Kinking or twisting the hoses during installation shortens the hose life. Be sure to follow the proper procedure.

Tighten the fitting or nut to the torque value shown. Use one wrench to hold the body and one to tighten the nut.

For some hose fittings, the use of three wrenches is required to prevent twisting, one on the body, one on the nut, and one on the hose fitting.
