C (flange O.D.) and Dim. D (bolt spacing) match the SAE J518 Code 61 standard exactly, so these fittings bolt directly onto any Code 61 flange port. The -RW suffix denotes the braided-hose version; for spiral-wound hose, use series 87312-XX-XXRW.<\/p>\n<h3>Why Flange Connections for Big Lines<\/h3>\n<p>When the hose bore grows beyond about DN32, threaded connections become heavy, awkward and hard to torque reliably. The four-bolt flange solves this: the joint is clamped with four bolts, the O-ring on the flange face carries the seal, and the connection is assembled with ordinary wrenches instead of torque multiplication tools.<\/p>\n<p>This SAE flange fitting 3000 psi is the standard solution for pump suction and discharge lines, valve manifold connections and reservoir lines in mobile and industrial hydraulics. The Code 61 flange pattern (3000 psi series) is the most widely used flange standard in the world, so this fitting mates directly with existing flange ports without adapters.<\/p>\n<h3>How the Flange O-Ring Seals<\/h3>\n<p>The flange face of this fitting carries an O-ring groove. When the four bolts are tightened, the O-ring is compressed between this flange face and the mating flange face of the port. The O-ring, not the metal faces, carries the seal. This is the same face-seal philosophy as the ORFS system, scaled up for large bores and high flow rates.<\/p>\n<p>The seal tolerates minor surface scratches on the flange faces, withstands high impulse pressure without loosening, and can be serviced by simply replacing the O-ring. Our impulse testing found that flange assemblies hold pressure cycling reliably across the full temperature range.<\/p>\n<h3>Profondeur d'insertion et diam\u00e8tre ext\u00e9rieur du sertissage : les deux chiffres demand\u00e9s par les ing\u00e9nieurs<\/h3>\n<p>La profondeur d'insertion correspond \u00e0 la longueur de la partie cannel\u00e9e qui p\u00e9n\u00e8tre dans l'al\u00e9sage du tuyau.
