LEE IMH 5mm Short Betaplug ® The Lee Company’s new 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. 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. Design - Facilitates Reliable Automated or Manual Installation ■ Controlled Expansion - Ensures Consistent Performance - Eliminates Cracking of Brittle Materials ■ No Threads or Sealants Required - Reliable Seal for Life - No Extra Machining Necessary ACTUAL SIZE Maximum Passage Diameter PART NUMBER Known Boss Stress Conventional, cylindrical shaped expansion plugs require additional expansion for the clearance between the plug O.D. and the installation hole. The matching tapers of the Betaplug and its installation hole create a perfect fit, eliminating the need for additional expansion. Since the Betaplug's expansion is precisely controlled by the size of the tapered pin, the amount of expansion and any resulting boss stress is completely predictable. All dimensions in millimeters, except where noted. pressures may be higher depending on specific application requirements. Contact your Lee Sales Engineer for higher pressure requirements.

industrial microhydraulics The installation hole for the 5mm Short Betaplug has an included taper angle, Beta, of 4.3°, which matches the tapered outside diameter of the Short Betaplug. This included draft angle of 4.3° is very easy to achieve with a core pin in a die-cast or molded part, or to machine using a tapered tool. A tolerance of ±0.3° on the taper angle of 4.3° is specified to guarantee that the Short Betaplug’s rated performance is achieved. If the taper angles are out of tolerance, the plug will either wedge first at the top or at the bottom, reducing sealing burst pressure....
