Is it dangerous to use welding hose
1. Flexibility: Poly Air Hose Beats PVC in Cold Weather
Flexibility matters for easy air hose use, especially outdoors. PVC air hoses turn rigid in cold temperatures (below 10℃). They crack easily if you bend or drag them in the cold, which stops air flow. Poly air hoses, however, stay flexible even in freezing conditions (down to -20℃). You can twist or move a poly air hose around tools or workbenches in winter without kinking. This makes poly air hoses better for cold garages, construction sites, or outdoor projects.
2. Durability: Poly Air Hose Resists Wear Longer
Both air hoses handle basic tasks, but poly air hoses last longer. PVC air hoses scratch or split easily if they rub against concrete, metal, or sharp objects. Their material breaks down faster under UV light too—leaving a PVC air hose in sunlight for months makes it brittle. Poly air hoses have stronger resistance to scratches, UV rays, and impact. A well-maintained poly air hose can last 5 to 7 years, while a PVC air hose typically lasts 2 to 3 years with the same use.
3. Cost and Weight: PVC Air Hose Is Cheaper, Poly Is Lighter
If budget is your top concern, PVC air hoses are better. They cost 20% to 40% less than poly air hoses—great for occasional use (like small DIY projects). But poly air hoses are lighter: a 10-meter poly air hose weighs about 1.5 kg, while a PVC one of the same length weighs 2.5 kg. This lightness makes poly air hoses easier to carry around job sites. For frequent or heavy use, poly’s light weight and durability justify the higher cost; for casual use, PVC offers good value.
