Oetiker Stepless Ear Clamp – Range 12.0 – 14.5 mm (0.472″ – 0.371″)
Oetiker Stepless Ear Clamps are made of UNS S30400 or DIN 1.4301 stainless steel.
Selecting the correct size : Select the nominal size nearest to, but always larger than the outside diameter of the material to be clamped. The outside diameter should be determined with connection fully assembled. Note: multiple barb fittings may require the use of a larger clamp size than single barb fittings – to consider the clamp closed – the ear width should be reduced by at least 40% when pinched.
