Thermoid Cobra 1-1/4" ID 250 PSI Fuel Oil Delivery Hose NBR 159 Ft w/ Fittings

Thermoid Cobra 1-1/4" ID 250 PSI Fuel Oil Delivery Hose NBR 159 Ft w/ Fittings

This is a 159-foot coil of Thermoid Cobra industrial fuel oil delivery hose with a 1-1/4" (1.25") inner diameter and a 250 PSI working pressure rating. The Cobra line is Thermoid's petroleum-service hose built for fuel oil transfer applications, constructed with an NBR (nitrile rubber) tube and a blended NBR/PVC cover — both rated RMA Class A for petroleum compatibility. The hose is reinforced with four spiral plies of polyester yarn for pressure retention and flexibility. The coil includes a brass threaded coupling at one end and a galvanized tee fitting with brass union connections at the other.

Applications

Thermoid Cobra fuel oil hoses are used in petroleum transfer and delivery operations — most commonly for heating oil delivery trucks, bulk fuel transfer stations, and stationary fuel oil distribution systems. The NBR (nitrile) tube material resists aliphatic petroleum products including fuel oils, diesel, and heating oil, making it the standard construction for this class of service hose. RMA Class A designation means the tube meets the Rubber Manufacturers Association's highest rating for petroleum oil resistance. The four-spiral polyester reinforcement allows the hose to handle the working pressures typical of pump-driven fuel delivery while remaining flexible enough to reel and unreel in the field. Hoses in this configuration — with a tee fitting at one end — are often used in tanker truck delivery setups where the tee allows simultaneous connection of a meter, valve, or vapor recovery line alongside the main delivery path. The 250 PSI working pressure is appropriate for most commercial fuel oil pump discharge pressures encountered in heating oil and diesel delivery service.
