Lee 5 mm Short Betaplug

The 5mm Short Betaplug is the latest addition to our line of pre-assembled, one-piece, tapered expansion plugs specifically engineered to seal fluid passages in metal and plastic housings leak-tight, without the use of threads or sealants.

Lee 5mm Short Betaplug

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.

  • One-Piece Design: Facilitates reliable automated or manual installation
  • Controlled Expansion: ensures consistent performance and eliminates cracking of brittle materials
  • No Threads or Sealants Required: Reliable seal for life and no extra machining necessary
