1. DEFINITION OF A FITTING The adapter is a junction component between a pipe or a hose and a hydraulic or pneumatic device. Five aspects are required to identify an adapter : MATERIAL SIZE SEALING MODE THREAD SHAPE 1.1 SHAPE There are 5 general adapter shapes : They are complemented by features, the most common ones being : (FS x M) Swivel Female x Male (F x F) Female x Female (Coupling)

1.2 MATERIAL The following elements must be taken into account to select the type of materials for adapters and their seals : - the hydraulic device environment, - the chemical corrosiveness and temperature of the fluid to be carried, - the standards and the regulation. We propose adapters made of Steel + bichromated zinc, Stainless steel (on request) and Brass (on request). 1.3 SEALING MODE There are four typical sealing modes : a) Sealing in the threads NPT FAMILY Addition of a sealing product b) Sealing cone / cone BSPFAMILY Sealing zone c) Sealing by interlaying a seal ORFS seal O ring...

d) Sealing with 24° ring 1.4 THREAD There are four main thread families : - BSP, GAS - JIC, SAE (UN, UNF) - NPT - METRIC (ISO) 1.5 SIZE The size may be indicated in inches or in millimetre depending on the thread. For further information, refer to the technical pages giving details on standards. However, it is advisable to pay attention to the fitting designation so as to avoid mistakes. Example: S MJIC 3/4 x MBSPBS 3/4 The 3/4" notion on BSP and JIC does not mean that the threads have the same dimensions on both sides of the fitting.

2. TECHNICAL DEFINITIONS 2.1 WORKING PRESSURES(PN) The indicated values correspond to maximum working pressures in bar (10 bar = 1 MPa) for a temperature ranging between -40° C and 100° C and for steel parts used with an oil-based hydraulic fluid. In a normative way, the maximum working pressure corresponds to the bursting pressure divided by a safety factor of 4. Unless otherwise specified in our catalogue, the maximum working pressure of an adapter corresponds to the lowest working pressure on either side in the considered operating conditions or in the most conservative case. Example :...

2.2 TIGHTENING TORQUES The indicated values correspond to maximum tightening torques in N.m for steel adapters. 2.3 MATERIALS a) STEEL The most commonly used grades or their equivalents according to the production site are : PRODUCT ANTI-CORROSION TREATMENT Zn8C (CR3) NF ISO 150 2081 8μm thick bichromated zinc plating with trivalent chromium (1) Welding adapters Stainless steel and brass adapters on request. (1) : Our manufacturing batches before 2008 may be bichromated with hexavalent chromium (Chromium VI). TEMPERATURE RANGE Acrylonitrile Butadiene Hydraulic oils, greases, hydrocarbons,...
