OETIKER - Stepless Ear Clamps
Oetiker Stepless Ear

OETIKER Stepless Ear Clamps (Product Group 167)

The term "Stepless" refers to the absence of steps or gaps on the inner circumference of the clamp. The stepless® design provides uniform compression and a 360° seal. Quick fit with a single crimp makes this range perfect for OEM's.

Standard series Stepless® Ear Clamps are especially well suited to applications involving both flexible and inflexible thin-walled hoses.

Number 1  Visual check that clamp is closed.

Number 2  360° Stepless® Design - no steps or gaps in inner circumference

Number 3  Specially formed strip edges reduce the risk of damage to the part being clamped.

Number 4  Narrow band, concentrated seal compression.
