Constructed from steel, this adapter is built for hydraulic and fluid system applications where a leak-free seal between an O-ring face seal port and a tapered pipe thread is required. The 6404 Series is engineered for dependable performance in demanding hydraulic environments. At 0.08 pounds, the fitting is compact and lightweight, measuring 1.2 inches in height and 0.7 inches in length. Licensed tradespeople and fluid power technicians use this adapter to transition between two common fitting standards without modifying existing porting or plumbing.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for residential and commercial hydraulic systems, mobile equipment, and industrial fluid lines where ORB-to-NPTF transitions are required. The Female O-Ring Boss end mates with a standard SAE O-ring port, providing a reliable static seal. The Male NPTF end threads into tapered pipe-thread ports per Dryseal standards, allowing a metal-to-metal seal without additional sealant in many installations. Typical applications include hydraulic power units, cylinders, manifold blocks, and related steel pipe adapter assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch Female O-Ring Boss inlet provides a positive, leak-resistant static seal at the port face\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch Male NPTF outlet meets Dryseal tapered pipe thread standards for metal-to-metal sealing\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in hydraulic and high-pressure fluid system service\u003c\/li\u003e\n  \u003cli\u003eStraight adapter configuration simplifies inline port-to-pipe transitions\u003c\/li\u003e\n  \u003cli\u003eCompact form factor  -  1.2 inches tall, 0.7 inches long  -  fits tight plumbing envelopes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for hydraulic systems using 5\/16-inch Female O-Ring Boss ports and 1\/8-inch Male NPTF pipe connections.

Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the O-ring and seating surface for damage before assembly, and thread the NPTF end carefully to avoid cross-threading or galling the steel threads.
