How push-style expanders work
Koenig push-type expansion plugs are installed using a hardened setting tool with a standard press, air-hammer or Express 3000/5000 hydropneumatic table press. Using expander technology, a ball is pressed into the serrated sleeves to form a tight seal. No adhesives or sealants are required, as this creates a 100% metal-to-metal seal.
