HDPE fittings: industry-best selection and capabilities.

Molded fittings are known for their reliable quality, wall thickness and integral reinforcement, that withstand stress. ISCO offers a full line of pressure-rated HDPE butt fusion fittings, molded and reinforced at the bend, branch or reduction point for optimum strength and long-term performance.

Fabricated fittings are used when standard options won’t work, such as large-diameter pipes or unique angles. ISCO’s expert fabrication team designs and fabricates custom HDPE fittings in virtually any size or configuration to meet your needs. Fabricated fittings include elbows, flanges, reducers, tees and other custom shapes. Fabricated fittings can be more economical than creating molds for standard fittings.

Fittings for fire protection systems that meet FM Global’s rigorous criteria, ensuring they can withstand extreme conditions and perform reliably

Electrofusion fittings are widely used in gas and water distribution systems, industrial piping networks and other applications where reliable leak-proof connections are needed. ISCO molds its electrofusion fittings from virgin, PPI-listed resin for maximum leak resistance — designed to meet or exceed ASTM standards.

Specialty fittings are custom components used in piping systems that have been designed for specific functions or environments. ISCO offers specialty fitting solutions backed by over 40 years of industry experience — part of our one-stop capabilities for even the most demanding pipe applications.
