The assembly is connected to the oil port through a stud end pipe joint with a hard pipe/conduit or with a hose connector and a hose. GB/T 9065 aims to standardize the technical requirements of hydraulic transmission hose connectors and consists of six parts. --- Part 1.End seals. The purpose is to determine the basic requirements and dimensions for the design and performance of hose connectors with O-ring end seals. Inch requirements. --- Part 2.24° cone. The purpose is to determine the basic requirements and dimensional requirements for the design and performance of hose connectors with 24° cone seals. --- Part 3.Flange type. The purpose is to determine the basic requirements and dimensional requirements for the design and performance of flange type hose connectors. --- Part 4.Stud end. The purpose is to determine the basic requirements and dimensional requirements for the design and performance of hose fittings with stud ends. --- Part 5.37° flared type. The purpose is to determine the basic requirements and dimensions for the design and performance of 37° flared hose connectors Require. --- Part 6.60° cone. The purpose is to determine the basic requirements and dimensional requirements for the design and performance of hose connectors with a 60° cone. Hydraulic transmission connection hose connector Part 2.24° cone1 ScopeThis document specifies the basic requirements and dimensional requirements for the design and performance of hose connectors with 24° cone seal (in accordance with GB/T 14034.1). This type of hose connector is made of carbon steel and is used with hoses with a nominal inner diameter of 5mm~38mm. NOTE For hose fittings for hydraulic and pneumatic brake systems of road vehicles, see ISO 4038, ISO 4039-1 and ISO 4039-2. The hose connectors specified in this document (see Figure 1 for a typical example) are used in hydraulic systems together with hoses that meet the requirements of different hose standards.
