The Parker Stratoflex 111-20 Hose is a large-diameter medium-pressure aerospace hose engineered for dependable fluid transfer in aircraft systems requiring high flow capacity and reliable performance. Manufactured to Parker Stratoflex OEM standards, this hose is designed to withstand the demanding conditions encountered in aviation applications while providing excellent flexibility, durability, and pressure integrity.

Featuring a -20 size, the hose has a 1.125-inch nominal inside diameter and a 1.250-inch outside diameter. It is rated for a maximum working pressure of 600 PSI, making it well suited for applications involving high-volume fluid transfer where lower operating pressures are required. Its reinforced construction provides resistance to vibration, pressure cycling, abrasion, and mechanical wear while maintaining the flexibility needed for installation in aircraft structures and equipment compartments.

The 111-20 hose is compatible with approved Parker Stratoflex reusable and permanent hose fittings, allowing technicians to fabricate reliable OEM-quality hose assemblies for maintenance, repair, and overhaul operations. Proper routing, installation, and routine inspection for abrasion, leakage, aging, or physical damage are essential to maintaining system reliability and extending service life.

Commonly used in commercial, military, and general aviation platforms, the Parker Stratoflex 111-20 hose delivers dependable fluid transfer performance for hydraulic return lines, lubrication systems, fuel systems, and other aircraft applications requiring a durable large-bore aerospace hose.
