KAS Cascade Gas Connection Flex Hose
KAS cascade gas connection flex hoses are professional installation components that safely connect condensing boilers or combi boilers arranged side by side in high-capacity heating systems (central systems) to the main gas line.
These products are specifically designed to speed up installation and ensure system safety.
Key Features
-
Material: Made of corrosion-resistant AISI 316L or 304 stainless steel hose.
-
Yellow sleeve (shrink): The outside of the hose is covered with a yellow polyolefin-based jacket that protects against chemical cleaners and external influences.
-
Vibration damping: Absorbs vibrations generated by the appliances in the cascade system during operation, preventing connection points on the main line from loosening.
-
Flexibility: Unlike rigid pipes, it easily tolerates millimetric misalignments between appliances.
Technical Details and Dimensions
Cascade systems usually require higher gas flow rates, so pay attention to diameter and length when selecting:
| Specification | Details |
|---|---|
| Connection Sizes | Usually starting from DN25 (1"); larger sizes are available as needed. |
| Standard Lengths | Depending on installation needs, longer options than burner flex hoses are available (e.g. 30 cm, 40 cm, 50 cm). |
| Connection Type | Options with a nipple (male) on one end and a union (swivel nut) on the other, or nipples on both ends, are available. |
