Is the Measuring hose, thermoplastic for high pressure TEST 8, 089 MICRO BORE suitable for use with air and water up to +70Â°C and vacuum down to 0.07 bar?

Yes. The Measuring hose, thermoplastic for high pressure TEST 8, 089 MICRO BORE is suitable for use with air and water up to +70Â°C and for vacuum down to 0.07 bar. The hose is designed for hydraulic oil, water-based fluids and gas media (outer micro-perforated layer), its specified operating range for water and air is up to +70Â°C, and it has vacuum resistance stated up to 0.93 bar (i.e. capable of vacuum down to approx. 0.07 bar). Note that temperatures above ~80Â°C may shorten service life.

Can the Measuring hose, thermoplastic for high pressure TEST 8, 089 MICRO BORE withstand continuous temperatures of +100Â°C for oil-based hydraulic fluids?

Measuring hose, thermoplastic for high pressure TEST 8, 089 MICRO BORE can operate at continuous temperatures up to +100Â°C, but with caveats: the product description states temperatures above +80Â°C may reduce hose lifespan. The specified operating temperature range is -40Â°C to +100Â°C (with a note that for water and air the upper limit is +70Â°C). For oil-based hydraulic fluids +100Â°C is within the stated maximum, yet prolonged exposure at that temperature may shorten service life. If long-term reliability is critical, consider operating below +80Â°C or consult the manufacturer for endurance data at +100Â°C with your specific oil.

Can Measuring hose, thermoplastic for high pressure TEST 8, 089 MICRO BORE be used for gas media due to its micro-perforated outer layer?

Yes. Measuring hose, thermoplastic for high pressure TEST 8, 089 MICRO BORE can be used for gas media. The product description explicitly states the outer layer is microâperforated, allowing use with gas media. Additional relevant points from the specification: - Designed for hydraulic oil, waterâbased fluids and other media, and explicitly indicated for gas use due to microâperforated outer layer. - Vacuum resistance up to 0.93 bar (suitable for many lowâvacuum applications). - Operating temperature range: â40Â°C to +100Â°C (note: for water and air the upper recommended limit is +70Â°C). Temperatures above 80Â°C may shorten hose life. - Working pressure 412â500 bar depending on diameter/typeâsuitable for highâpressure gas applications within rated pressure. - Construction: polyester or polyamide inner layer, single aramid braid reinforcement, outer layer of abrasionâresistant polyurethane or polyamide. - DN2 polyamide version (ZC-TEST8-5021PA) passed 1 million impulse cycles, indicating good durability. Recommendations: ensure the specific hose variant and diameter chosen meet your gas pressure, temperature and safety requirements, and confirm compatibility of gas type with inner layer materials (polyester/polyamide). If you require use at temperatures above +70Â°C with air/gas or specific regulatory approvals for gas service, verify with the manufacturer.
