Understanding SAE 100R2 Specifications

The SAE 100R2 standard covers the construction for high-pressure hydraulic rubber hose designed to carry hydraulic fluids. The construction typically consists of an inner layer, a reinforcing layer, and an outer layer. The inner layer is usually made of synthetic rubber, which provides excellent fluid compatibility for hydraulic oils.

The reinforcing layer is crucial for maintaining pressure and preventing hose collapse under high pressures. It is often made of braided steel wire, which gives the hose its strength and durability. The outer layer serves as protection against abrasion and environmental damage, usually constructed from weather-resistant rubber material.
