Hydraulic Flange Fittings

The YH Hydraulic 4-bolt flange connections conform to SAE J518 and ISO 6162-1 and -2. Flanges are proven leak-free connections especially suited for larger sizes, higher pressures, and assembly in tight quarters.

Threaded port connections, such as SAE straight thread O-ring and ISO 6149, are easy to assemble and provide 6000 psi (and higher) pressure capability up to size 3/4” and 27mm (beyond 3/4” size the pressure rating decreases and assembly torques increase).

Compared to an equivalent size, threaded port YH Hydraulic 4-bolt flange connections require lower assembly torque; another advantage in tight quarters where wrench clearances are limited.

YH Hydraulic 4-bolt flange products are designed to provide different methods of connecting a tube, hose, pipe or fitting to the SAE standard 4-bolt flange ports.

Flange Fittings

All YH Hydraulic flange fittings (except for those with square mounting hole patterns – nomenclature code QS), are designed to conform to O-ring groove, bolt holes and bolt pattern dimensions of either Code 61 or Code 62 of SAE J518 and ISO 6162-1 (Code 61) or -2 (Code 62).

The flange adapters (Code Q1 and Q2), and flange block fittings (Codes Q1B, Q2B and QSB) have O-ring grooves conforming to dimensions in SAE J518. The flange block fittings (Codes Q1B and Q2B) have through holes for the mounting bolts conforming to SAE J518.

There is no industry standard for the bolt pattern of the square pattern block flanges with codes QSP and QSB. The flange pad fittings (Codes Q1P, Q2P, and QSP) have a flat face (no O-ring groove) and the mounting holes are tapped.

Applications

The hydraulic flange connection was developed as a large-sized high-pressure connection. While large-sized threaded connections require a very high assembly torque to resist high pressures, flange port connections divide the assembly torque among multiple bolts, each of which requires much less torque. Large threaded connections also present assembly difficulties especially where wrench clearance is limited.

In fact, flange connections provide for zero-clearance assembly that enables easy connecting, disconnecting and maintenance of tube-to-tube, tube-to-hose and manifold connections. Infinite positioning is a “built-in” feature, in that the flange can be positioned at any angle. In addition, flange connections have the highest resistance to loosening, due to the clamping load distribution over the flange head. This makes flange connections an ideal choice for bent hose end connections that are subjected to very high lateral forces that tend to cause loosening.
