Lee 6 mm Short Betaplug

The 6mm Short Betaplug is a pre-assembled, tapered expansion plug specifically engineered to seal fluid passages leak-tight in metal and plastic housings, without the use of threads, sealants, or O-rings.

The unique, tapered design of the Short Betaplug features controlled expansion during installation that causes the lands and grooves on the O.D. of the plug body to bite into the wall of the fluid passage, creating a leak-tight seal and assuring retention. The tapered design also eliminates the tight manufacturing tolerances and extra machining necessary with cylindrical expansion devices or threaded plugs, and allows engineers to minimize the wall thickness required around the plug, even for brittle housing materials.

  • One-piece design – Facilitates reliable automated or manual installation
  • Controlled expansion – Ensures consistent performance – Eliminates cracking of brittle materials
  • No threads or sealants required – Designed to seal for life – No extra machining necessary
