Techlube FO is a water-based lubricant for pulling fiber optic cables and inner ducts underground. It adheres well to cables in wet conditions and reduces friction during pulls. Techlube FO is non-toxic, non-flammable, and biodegradable. It can be used to lubricate plastic conduits for installing communication and fiber optic cables, as well as for inner duct installations and duct pre-lubrication. Formulas are provided to calculate the amount of Techlube FO needed based on conduit length and diameter.
