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.
Standard series stepless ear clamps are especially well suited to both hoses and hard pipes.
The reinforced stepless series clamps are ideal for difficult to seal applications such as aluminum pipe and other pipes made of small elasticity materials, commonly used in the automotive industry.
PEX series stepless ear clamps are only well suited to PEX tubing.
Features 360°Stepless Design - no steps or gaps on inner circumference and narrow band design, providing concentrated seal compression.
Specially formed strip edges reduce the damage of the part being clamped.Lightweight with obvious clamping effect.
