New 5mm Expansion Plug

The Lee Company's new 5mm Short Betaplug is the latest addition to Lee’s 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. The unique, tapered design of this 5mm diameter expansion plug 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. The Short Betaplug is also offered in 7, 9, 11, 13 and 16mm diameters.
