3mirrors Allison Transmission Cooler Lines & Fittings Adapters Heavy Duty, Braided Hose Compatible with GM GMC Chevy LBZ LMM Allison Duramax Transmission Lines(2006-2010)
  • Suitable for 2006-2010 GM Chevy GMC with 6.6L LBZ LMM duramax diesel engine, only for allison transmission.‎
  • The CONTINUOUS SERVICE TEMPERATURE RANGE is -40 °F / 257 °F (-40 °C / 125 °C). 58 Bar / 840 PSI working pressure; 232 Bar / 3,360 PSI Min burst pressure.
  • Multi-layer protection, oil-resistant synthetic rubber on the inside of the tubing, a layer of anti-textile braid in the middle, and a durable synthetic rubber on the outside to protect the hose from wear.
  • Strong resistance to high pressure. After the oil is fully heated, Duramax will not exceed 300 psi at worst. This hose can withstand a working pressure of 840 psi and a burst pressure of 3360 psi. Far beyond our requirements.
  • With strong resistance to high temperature, the transmission of the driving vehicle will get warmer, and the temperature will be very high. Our hose temperature range is -40°F/257°F (-40°C/125°C). Usually high-pressure-resistant pipes cannot withstand high temperatures. Exceeding the temperature will lead to a sudden reduction in life.
