Compact one-piece clamp: for robust, secure connections, miniature sizes Clamp ear: fast and simple installation, visible deformation provides evidence of proper closure Deburred edges: reduced risk of damage to parts being clamped With insert Pre-shaped insert: effective and powerful all-round seal Material PG 153 Stainless Steel, Material no. 1.4307/UNS S30403 PG 154 Clamp: Stainless Steel, Material no. 1.4307/ UNS S30403 Insert: Stainless Steel, Material no. 1.4310/UNS S30100 Corrosion resistance according to DIN EN ISO 9227 PG 153 ≥ 800 h PG 154 ≥ 800 h Size range PG 153 3.3 – 30.7 mm PG 154 2.9 – 30.0 mm Process The manufacturing process for Oetiker 1-Ear and 2-Ear Clamps commences with the spiral roll-forming and welding of raw material into lengths of tube, a technique developed to obtain a robust, continuous welded ring. Oetiker 1-Ear Clamps with insert This type of clamp combines the geometry and properties of the 1-Ear Clamp with an insert made of stainless steel. These clamps are ideal for demanding applications involving soft or hard rubbers and plastics. The thin-walled insert ring (up to 0.3 mm thick), with an oval protrusion that locates in the ear space, bridges the ear gap and ensures almost uniform compression around the whole circumference of a clamp. Edge condition Burrs generated during the shearing and forming processes are entirely eliminated in a barrel-finishing operation.
