Hydraulic Fitting Torque Specifications
37 degree JIC, ORS, &ORB (REV. 10/97
This chart provides tightening torques for general purpose applications when special torques are not specified on
process or drawing. Assembly torques apply to plated nuts and capscrews assembled without supplemental
lubrication (as received condition). They do not apply if special graphite moly-disulfide or other extreme pressure
lubricants are used. When fasteners are dry (solvent cleaned) add 33% to as received condition torque. Bolt head
identification marks indicate grade and may vary from manufacturer to manufacturer. Thick nuts must be used on
grade 8 capscrews. Use value in [ ] if using prevailing torque nuts.

Before operating your Brillion machine, check all
hardware for tightness. Use the Tightening Torque Table
as a guide. See Page 4-1.
After a few hours of use, check entire machine and tighten
any loose nuts or bolts. Daily or periodic checks should be
made thereafter.
When replacing bolts, be sure to use fasteners of equal
grade.
