Lee Betaplugs are economical one-piece tapered expansion plugs developed for high-volume production applications. This component is designed to seal fluid passageways in both metal and plastic housings. Therefore, it can be used with a wide range of materials. Additionally, the installation process is straightforward, involving no screws, threads, sealants, or O-rings – meaning it can easily be performed with a manual or automated process. Finally, its tapered design eliminates the need for tight manufacturing tolerances, ideal for high-volume applications and perfect for brittle materials or thin wall conditions.
The 6000 Series Betaplug is built for high-pressure automotive systems. Design the 6000 Series Betaplug into systems up to 7000 psi, and choose from parts that range from 4 mm to 8 mm in diameter.
The 7mm 6000 Series Lee Betaplug® Expansion Plug is a pre-assembled, one-piece, tapered expansion plug specifically engineered to seal fluid passages in metal castings leak-tight, without the use of threads or sealants. Controlled expansion during installation 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 unique tapered design eliminates the need for tight manufacturing tolerances, and allows the designer to minimize the wall thickness required around the plug, even for brittle housing materials.
