Steel Straight Thread O-Ring

Assembly Instructions

Non-Adjustable Stud
  1. Inspect port area to be free of any contaminant.
  2. Lubricate o-ring and threads on fitting.
  3. Turn fitting into port finger tight, then torque to the value shown in the following tables.

Adjustable Stud
  1. Follow steps 1 and 2 from the foregoing instructions, then proceed to the following steps below.
  2. Looking at fitting from end with nut/washer/0-ring assembly, turn nut clockwise as far as possible.
  3. Using wrench pad, turn fitting into port until the washer touches the port spot face. Continue turning fitting until washer touches the thread nearest wrench pad.
  4. Back off fitting counterclockwise not exceeding one revolution until it is orientated in the correct position.
  5. Place wrench on the wrench pad of fitting to prevent fitting from turning, and torque nut to the value shown in the following table.

Why Wet Torque?

Due to the difference in plating types and thickness, materials, and thread quality of different components, the coefficient of friction varies greatly on any given assembly. Lubrication not only produces a more consistent coefficient of friction, it increases clamping force on sealing area with less torque on the threads. Overtightening causes threads to yield, deform and lose their ability to maintain an adequate load or clamping force on the seating area. Extended operation and severe conditions cause further yielding which results in leaks. Overtightening is the single greatest cause for leaks in metal to metal seat hydraulic connections. It is our firm position, that to not wet torque, is to compromise consistency and quality for convenience.
