Straight NPT Male Thread Hydraulic Pipe Fittings And Adapters National Standard
Product Description
STANDARD TOLERANCE
National standard GB1800.1-2009 will determine the standard tolerance level of size accuracy is divided into 18 grades, respectively using IT1, IT2,...... IT18 representation. From IT1 to IT18, the corresponding tolerance values increase sequentially, and the accuracy decreases.
The dimensional accuracy obtained by cutting is generally related to the equipment, tools and cutting conditions used. The higher the dimensional accuracy, the more complicated the process of the parts, the higher the processing costs. Therefore, in the design of parts, should ensure the use of parts under the premise of, as far as possible the use of lower dimensional accuracy.
