High-Quality, Quick Turnaround
Our flexible pipe couplings can connect to a wide variety of pipes, such as clay, cast iron, ductile iron, concrete, and PVC. We offer sizes ranging from 1 1/4 inches to 42 inches and are fully capable of producing custom couplings of any dimension.
All our couplings are made of tough and pliable PVC, which allows them to withstand hazards like sewer gases, chemicals, fungus growth, soil conditions, roots, and other inground dangers that can lead to leaks and breakdowns in the system. We are AI-certified and maintain strict quality standards under the surveillance of our in-house Quality Control Department. Our goal is to quickly and efficiently make products that are durable, high-quality, and accurate for whatever project you have planned.
