A Nitrogen Gas Hose 20 Bar (300 PSI) is a high-pressure industrial hose specifically engineered for the safe transfer of gaseous nitrogen. Although nitrogen is chemically inert, its high operating pressure requires a hose construction that ensures strength, durability, and long-term safety.
A standard 20 Bar nitrogen gas hose is typically constructed :
Inner Tube
Manufactured from high-quality synthetic rubber such as EPDM or SBR, designed to resist the drying effect of nitrogen gas. The inner tube is non-porous, minimizing gas permeation and maintaining pressure integrity.
Reinforcement Layer
Reinforced with high-tensile synthetic textile or braided fiber, providing the structural strength required to withstand a working pressure of 20 Bar. The hose is designed with a safety factor, achieving a burst pressure typically 3 to 4 times the working pressure.
Outer Cover
Made from durable synthetic rubber, commonly yellow or black for easy identification. The cover is pin-pricked (micro-perforated) to allow any permeated gas to escape safely, preventing blistering or bubble formation within the hose wall.
