SAE 100R12 is a spiral-wire-reinforced hydraulic hose, available in sizes ranging from 3/8 inch to 2 inches.
SAE 100 R12 four-layer steel-wire spiral hydraulic hose is designed for conveying petroleum-based hydraulic fluids under high-pressure operating conditions, and is used in heavy industrial and commercial equipment such as excavators, loaders, and construction machinery.
It consists of three layers: an inner tube, a reinforcement layer, and an outer cover. The inner tube is made of oil‑resistant black nitrile rubber (NBR), ensuring excellent performance when conveying petroleum‑based hydraulic fluids. The reinforcement layer comprises four layers of helical steel wire, enabling the hose to withstand high‑pressure applications and extreme temperature conditions. The outer cover is crafted from synthetic rubber that offers superior resistance to abrasion, weathering, and corrosion. SAE 100R12 heavy‑duty hydraulic hoses feature four layers of helically wound steel wire reinforcement arranged in alternating directions, which effectively balances pressure and restraining forces. This helical wire reinforcement is particularly well suited for applications involving high pulse loads and severe abrasion, making it an ideal choice for harsh environments such as construction, mining, and the oil and gas industries. These hoses meet or exceed the performance requirements of SAE 100R12 and EN 856 4SH.
Structure: The hose consists of an oil-resistant synthetic rubber inner liner, four layers of steel wire spirals wound in alternating directions, and…
Composed of a single-layer oil- and weather-resistant synthetic rubber outer coating.
Application: Suitable for hoses used with petroleum-based hydraulic fluids, operating within a temperature range of -40°C to +100°C.
