The Alemite 308730-A (AA862) is a robust hydraulic coupler engineered for high-pressure lubrication applications. Designed to provide secure, leak-resistant connections, it is indispensable for maintenance operations utilizing grease guns and lubrication lines in industrial environments.
Key Specifications and Features:
– Operating Pressure Rating: Specifies the maximum safe operating pressure, engineered to withstand extreme forces in high-pressure lubrication systems up to 10,000 psi.
– Female Thread Specifications: Features a precision-machined 1/8 inch NPTF(f) (National Pipe Taper Fuel, female) thread, ensuring a secure and leak-resistant connection to compatible grease guns and lubrication lines.
– Compact Design Profile: Engineered with a narrow type fitting profile, allowing for easier access and operation in confined or hard-to-reach lubrication points.
– Advanced Sealing Technology: Incorporates a durable rubber seal, working in conjunction with the triple jaw assembly to maintain a leak-proof connection and prevent lubricant bypass during transfer.
– Integrated Check Valve: Equipped with a built-in check valve, which helps prevent backflow of lubricant and ensures a clean, efficient lubrication process by maintaining pressure.
– Positive Connection System: Utilizes a triple jaw assembly that securely grips and locks onto hydraulic fittings, providing a quick, positive, and stable connection crucial for efficient lubricant transfer.
