FUNCTIONAL APPLICATION — OETIKER EAR CLAMP CRIMPING:
Required tool for proper installation of Oetiker ear-style hose clamps. The Oetiker jaw geometry on this tool ensures correct crimping force and angle to compress the clamp "ear" without damaging the clamp band or hose. Standard pliers will NOT properly crimp Oetiker ear clamps — the precise jaw geometry of dedicated Oetiker pliers is essential for a proper, leak-free seal.

• Johnson/Evinrude Fuel and Oil Hose Service
