MAXIN JOINT® : CCH, CCH Joint

Header CCH Type(RoHS compliance)

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

Features

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

Operating Manual Of Freeze-fracturing Preventive Function

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.
Note 2) Please ensure that resetting is completed without the use of tools (hammer, driver, etc.).
Note 3) Please note that this function is activated when the inner pressure is more than 8kgf.
