Hydraulic Flange Fittings

SAE Code 61 and Code 62

Code 61 is intended for for pressures up to 3,000 psi. Code 62 is intended for up to 6,000 psi. Bolt hole spacing and flange head diameters are larger for the higher pressure Code 62 fittings.

The female port is an unthreaded hole with four bolt holes in a rectangular pattern around the port. The male fitting is a flanged head, grooved for an O-ring, and either a captive flange or split flange halves with bolt holes to match the port. The seal takes place by compressing the O-ring between the flanged head and the flat surface surrounding the port. The threaded bolts hold the connection together.
