FERRULE FOR SAE 100R1AT – R2AT / DIN EN 853 1SN – 2SN / SAE 100R16 SAE 100R17 For an SAE 100R1AT 1SN hose, a common type of coupling used is the one-piece crimped fitting. This fitting is specifically designed to match the dimensions and requirements of the SAE 100R1AT 1SN hose. The SAE 100R1AT 1SN hose is a medium-pressure hydraulic hose commonly used in various applications. It has a single high-tensile steel wire braid reinforcement and is suitable for operating pressures up to 2,250 psi (15.5 MPa). The coupling for this hose typically consists of a fitting that is crimped onto the hose using a hydraulic crimping machine. The crimped fitting ensures a secure and leak-free connection between the hose and the equipment it is being connected to.
