Applicable Scenarios: 
Connects the outdoor gas main/riser to the inlet of the in-home gas meter.
Connecting the gas meter outlet with the indoor gas piping system.
Scenarios where it is necessary to cross a wall, pass through a casing or compensate for minor displacements such as foundation settlement.

Advantages: 
Safe and reliable: Stainless steel material is corrosion and pressure resistant and meets strict safety regulations for gas transportation.
Flexibility: Easy connection between the gas meter and the fixed piping, allowing small angle adjustments and compensation for small displacements (e.g. thermal expansion and contraction or slight settlement).
Long service life: not affected by humid environment, not easy to age, maintenance-free.
Strong sealing: Specialized fittings ensure absolute airtightness at the connection with the gas meter and the pipeline.
Standardized: Standard lengths and connection specifications are usually available for easy installation and replacement.
