Adjustable ear type hose clamp 109 / 159 / 113 / 163 series

Choice of engagement positions: clamp can be adjusted to several nominal diameters Inner ring with radial guidance: effective and powerful all-round sealing Clamp ear: simple and fast installation, visible deformation provides evidence of proper closure Specially formed strip edges: reduced risk of damage to parts being clamped Material PG 109 zinc-plated steel band PG 159 & 163 Stainless Steel, Material no. 1.4301/UNS S30400 Corrosion resistance according to DIN EN ISO 9227 PG 109 ≥ 96 h PG 159 ≥ 1000 h PG 163 ≥ 1000 h Adjustable Clamps PG 109 Size range width x thickness 29.5 – 122.0 mm 7.0 x 0.8 mm 29.5 – 122.0 mm 9.0 x 0.8 mm Adjustable Clamps PG 159 Size range width x thickness 25.0 – 50.0 mm 7.0 x 0.8 mm* 40.0 – 110.0 mm 7.0 x 0.8 mm* Adjustable Clamps with radial guiding PG 163 Size range width x thickness 30.0 – 116.0 mm 7.0 x 0.6 mm 72.0 – 132.0 mm 9.0 x 0.6 mm Clamp ear (closing element) Using tools designed by Oetiker, the clamp is closed by drawing together the lower radii of the “ear”. The maximum diameter reduction is proportional to the open “ear” width (s).
