Threaded oil ports
In general, when the diameter of the orifice is less than 25mm, we choose the threaded oil port. The three most commonly used standards for threaded oil ports, are.
- Metric threads with a tooth angle of 60°, whose thread feature designation is indicated by M
- Inch threads with a 55° thread angle and a G thread feature code.
- U.S. threads with a 60° tooth angle, whose thread feature designator is denoted by UNF.

Metric threaded oil port (ISO 6141.1-2022)
Inch BSP threaded hole
BSPP threaded ED seal oil port (ISO 228-1)
American NPT threaded hole(GB/T12716&ANSIBI.20.1-1983T)
Inch PT thread hole(GB/T7306&IS07/1-1983T)
Flange oil port
When the diameter of the orifice is greater than 25mm, the flange oil port is selected. It is not that there is no large size threaded joint, but that large size threaded joint you need a very large wrench to screw, and also requires a large operating space, and the seal between the two is achieved by the O-ring between the two bonding surfaces. Flange joints can also be divided into three types according to the standard, which are metric square flange, imperial diamond flange, and U.S. SAE flange. American SAE flange with the same specification is also divided into light series (3000psi) and heavy series (6000psi) two. In addition to the four bolts used to fix the metric bolts and American bolts.
