This is a new NRP Jones 5/16 inch (7.9 mm) SAE 100R5-6 rubber air brake hose, part number 52684, manufactured March 2014 in the USA, sold here as a 39-foot cut length. The hose is rated to 2250 PSI working pressure and meets both SAE J1402 and U.S. DOT air brake hose standards, qualifying it for use in compressed-air brake systems on trucks, trailers, and buses. SAE 100R5 construction consists of an inner synthetic rubber tube, a textile braid reinforcement layer, and a braided textile outer cover — the "-6" dash size designator confirms the 5/16-inch (7.9 mm) nominal inside diameter. The "AII" designation is the SAE J1402 Type A, Grade II classification, indicating compatibility with petroleum-base brake fluids and air under the required impulse and high-temperature test cycles. Approved for OEM and aftermarket heavy-duty vehicle air-brake plumbing, primary and secondary circuits, and related pneumatic service lines.
