ageing resistance vacuum hoses test


Connect the vacuum hand pump to the pressure sensor. Turn on the ignition. Set the multimeter to “DC voltage”. Set the lower absolute pressure value P-low. Test the lower output signal U-low between pin B (2) and earth A (1). Set the upper absolute pressure value P-high. Test the upper output signal U-high between pin B (2) and earth A (1).


adapter instead. Once the hose has been stretched, it may leak. 13. Tag hoses before disconnecting them: (a) When disconnecting vacuum hoses, use tags to iden­ tify how they should be reconnected. (b) After completing a job, double check that the vacuum hoses are properly connected. A label under the hood shows the proper layout.

Static Conductive and Static Dissipative Flexible Hose

Another factor that it important when choosing the right flexible hose to meet your requirements is electrical conductivity and static resistance. If a hose with the wrong electrical resistance rating is chosen, the potential for static sparks that could interact with dust particles and set off fire or explosions increases. To help decide which hose is appropriate for a specific situation
