Apache 39038972 5/8" Female O-Ring Boss x 1/2" Male Pipe Hydraulic Adapter Brass The Apache 39038972 hydraulic adapter (Style 6404) enables reliable, leak-resistant connections between hydraulic components by converting a 5/8" female O-ring boss (ORB) port to a 1/2" male pipe thread. Constructed from durable brass, this adapter withstands high-pressure fluid transfer in industrial, commercial, and agricultural hydraulic systems. The 5/8"-18 UNC female ORB end provides a positive seal with an O-ring (not included), while the 1/2"-14 NPT male pipe thread ensures secure, tapered sealing in standard hydraulic circuits. Ideal for adapting hoses, valves, cylinders, or pumps with mismatched ports, this compact fitting supports maintenance, repair, or customization of existing hydraulic assemblies without requiring full system replacement. Features - Converts 5/8" female O-ring boss (ORB) to 1/2" male NPT pipe thread - Brass construction offers corrosion resistance and compatibility with hydraulic fluids - Female ORB end ensures O-ring-sealed, high-pressure integrity (O-ring not included) - Male pipe thread conforms to standard NPT sealing for reliable fluid containment - Compatible with Style 6404 (E220-R 6404-10FORB-8MP) hydraulic specifications - Compact size (2 x 3 x 5 in) fits tight machinery layouts and control panels - Suitable for industrial machinery, agricultural equipment, and mobile hydraulics - Reusable design supports system modifications and serviceability - Smooth machined finish reduces turbulence and pressure drop - Single-unit packaging for immediate use in field or shop repairs Specifications - Brand Name: Apache - Model Name: Apache 39038972 - Part Number: 39038972 - Product Type: Hydraulic Adapter - Style: 6404 - Material: Brass - Connection 1: 5/8" Female O-Ring Boss (ORB) ? 5/8"-18 UNC - Connection 2: 1/2" Male Pipe Thread (NPT) ? 1/2"-14 NPT - Thread Type: Unified Coarse (ORB), National Pipe Taper (NPT) - Sealing Method: O-Ring (ORB side, not included), Thread Sealant (NPT side) - Product Dimensions: 2 x 3 x 5 in - Item Weight: 0.25 lb - Packaging Type: Bulk - Quantity per Package: 1 - Application: Hydraulic Fluid Systems ? Industrial, Agricultural, Commercial - Country of Origin: China - UPC: 843276389726 - Global Trade Identification Number: 00843276389726 - Manufacturer: Apache Product Application This hydraulic adapter is used by mechanics, equipment operators, and maintenance technicians to integrate or repair hydraulic circuits where port standards differ?such as connecting an ORB-equipped cylinder to an NPT-threaded hose or valve block. Common in tractors, skid steers, log splitters, and factory machinery, it allows quick adaptation without custom hoses or costly component swaps. The brass body resists degradation from petroleum-based hydraulic fluids and provides reliable performance in moderate-pressure applications. Its precision threading ensures repeatable, leak-free assembly, making it a practical, cost-effective solution for field repairs, system upgrades, or prototype hydraulic setups.
