Indiana Seal is a company that has been manufacturing PVC pipe couplings in the United States since 1981. In 2007, we were purchased by GPK Products, an industry leader in rigid PVC fittings. We currently produce a full line of flexible pipe couplings in Fargo, North Dakota.
Our pipe couplings are able to connect a wide variety of pipe such as clay, cast iron, ductile iron, concrete, and PVC. We offer sizes ranging from 1 ¼ inches to 42 inches, and we are fully capable of producing custom pipe couplings of any dimension.
All of our couplings are made of tough and pliable PVC. This gives them the capability to withstand hazards such as sewer gases, chemicals, fungus growth, various soil conditions, roots, and other in-ground dangers that can lead to leaks and breakdowns in the system. We are AI certified, and throughout the manufacturing process, strict quality standards are expected and maintained from our in-house Quality Control department.
With our sights set to the future, we strive to be on the cutting edge of new products while producing the highest quality materials, offering the most exceptional customer service along the way.
