Deadman Twin Sensing Hose, Series 7139

Brand: Parker Hannifin

Deadman Twin Sensing Hose is designed for transfer of air to operate aircraft fueling control system applications to 200°F and 200 psi, Series 7139.

Parker's Series 7139 Deadman Twin Sensing Hose provides excellent service in industrial and commercial applications to safely and quickly shut down unattended equipment in emergency situations. 

The chemically bonded dual hoses provide easier hose management and handling than independent single lines. 

The color coding allows easy identification for quick and accurate installation, the cover resists abrasion, oil and weathering, and the hose is qualified with permanent crimp couplings for a safe and secure connection.
Features
  • Tube: Black nitrile for air/oil mist compatibility to 200°F. 
  • Reinforcement: Multiple textile plies for strength and durability. 
  • Cover: Green/red chloroprene for resistance to abrasion, oil and weathering.
