The 87392 Flange 3000PSI represents a critical component in medium-pressure hydraulic systems, engineered specifically to provide secure, leak-free connections in applications operating up to 3,000 PSI. As a Code 61 flange per industry standards, this component is designed for systems where reliable pressure containment and efficient fluid transfer are essential. The 87392 flange facilitates the connection of larger diameter hydraulic lines, where traditional threaded fittings may not provide sufficient flow capacity or structural integrity. Its robust design and standardized dimensions make it a versatile solution across various industrial sectors, ensuring compatibility and performance in diverse hydraulic system configurations.
The 87392 Flange is rated for a maximum operating pressure of 3,000 PSI (207 bar), making it ideal for medium-pressure hydraulic applications across industrial and mobile equipment. It conforms to SAE Code 61 specifications, which define the dimensional requirements for four-bolt flange connections in hydraulic systems. This standardization ensures interchangeability with other Code 61 flange components from different manufacturers, simplifying system design, maintenance, and component replacement. The flange's flat face design with precision-machined sealing surfaces ensures uniform pressure distribution across the gasket, minimizing leakage potential.
Constructed from high-grade carbon steel, the 87392 Flange offers an optimal combination of strength, durability, and cost-effectiveness for medium-pressure applications. The flange face features a serrated surface finish that enhances gasket retention and improves sealing performance under pressure cycling conditions. Standard finishes include phosphate coating with oil dip for corrosion resistance during storage and initial operation. For applications requiring enhanced corrosion resistance, optional zinc plating or painted finishes are available to protect against environmental exposure in harsh operating conditions.
The 87392 Flange is available in sizes ranging from DN13 to DN127 (corresponding to 1/2" to 5" nominal pipe sizes), accommodating a wide range of flow requirements in hydraulic systems. It features a four-bolt pattern with standardized hole spacing that conforms to SAE specifications, ensuring compatibility with industry-standard flange clamps and hardware. The flange is available in both split flange and integral flange configurations to suit different installation requirements, with options for weld-on, thread-on, and socket-weld connections to accommodate various piping systems.
In industrial settings, the 87392 Flange is widely used in hydraulic power units, injection molding machines, and metal processing equipment. Its ability to handle moderate pressures while providing high flow capacity makes it ideal for main hydraulic lines in presses, stamping equipment, and material handling systems. The flange's robust construction ensures reliable performance in continuous operation environments where system downtime must be minimized.
The 87392 Flange finds application in medium-duty mobile hydraulic systems, including utility trucks, medium-sized excavators, and agricultural equipment. It is commonly used in hydraulic circuits for lift arms, hydraulic cylinders, and auxiliary equipment where reliable performance under dynamic operating conditions is required. The flange's standardized design simplifies maintenance and repair in field conditions, reducing equipment downtime for agricultural and construction operations.
In process industries such as pulp and paper, food processing, and material handling, the 87392 Flange provides reliable connections in hydraulic systems powering conveyor belts, mixers, and processing equipment. Its medium-pressure rating and high flow capacity make it suitable for central hydraulic systems that distribute power to multiple actuators, ensuring consistent performance across complex machinery configurations.
The 87392 Flange is specifically designed for medium-pressure applications up to 3,000 PSI as a Code 61 flange, whereas high-pressure flanges (Code 62) are rated for up to 6,000 PSI. The key design differences include flange thickness, bolt size, and gasket design—Code 62 flanges feature thicker construction and larger bolts to accommodate higher pressure loads. The 87392's design optimizes weight and cost for medium-pressure applications while maintaining the structural integrity required for reliable operation within its pressure rating.
The 87392 Flange is designed for use with SAE Code 61 gaskets, typically constructed from nitrile rubber, Viton®, or fiber-reinforced composite materials. The choice of gasket material depends on the hydraulic fluid type and operating temperature range. Nitrile gaskets are suitable for standard mineral oil fluids at temperatures up to 120°C, while Viton® gaskets are recommended for higher temperatures or synthetic fluids. Metal-reinforced gaskets are available for applications involving pressure spikes or where enhanced durability is required.
Proper installation begins with cleaning all flange surfaces and ensuring they are free from nicks, scratches, or debris that could compromise the seal. The gasket should be properly centered on the flange face without overhang. Bolts should be tightened in a crisscross pattern to ensure uniform pressure distribution, gradually increasing torque to the recommended specification. The recommended torque varies by bolt size but typically ranges from 30 ft-lbs for 1/2" bolts to 100 ft-lbs for 1" bolts. Final torque should be checked after initial system operation to account for any gasket compression.
While primarily designed to SAE Code 61 specifications, the 87392 Flange is dimensionally compatible with ISO 6162-1 standards for flanges in the 3.5 MPa to 35 MPa pressure range. This compatibility allows for integration with hydraulic components manufactured to international standards, facilitating global equipment design and component sourcing. When integrating with non-SAE components, we recommend verifying dimensional compatibility, particularly regarding bolt hole spacing and flange thickness, to ensure proper fit and performance.
Regular inspection should include checking for signs of leakage around the gasket, bolt tightness, and corrosion on flange surfaces. During scheduled maintenance, bolts should be retorqued to ensure they remain at specification, as thermal cycling and pressure fluctuations can cause gradual loosening. Gaskets should be replaced whenever flanges are disconnected, even if they appear undamaged, as reusing gaskets can compromise sealing performance. For systems operating in harsh environments, periodic cleaning and inspection for corrosion are recommended, with touch-up painting or coating applied as needed to maintain corrosion resistance.
