Eaton H11505-550R Oil-resistant Air Hose 5/16 in Id 550 Ft

Product Description

The EATON H11505-550R is an oil-resistant air hose designed for compressed air delivery in industrial, mechanical, and trade service environments. Built from Buna-N nitrile rubber, it resists petroleum-based oils and fluids that would degrade standard rubber hoses. The hose measures 5/16 inches inside diameter and 21/32 inches outside diameter, with a 300 psi working pressure rating. It handles a temperature range of -40 degrees F to 160 degrees F, making it suitable for both cold-climate outdoor work and heated shop environments. This hose is sold in cut-to-length increments from a 550-foot coil, with a 25-foot minimum cut length. Licensed contractors and shop technicians who need to run custom hose lengths will find this a practical bulk source.

This hose fits compressed air systems in automotive service bays, HVAC shops, plumbing contractors, and light industrial facilities. The oil-resistant construction makes it especially appropriate where hoses are routed near compressor oil, lubricants, or hydraulic fluid. It has no end connections, so it is cut to the required length and fitted with the appropriate field-installed fittings. Typical applications include runs from a compressor manifold to tool drops, pneumatic control lines, and general shop air distribution.

• Sold in 1-foot increments from a 550-foot coil, 25-foot minimum cut

Compatibility

Designed for use in compressed air distribution systems requiring an oil-resistant hose. Compatible with standard field-installed pneumatic fittings sized for 5/16 inch ID hose. No specific OEM system compatibility is stated by the manufacturer for this product.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system requirements. Depressurize the air supply line completely before cutting or connecting the hose. Use fittings and clamps rated for the working pressure of the system, and verify all connections before restoring pressure. Inspect the hose routing to avoid sharp bends, pinch points, or contact with surfaces that exceed the rated temperature range.
