ISO 5675 Standard
ISO 5675 is based on ISO 7241 Type A but is specifically designed for agricultural machinery. It standardizes 1/2″ and 3/4″ body sizes and includes additional performance requirements. In real-world applications, Pioneer-brand agricultural couplers set the industry benchmark, and most manufacturers follow these dimensions to ensure interchangeability across brands. And the body size covered from 1/4″ to 1″.
Some customers mistakenly buy ISO A quick couplings instead of ISO 5675 replacements. While the 1/2″ size is usually compatible, other sizes may not fit. To ensure the right choice, we recommend measuring the diameter and length of the first section of the male connector. This simple step helps quickly identify the correct quick coupling type and prevents mismatched purchases.
