The ISO 2037 standard does not directly provide specific parameter specifications for quick connect fittings. ‌
The ISO 2037:1980 standard mainly focuses on metal pipes and fittings, especially stainless steel pipes used in the food industry, rather than specific parameters for quick connect fittings. This standard provides specifications for the size, material, and other related technical requirements of stainless steel pipes, but does not specify the specific parameters of quick connect fittings, such as connection size, material, and pressure rating.
Quick connect fittings are commonly used in industries such as dairy and food, and their control diameters follow international industrial standards such as DIN, ISO, SMS, 3A, IDF, etc. The materials are usually stainless steel 304, 316, 316L. The inner and outer surfaces of these joints are usually treated with high-end polishing equipment to achieve surface precision requirements, suitable for industrial fields such as dairy products, food, beer, beverages, pharmaceuticals, cosmetics, etc.
