How to distinguish between counterfeit vulcanized tubes and genuine vulcanized tubes

Flame-retardant high-temperature vulcanized tube, also known as silicone hose, is covered with silicone fiberglass and supported internally by spiral steel wire. It is formed by a single high-temperature vulcanization at 300 degrees. The tube body is wear-resistant, with a smooth surface, no stains, no wrinkles, no roughness or uneven spots. The elastic steel wire and fiberglass thread pitch match, and it is uniformly wound. It features standard caliber, smooth inner wall, low wind resistance, light weight, smooth bending, strong elasticity and flexibility, strong UV resistance, strong corrosion resistance, environmental friendliness, non-toxicity, flame retardancy, and a white inner wall with no impurities, ensuring it will not be dyed when material passes through.
