About Us


Experience counts...

Power Lube Industrial, formerly known as PLI, LLC, is a company with over 42 years of experience in the self-contained automatic lubricator field.

It is the oldest surviving company in the U.S. that began its existence as a marketer of this new lubrication technology. It also has the distinction of having been founded by a woman, who, as its president and only employee, began successfully selling this new technology to industrial accounts.

Over the years, evolution of the company and the technology saw the name of the organization change from Perma Distributors, Inc., to Perma Inc. Then, with the change of product being marketed to the newer, more versatile Electro-LubeĀ® Lubricator, the company became PLI, LLC.

Our new company name, Power Lube Industrial, LLC, is a reflection of the continued growth of this family-owned business to include third generation family members, as well as the continued expansion of the line of selective, cost saving industrial lubrication products.

We are proud to have had you, our customers, share in this challenging, interesting and rewarding journey in an American free enterprise experience. We look forward to continuing to serve you for many years into the future.

Our seasonedĀ  personnel will do their absolute best to provide you with the most cost effective and reliable solution to your lubrication requirements. Please call us at any time to discuss your application requirements. There is, of course, no obligation on your part - - it's what we do.
