to see through the cap and check whether the O-ring is installed, or not installed, on the protected fitting.

Provides a snug and secure fit.

  • Designed to cover and protect threads.
  • Protects from damage, dirt, and moisture.
  • Used in the automotive and engineering industries.
