Blue Diamond Industries is a premier manufacturer of High Density Polyethylene (HDPE) conduit headquartered in Lexington, KY. In the spring of 2020, BDI opened its second manufacturing facility in Aubrey, TX, boasting high efficiency, top of the line machines. This facility will allow us to better serve our customers in the Western Market. Our facility in Middlesboro, KY has been manufacturing conduit for more than 15 years.

Blue Diamond manufactures sizes in ½” through 6” and meets all standard specifications such as ASTM, UL and NEMA. BDI offers a wide range of microduct sizes and configurations in single and multi-tube along with hybrid combinations. Our Quality Management Program is ISO 9001:2015 certified.



Blue Diamond offers a wide range of products in sizes 1/2″ through 6″ in a variety of colors and striping combinations. Other options include pre-lubrication, pre-installed pull tape, pre-installed cable in conduit and a toneable wire. Blue Diamond complies with RUS/USDA standards, meets Buy America Requirements and all national specifications including ASTM, NEMA and UL.

Blue Diamond offers both single tube and multi-tube combinations. Whether microtrenching, installing Fiber to the Home, 5G wireless, or highspeed business campuses, microducts from Blue Diamond can be the right solution. Our multi-tube duct is offered in both regular wall and heavy wall oversheath options. Other standard features include ribbed inside wall, and a permanent SuperGlide® interior.

Blue Diamond has developed a “Boreable” HDPE continuous conduit with 3 or 4 innerducts pre-installed. The innerducts are installed at our manufacturing facility during the extrusion process. Blue Diamond 3N1™ saves time and money as the innerducts do not have to be pulled through after the bore, allowing you to blow fiber or pull power cables as soon as the bore is complete.
