Code 61 sae hydraulic flanges

Code 61 SAE hydraulic flanges are a form of hydraulic connection used in high-pressure hydraulic systems to connect hydraulic tubing or hoses. These flanges are manufactured to SAE J518/ISO 6162-1 specifications and are utilised in heavy machinery, construction equipment, and fluid power systems.

Stockist and supplier of Code 61 flanges

To produce a leak-free connection between hydraulic components, Code 61 flanges are utilised in conjunction with O-ring seals. They come in a variety of diameters and pressure ratings to satisfy the demands of various hydraulic applications. The flange is divided into two pieces, each with a flat face that matches with the other. When the bolts are tightened, an O-ring compresses between the two flat faces and seals the connection.

Code 61 flanges are often built of materials that provide strength and endurance in tough operating environments, such as carbon steel or stainless steel. They are often employed in applications requiring high pressure and high flow rates, and they are preferred for their dependability and convenience of installation.
