Is the High Pressure Thermoplastic Measuring Hose TEST 8, 089 Micro Bore suitable for bicycle hydraulic brakes and rated to 412–500 bar?

Yes. The High Pressure Thermoplastic Measuring Hose TEST 8, 089 Micro Bore Format is suitable for bicycle hydraulic brakes and is rated to operate at extreme working pressures in the 412–500 bar range (actual rating depends on specific hose type and diameter). The hose’s inner polyester/polyamide layer with a single aramid braid reinforcement provides the necessary strength, while the abrasion-resistant outer layer and proven impulse-cycle durability (e.g., DN2 polyamide ZC-TEST8-5021PA completed 1,000,000 cycles) confirm suitability for demanding hydraulic brake applications.

Can the High Pressure Thermoplastic Measuring Hose TEST 8, 089 Micro Bore handle vacuum conditions down to 0.93 bar and repeated impulse cycles like the DN2 polyamide version?

Yes. High Pressure Thermoplastic Measuring Hose TEST 8, 089 Micro Bore is specified to withstand vacuum conditions down to 0.93 bar and, based on the product description, is designed for demanding, high-cycle applications. Its inner layer (polyester or polyamide) with a single aramid braid provides the high strength required for extreme working pressures (412–500 bar), and the construction includes an abrasion-resistant, micro-perforated outer layer suitable for gas media and mechanical stress. The DN2 polyamide version (ZC-TEST8-5021PA) has proven durability with one million impulse cycles; while that specific test refers to the DN2 PA variant, the TEST 8, 089 Micro Bore is described as intended for similar high-performance, repeated-impulse use and is rated for the same vacuum limit and wide temperature range (−40°C to +100°C, +70°C for water/air). Therefore it can handle vacuum down to 0.93 bar and is engineered for repeated impulse cycles comparable to the DN2 polyamide version.
