The SAE Handbook covers the JIC Hydraulic Tube Fittings in all aspects including torque values. The standard is<br>
SAE J514. The Handbook can be ordered from SAE's site (sae.org) It's an invaluable tool) If your not into ordering it, your local supplier of hose assemblies and adaptors should be able to supply the basic information. <br>
Hope this helps.<br>
