141C... NOVA 4 - SAE 100R4 SUCTION RETURN - MSHA COVER

Tube : Seamless oil resistant black nitrile rubber resistant to products with up to 50% aromatic content. Reinforcement : Steel wire helix embedded between layers of high tensile synthetic cords plus built-in static wire. Cover : Heat, abrasion, and weather resistant black chloroprene rubber. MSHA approved. Temperature Range : -40°C (-40°F) to 125°C (257°F).

NOVA 4 is designed for hydraulic suction and low pressure return lines and suitable for use with fuels, mineral oils, and other petroleum derivatives. The nitrile rubber tube offers superior resistance to soft ening and swelling sometimes caused by high temperature oils and is designed to withstand products with up to 50% aromatic content. The helical wire reinforcement allows for full vacuum service while the corrugated construction results in excellent in-hand flexibility.
