Single ear clamp, also known as single ear infinite clamp, refers to the absence of protrusions or gaps on the inner ring of the clamp. The infinite design achieves uniform force compression on the surface of the pipe fittings and 360° sealing guarantee.
The standard series of single ear infinite clamps are suitable for connecting general hoses and hard hoses. The reinforced series are suitable for situations where sealing is difficult, such as connection of pipe fittings with low elasticity. The PEX series is specifically designed for PEX pipe connections.
