Features & Application Scenarios
The EPDM outer cover resists ozone degradation and thermal ageing. Combined with polyester braid reinforcement, the hose maintains good flexibility even under low-temperature conditions. Pre-fitted with quick coupler and 5/8 UNF threaded fittings, it enables fast, tool-free installation and disassembly.
It is widely used for transfer of helium, nitrogen and other inert gases. Typical use cases cover industrial gas delivery systems, laboratory gas pipelines and welding supporting gas circuits. Strict production and inspection standards ensure safe operation in diverse working environments.
Frequently Asked Questions
Q1: What inert gases can this rubber hose transfer?
A1: It is mainly designed for helium and nitrogen, suitable for most common inert gas delivery work in industrial and laboratory environments.
Q2: What pressure ratings should be followed during operation?
A2: Rated working pressure is 12 bar /175 psi. Never exceed this working pressure; minimum burst pressure reaches 36 bar /525 psi for safety margin.
Q3: What temperature range can this inert gas hose withstand?
A3: Operating temperature ranges from -40ºC up to +120ºC, adapting to cold ambient and workshop high-temperature conditions.
Q4: What fittings come with this hose assembly?
A4: It comes with 5/8 UNF threaded fitting and quick coupler, supporting fast connection without extra tools for welding and lab gas systems.
Q5: What standard lengths and colors are available?
A5: Standard roll lengths are 50 m and 100 m. Multiple color options including black, red, yellow, blue, green, orange are available for selection.
