This pre-assembled aluminum tapered expansion plug is engineered to seal fluid passages in metal castings, creating a leak-tight seal without the use of threads, O-rings, or sealants. Its unique tapered design eliminates the need for tight manufacturing tolerances and allows designers to minimize the wall thickness around the plug, even for brittle housing materials. The pre-assembled plug facilitates a reliable automated or manual installation process. It is ideal for high volume applications.
