O-ring face seal SAE J1453 fittings are popular in hydraulic lines onboard off road vehicles such as tractors, combines and other heavy equipment used in mining and construction. Due to the frequent vibration and actuation of components in off-road vehicles, it is extremely important to reduce or eliminate the number of potential leak points and incidences of leakage.
The SAE J1453 standard for ORFS fittings covers dimensions, threads, fitting and O-ring materials, and performance requirements of for use in hydraulic applications, as well as the interface of the O-ring face and nut portion of hose stem assembly.
A common, yet critical application for SAE J1453 ORFS fittings is with turbine flow meters in hydraulic fluid applications. A turbine flow meter is used for volumetric total flow and flow rate measurement. When the fluid flows through the meter it moves turbine blades that are free to rotate about an axis along the centre line of the turbine housing, monitoring flow rate.
