SAE J1475_201406 standard is for Hydraulic Hose Fitting for Marine Applications.
SAE J1475 covers general and performance specifications for hydraulic hose fittings of the styles, types, and classes defined in Section 3 and used in conjunction with nonmetallic flexible hoses for marine applications. This document does not ensure compatibility between manufacturers of hydraulic hose and hydraulic hose fittings. Compatibility is the responsibility of the hydraulic hose assembly manufacturer.
SAE J1475 references standards as follows:
SAE J51 6—Hydraulic Hose Fittings
SAE J51 8—Hydraulic Flanged Tube, Pipe and Hose Connections, Four-Bolt Split Flange Type

Types of SAE J1475 Fittings shall be of one of the following types: male dryseal pipe thread, male SAE straight thread O-ring boss, male 37 degree flared, female 37 degree flared, male 45 degree flared, female 45 degree flared, male flareless, female flareless, male metric straight thread O-ring boss, face seal, or 4-bolt split flange connections. A fitting type may consist of more than one class of fitting.
Material of SAE J1475 fittings For bars, forgings, tube, and pipe, material shall be steel. Elongation in 50 mm shall be no less than 10%. Split flange clamp halves shall be made of a ferrous material with a tensile strength of at least 31 0 N/mm 2 and an elongation in 50 mm of no less than 6%. Castings may be used only for clamps and split flange clamp halves.
