Polywater® Prelube 2000™ Cable Blowing Lubricant
Lubricant Increases Distance
When Blowing Fiber Optic Cable
Polywater® Prelube 2000™ reduces frictional drag during the blowing of outside plant fiber optic cable into duct. It increases the distance cable can be installed in a continuous length. Prelube 2000™ can also be used to blow in empty microducts for future microcable installation. Use Prelube 5000™ for blowing the microcables; see related products on the sidebar. For decades, Prelube 2000™ has been used to install hundreds of thousands cable on a wide range of cable blowing equipment.
When cable blowing, the cable stops moving when the frictional force resisting movement equals the blowing force producing movement. The maximum blowing distance varies linearly with friction coefficient in straight conduit sections. The friction reduction shown for Prelube 2000™ can increase installation distance by a factor of 5 or more versus unlubricated duct.

For smoothwall duct 1 – 1.25 in/2.5 – 3.0 cm inner diameter and piston type machines, use 5 to 10 fl. oz. per thousand feet of duct/0.5 to 1.0 liter per kilometer. Place 75% of the lubricant in front and 25% behind the missile. The lubricant is spread by the missile as the cable is blown.
The quantities of lubricant appropriate for any job will vary with the size, type and condition of the duct. Use the recommendations above as a place to start and adjust as necessary.
Polywater® Prelube 2000™ comes in two grades: regular grade (P) and winter grade (WP) for cold weather use in temperatures as low as -20°F/-30°C. The 1 quart/0.95 liter bottle is the most popular for field use. The long nozzle makes the injection of the lubricant easy.
