2 – Ear Clamps are multi purpose clamps for maintenance, repair and service purposes. With this type of clamp, rubber hoses, plastic tubing, electrical cables, air hoses and other materials can be securely fastened. The geometry of the closed ears increases the effective clamping force and provides a degree of elasticity to accommodate changes in size of the parts being joined, such as may be caused by thermal expansion or vibration. Please note for perfect sealing, it is essential that the ears are correctly closed during installation.
