MAXIN JOINT®header CCH type is a header used for pipes for heating. The connection method with the heat source device uses a CCH clip. By combination with MAXIN JOINT®series, work efficiency is improved.
Header CCH type 4P
Header CCH type 2P
1.Realizing lighter weight
70% lighter than metal products. Improve work efficiency!
2.Foregoing the need for thermal-insulation material
Enhanced thermal insulation effect by special attributes of plastic
Simple design
3.Providing freeze-fracturing preventive function→Operating Manual Of Freeze-fracturing Preventive Function
The header is not broken even though the water inside is frozen.
4.Delivering CCH clip compatibility
Enable to attach to the heat source device with CCH clip

Added freeze-fracturing preventive function enables being used in cold areas.
| (1) Ordinary use condition The product is delivered with a condition as shown by the photo to the right. |
|
| (2) When the function was activated If the water being frozen inside, the knob moves downward and make the space inside to prevent the header from fracturing. *Please do not remove C ring. |
|
| (3) How to return to the original position After having confirmed the water inside is not frozen, push the knob up by hand. （You feel light click when completion.) Note 1) Please ensure that resetting is only completed by the person in charge. |
