American Safety Standard Stainless Steel 304 Flexible Gas Tubes
1.According to GB/T14525/2010
2.Remove the impurities and splash and guarantee weld appearance
3.Dense waves on both ends of the hose
4.Working pressure 25 bar,working temperature -20~130 degrees
Celsius
5.Firstly Spray one layer of anti-rust primer on the surface of the
carbon steel,
Then spray on imitation plating silver metallic paint,do not spray
on sealing
Surface,but wipe with anti-rust oil
6.Note:Down groove butt on welding ring position
Product Features

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. |  |
