The Oetiker® 2-Ear Clamp provides increased clamping range over the 1-Ear Clamp. The closed "ear" geometry provides an inherent retained load and a spring action in the clamp, permitting expansion and contraction during thermo-cycling or vibrating conditions. This is a robust, durable one-piece design that offers a positive, tamper resistant seal. Smooth edges prevent damage to hoses and the one-piece design offers quick and easy installation. Parts listed on this page are Electro-Zinc plated Carbon Steel only.
