Product Description

Product Overview

The DN32 Single Sphere Rubber Expansion Joint is a compact and highly flexible connector designed to absorb vibration, compensate for thermal expansion, and reduce pipeline noise.
Manufactured according to ANSI 150LB flange standard, this model is made with high-quality EPDM rubber and galvanized carbon steel flanges, ensuring excellent durability and corrosion resistance in various industrial environments.

This small-diameter (DN32, 1¼ inch) expansion joint is widely used in water supply systems, HVAC pipelines, pump connections, and industrial fluid transportation where flexibility and leak-proof performance are essential.
