What is the relationship between hose length and water flow rate
PU air hose and PE air hose are common pneumatic tools, but their material traits and applications differ greatly. Below we break down the key distinctions to help you choose wisely.
1. Material Flexibility & Durability
PU air hose is made of polyurethane, offering exceptional flexibility even in low temperatures. It bends easily around tools or workspaces without kinking. PE air hose is stiffer; it resists bending and may crack if folded repeatedly. Additionally, PU air hose boasts better abrasion resistance—ideal for rough job sites. PE air hose is more prone to wear from friction with concrete or metal.
2. Temperature & Pressure Tolerance
PU air hose handles a wider temperature range, from -20℃ to 60℃, making it suitable for indoor and outdoor use. It also withstands higher working pressure (up to 15 bar typically), fitting heavy-duty pneumatic tools. PE air hose has narrower temperature limits and lower pressure capacity (around 10 bar). It works best in mild, low-pressure environments like small workshops.
3. Weight & Practicality
PU air hose is lightweight, reducing user fatigue during long hours of operation. Its soft texture makes it easy to carry and store. PE air hose is heavier and bulkier, which hinders portability. Moreover, PU air hose has better chemical resistance to oils and solvents common in industrial settings. PE air hose may degrade faster when exposed to such substances.
4. Cost & Use Case Fit
PU air hose is slightly more expensive, but its longevity and versatility justify the investment for professionals. It shines in construction, auto repair, and manufacturing. PE air hose is budget-friendly, suited for light tasks like home DIY or small-scale inflation. For frequent, heavy use, PU air hose remains the more reliable choice.
