5、es, air wipers, and air seats), and in fuel lines. This tubing is restricted to use in a temperature range of -40 to 93C (-40 to 200F) and to a maximum working pressure of 1034 kPa (150 psi). Tubing used in the fuel system is also controlled by TMS-7134. 2.0 SCOPE This specification covers the gener
6、al requirements, property and performance requirements, quality control and KCC requirements for two types of non-metallic tubing. 2.1 Type A: This is a non-reinforced tubing for use in secondary air system applications outside of the primary braking system. 2.2 Type B: This is a reinforced tubing t
7、hat may be used in the primary braking system as well as other air system applications and in the fuel system. NOTE 1: These tubing types should not be used for compressor discharge lines or in other applications where temperatures exceed 93C (200F), or pressures exceed 1034 kPa (150 psi). NOTE 2: S
