stainless steel 37-degree flare tube fittings meet all design and performance requirements for 37-degree flare tube fittings in Standard J514 published by the Society of Automotive Engineers (SAE). This design was originally founded as a JIC (Joint Industrial) design, and was later adoped by the SAE to assure dimensional interchangeability between various manufacturers worldwide. OneHydraulics also offers a wide variety of pipe fittings and adapters, including straight thread adapters, male and female pipe fittings, male to female pipe adapters, and straight thread to pipe adapters. Our hydraulic tube fitting and adapter part numbers are constructed from symbols that identify the series, size, material and type of product. When ordering part numbers, begin by listing the series followed by the size and the material suffix. Sizes are measured in sixteenths of an inch (example: 4/16 or 4). The standard product is produced in steel and requires no material suffix. If ordering stainless steel products, add the suffix SS, and if you are ordering brass products, add the suffix B. Metric Bite Type Fittings are called out by tube size (in millimeters) i.e. 20mm Tube (S20), while Metric Port Fittings are called out by Thread O.D. and Thread Pitch (in millimeters) i.e. 30x2.0 or 30x1.5. BSPP fittings, while different from U.S. threads are still measured fractionally and are therefore called out by sixteenths of an inch.
