Wide Range Adapter – Model 4428
Product Overview
The Model 4428 Wide Range Adapter is a versatile mechanical coupling solution designed to connect 2"–24" PVC pipes with secure, leak-free performance. Engineered for waterworks, wastewater, and industrial piping systems, this adapter accommodates a wide diameter range, reducing the need for multiple coupling sizes and simplifying inventory management.
Built from high-strength ductile iron (ASTM A536, Grade 65-45-12) and coated inside and out with fusion bonded epoxy (AWWA C550), the Wide Range Adapter ensures long-lasting corrosion resistance and durability. The design includes an EPDM gasket and stainless steel bolts, providing a watertight seal and reliable joint performance under working pressures up to 250 PSI.
