JIS Port Data

[rock]

I'm looking to purchase a JIS Standards Handbook for with Hydraulic Port Data in it. In particular, I'm currently looking for port and fittting data on the JIS B2351 Port. It's found on a lot of Japanese produced excavators. Wierdly, it employs a BSPP Thread. Where do they come up with this stuff? Can anyone tell me where to<br>
order such a handbook?<br>
<br>
Thanks in advance,<br>
Rock.
