Need some help with a fitting indentification

[biggziff]

The fitting that screws into the valve body looks an O-ring boss style fitting. These can be either SAE American threads or metric ISO 6149. Ports styles are very similar

#6 SAE is 9/16-18 threads
#8 SAE is 3/4-16 threads

Metric sizes
M12x 1.5
M14x 1.5
M16x 1.5
M18 x 1.5

Threads into the valve body are British. Took the biggest truck/hydraulic shop in 50 miles nearly an hour to come up with something that fits. It's ugly, but it works...for now.

Glad you were able to get something that works.

British would point towards BSPP.
