Parts and Material：

Body : CW617N or CW614N, in accordance with requirements of UNE-EN15.875

Ring: Antioxidant Pex-a

Superiority：

1.    The joint is much tighter, and the stress on the head part of the fitting and the ring is equal.

2.    The installation tools for the series are compatible with the present tools in the industry of overseas market.

3.    The series are free of O-ring.

Parts and Material：

Body : CW617N or CW614N, in accordance with UNE-EN15875-3

Ring: HPb58-3

Superiority：

1.    rotation design of the head part of the fittings allows the product to keep its product characteristics and avoid the leakage after the installation.

2.    The special bevel design of the ring can greatly reduce the friction coefficient during the installation, and the material caused by the head of the fittings and the ring during the pressing at the same time.

3.    The products have obtained CSTB certification in France.

 Parts and Material：

Body : CW617N or CW614N, in accordance with UNE-EN 15875

Ring: AISI 304

Ring protective seat: PP

Superiority：

1.    The 6-layer serrated design of the head provides better tightness of the product.

2.    The chamfer of the head part provides perfect transition for water flowing from the pipe to the fitting, which reduces water flow resistance and the sediments at the same time.

3.    The ring is made of AISI 304, designed in accordance with the mechanical pressing formability and marked the diameter and thickness of the pipe. The ring has 3 observation holes to guarantee the proper installation of the pipe.

4.    The ring protective seat is made of polypropylene, which fixes the ring and provides easy press connection while the pipe inserts the ring.

Parts and Material：

Body : CW617N or CW614N, in accordance with UNE-EN ISO 21003

Ring: AISI 304

O-ring：EPDM

Plastic seat: PP

Superiority：

1.    The serrated design of the head provides the perfect tight connection of the pipe and the fittings.

2.    The chamfer of the head part provides perfect transition for water flowing from the pipe to the fitting, which reduces water flow resistance and the sediments at the same time.

3.    O-ring used on the fittings is made of peroxide vulcanizing high compression EPDM 70% in accordance with UNE EN681-1 and UNE EN 682-2, which can provide the perfect tightness for the product. It also meets requirements of DVGW W270 food standard.

4.    The ring is made of AISI 304, designed in accordance with the mechanical pressing formability and marked the diameter and thickness of the pipe. The ring has 3 observation holes to guarantee the proper installation of the pipe.

5.    The ring protective seat is made of polypropylene, which can prevent the electricity conducting to the fittings through the aluminum layer and in the meantime fix the ring and provide easy press connection while the pipe inserts the ring.
