Is the SPCRB polyurethane spiral air hose suitable for automotive pneumatic tools and safe to use at -40Â°C to +60Â°C?

Yes. The SPCRB polyurethane spiral air hose is suitable for automotive pneumatic tools and is safe to use across the stated temperature range. The hose is specifically designed for pneumatic control systems, hand tools and industrial robots and has been successfully used in the automotive industry. Its polyurethane (PUR) construction offers high flexibility even after long service life and resistance to abrasion, rupture and kinking. It is rated for working pressures up to 17 bar (depending on diameter) and an operating temperature range of -40Â°C to +60Â°C, so it will perform safely at those temperatures. Finished ends include straight sections (100 mm and 500 mm) with external BSPT threaded ends (no springs for 16 mm OD). Ensure you choose the correct diameter for your pressure and flow requirements and follow any installation and maintenance guidelines for fittings and pressure ratings.

Can the SPCRB polyurethane spiral air hose withstand continuous 17 bar working pressure without performance loss?

SPCRB polyurethane spiral air hose is specified with a working pressure "up to 17 bar (depending on hose diameter)". Whether it can withstand continuous 17 bar without performance loss depends on the specific diameter/version and application conditions. If the particular SPCRB model and diameter are rated for 17 bar, continuous use at that rated pressure is acceptable within the declared operating temperature range (â40Â°C to +60Â°C) and with proper fittings and installation. However, prolonged operation at the maximum rated pressure can accelerate wear; for maximum service life and safety a pressure margin (safety factor) below the absolute maximum is recommended. For definitive confirmation, verify the exact SPCRB diameter rating and manufacturerâs continuous-duty or burst-pressure data.

Does the SPCRB polyurethane spiral air hose require end springs for 16 mm outer diameter fittings?

No. the SPCRB polyurethane spiral air hose does not require end springs for 16 mm outer diameter fittings. The product description explicitly states the hose is finished with straight sections and external BSPT threaded ends without springs for an outer diameter of 16 mm.
