Advanced 87311/87611 SAE Code 61/62 Flange Hydraulic Hose Fitting

The 87311 / 87611 Series is a heavy-duty fluid connection component specifically engineered for high-pressure hydraulic architectures requiring robust flange-based connections. Featuring a precision-machined flange head design with an integrated O-ring groove, this fitting is available in both Code 61 (3000 PSI) and Code 62 (6000 PSI) configurations. Secured via split flange halves and bolts, it delivers exceptional clamping force and eliminates traditional threaded joint failure points under extreme dynamic pressure impulses.

Core Hydraulic Advantages

High-Pressure Flange Security: Designed for high-flow, high-pressure lines where threaded connections are impractical, utilizing split flange clamps to distribute clamping load evenly and prevent separation under severe stress.
O-Ring Face Seal Dynamics: The grooved flange face houses an elastomeric O-ring that compresses against the mating port surface, providing a positive, leak-proof seal that withstands heavy system vibration and shock pressure spikes.
Exceptional Blowout Resistance: Precision CNC-machined from your choice of premium high-strength carbon steel or corrosion-resistant 304/316 stainless steel, delivering maximum pull-out resistance, dimensional stability, and burst-proof performance under severe pressure spikes.

With optional zinc-nickel alloy surface treatment available to significantly extend service life, this hydraulic hose fitting ensures maximum longevity, structural safety, and leak-proof performance for heavy-duty industrial fluid power networks.
