This is a new 40-foot coil of Sealfast SAE 100R1AT hydraulic hose with a 3/4-inch inside diameter and a 1,250 PSI working pressure, as printed directly on the hose cover. SAE 100R1AT (equivalent to EN 853 1ST) is a single-wire-braid reinforced rubber hydraulic hose designed for medium-pressure petroleum-based and water-glycol hydraulic fluid service; the "AT" designation specifies a thin, flexible outer cover with a wrapped textile braid over the wire reinforcement. The "fxs" suffix indicates a fiber-cross-spiral inner liner construction for improved flexibility and kink resistance versus standard R1AT, making this hose well-suited for mobile hydraulic equipment, agricultural machinery, and construction equipment where repeated flexing occurs. The hose is supplied as a raw cut length without end fittings, ready for field assembly with standard JIC, BSPP, or NPT crimp or reusable fittings sized for 3/4-inch 100R1 hose.
