Fittings
Red Oak Hydraulics carries a large line of both one-piece and two-piece fittings to meet all of your coupling needs. Our extensive line of hydraulic fittings is available in both carbon and (upon request) stainless steel up to two-inch. Our hydraulic fitting line has a vast array of options for leak-free solutions.
Hydraulics have become progressively more complicated. Pressures are getting higher and hoses are getting smaller to accommodate tighter spaces. Hose information is usually printed on the layline of the original hose. If markings on the side of the hose are not visible it will be cut to determine the diameter and pressure rating. Additional information from the customer will also help us select the proper size and pressure. After hose has been assembled it is checked for proper tolerances.
