resistance to uneven settlement., as well as excellent high temperature resistance, low temperature
resistance and fire resistance.
5. Light weight, good bending performance, free length choices, simple installation.
Highlights of Product —— SAFE USE OF GAS FOR THE WHOLE FAMILY
| 01/ Protective sleeve,flame-retardant material Outer sleeve adopts insulating and flame-retardant material, which effectively prevents burning, and it is automatically extinguished without fire sources. |  |
 | 02/ SS304 hose, rat bite-proof The high-strength SS304 hose is with high pressure bearing, can also effectively prevent gas leakage caused by rat bites |
| 03/ Thick copper pipe, well connection seal The pipe fittings are made of HPb59-1 copper, electroplated surface, built-in sealing rings (NBR rubber), with excellent sealing performance. |  |
 | 04/ Super flexibility, bend at will The design of corrugated hose secures its very good flexibility, bend at will, convenient installation. |
| 05/ Air grooves The cover sleeve with air grooves can guide the leaking gas to flow to the detective hole at the connecting ends, for purpose of accurate monitoring. |  |
