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.
Key Features
High-Performance EPDM Rubber:
Resistant to aging, ozone, acid, alkali, and high temperatures up to 120 °C, ensuring long service life.
ANSI 150LB Standard Flanges:
Precisely machined and hot-dip galvanized for excellent corrosion resistance.
Compact Single-Sphere Design:
Allows greater flexibility and movement absorption in a smaller space.
Effective Vibration & Noise Reduction:
Ideal for pumps, chillers, compressors, and pipelines requiring stability and low vibration.
Easy Installation & Maintenance:
Lightweight, detachable, and compatible with both steel and PVC pipe systems.
