What is ISO 8434-1 - 24° cone connectors about?
ISO 8434 is a series of metallic tube connections for fluid power and general use. Metallic tube connections connect runs of tubing (for in-line, offset, multi-port, and mounting configurations) to other tubing sections, pipe, hose, or other components.
ISO 8434-1 is the first part of the ISO 8434 series of documents that specifies the general and dimensional requirements for 24° cone connectors using the cutting ring and O‑ring seal cone (referred to as DKO) suitable for use with ferrous and non-ferrous tubes with outside diameters from 4 mm to 42 mm inclusive.
These connectors are for use in fluid power and general applications within the limits of pressure and temperature specified in ISO 8434-1.
ISO 8434-1 also specifies a performance and qualification test for these connectors.
Who is ISO 8434-1 - 24° cone connectors for?
ISO 8434-1 on metallic tube connection is useful for:
- Pipe connector manufacturers
- Design engineers
- Quality control personnel
- Research and development facilities
Why should you use ISO 8434-1 - 24° cone connectors?
In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosed circuit. In general applications, a fluid may be conveyed under pressure. Components may be connected through their ports by connections (connectors) and conductors (tubes and hoses). ISO 8434-1 discusses tubes that are rigid conductors and hoses that are flexible conductors.
These connectors provide full-flow connections in hydraulic systems operating to the working pressures as shown in ISO 8434-1. Because many factors influence the pressure at which a system performs satisfactorily, these values are not intended to be understood as guaranteed minimums. For every application, sufficient testing is meant to be conducted and reviewed by both the user and manufacturer to ensure that required performance levels are met. Using ISO 8434-1 you can specify the general and dimensional requirements for 24° cone connectors.
