Made in America
|ProPull™ Lube, manufactured exclusively by PNA makes every long pull a smooth one. This cable lubricant provides complete non-separating disbursement in all types of duct; smooth, corrugated or ribbed. ProPull™ Lube is completely effective from 20° F to 250° F, will not harm duct or cable insulation and is environmentally safe.ProPull™ Lube will not evaporate, crystallize or deteriorate, and can be safely and effectively applied to cable being installed in a variety of duct materials, including fiberglass, PVC and steel.ProPull™ Lube can be applied during extrusion, pre-lubing the duct with 360° full coverage. ProPull™ Lube is also available in bulk sizes for field applications in 5 gallon pails or 1 gallon containers.ProPull™ Lube incorporates a long chain polymer gel, specifically developed for installation of cable in HDPE duct.
EASY TO USE
ProPull™ Lube is easily applied directly to the cable. However, on very long or difficult pulls, the use of a sponge spreader or lubricant applicator is desireable.
The surfactant used in ProPull™ Lube causes the lube to completely coat and cling to HDPE cable jackets and duct. This characteristic, in conjunction with the viscosity of the polymer gel, helps carry the lube completely through the duct.NON-DRYINGProPull™ Lube will not dry out on long pulls or under excessive heat conditions. The solids content of ProPull™ Lube is less than 0.6%. Other gel cable lubes can be as much as 5.0% solids. ProPull™ Lube contains virtually no solids and maintains stability to over 250° F.
ProPull™ Lube is non-toxic and non-hazardous to the environment. Its PH has been adjusted to neutral. The only danger is from lube spilled on non-absorbent surfaces. All spills should be covered or cleaned immediately. As with any industrial chemical, prolonged or repeated contact with eyes and skin should be avoided to prevent irritation. Eyes and skin should be flushed with water immediately after contact.
WILL NOT HARM CABLES
PNA’S ProPull™ Lube does not contain any silicone since there is evidence that silicone contributes to stress cracking of HDPE. Long period contact with highly plasticized materials such as polyvinyl chloride (PVC) should be avoided since silicone fluids leach out the plasticizer, causing shrinkage and hardening of the plastic.
ProPull™ Lube contains only cosmetic grade chemicals which have no effect on HDPE or other common cable sheath materials.

Quantity of ProPull™ Lube IN GALLONS
|Duct size(in inches)||500Feet||1,000Feet||2,000Feet||3,000Feet||4,000Feet||5,000Feet|
Where Q = Quanity in Gallons L = Length of Pull in Feet D = Inside Diameter of Duct
Q = .001 x L X D
NOTE: On very straight runs, half of the above recommended quantities may be sufficient. On very difficult pulls, twice the recommended amount may be required.
TEST: COEFFICIENT OF FRICTION
The coefficient of friction (COF) is dependent on the type of duct, rope, cable, cable jacket and type and quantity of lubricant. With a given COF, the layout of the duct becomes the biggest factor in pulling tension. Assuming a sample length of 200 feet, if the duct arcs only one foot every 30 feet, this represents 19° bend every 30 feet, or over 126° for 200 feet. A calculation error now becomes apparent, emphasizing the complexity in determining the contributing factors in even short pulling distances. ProPull™ Lube was tested during a power cable installation in a residential area: Severe conditions encountered in the 36-in -deep, 8-inch-wide trench included rocky soil, numerous driveway bores, a major road traffic load crossing and an approximate 25-foot incline with several duct routings. Other challenging aspects were multiple side-of-trench variations.
The power pole to transformer cable pull was 353 feet and exceeded 940° duct variations. Using 2-inch ID, pre-lubed PetroDuct™, and ProPull™ pulling rope which was pre-installed at the factory, the alum-2AWG STR cable was pulled without any external assistance at the rate of 50 feet per minute. Three gallons of ProPull™ Lube were used on the cable as it was pulled. In summary, the COF makes a major difference, as does the cable type, duct type and total degrees of bend in the duct layout.
