scope:

This specification covers general requirements, property and performance requirements, identification, quality, packing and shipping and source approval and quality control requirements.

Restricted Chemical Substances

All product supplied to the requirements of this specification must comply with the requirements of the MPAPS B-50 specification.

APPLICATION

This specification covers six types of hose, with end-fittings, used in the air brake, engine oil, diesel fuel, transmission oil cooling, low-pressure power steering, and coolant systems. Types I through IV and VI may be used in applications operating between -40° and 150°C (-40° to 302°F) which conform to the pressures and bend radii listed in Table 5. Type V may be used in systems operating between - 53° to 232°C (-65° to 450°F) which conform to the pressures and bend radii listed in Table 2. Type V may also be used in applications requiring extra chemical resistance, such as engine oil recirculation lines.

RESTRICTIONS:

Hose covered by this specification shall not be used in the following applications:

High-pressure power steering, cab-lift, or hydraulic brake systems.

Air brake jounce/articulating lines - see MPAPS F-6036.

Application in coolant systems is limited to Type VIII and to customer demand option only.
