Features

Designed to absorb vibration and compensate small movements, improving piping reliability in compact threaded installations.

✅Vibration & Noise Isolation: Rubber body dampens pump and equipment vibration, helping protect valves, meters, and piping supports.

✅Movement Compensation: Supports compensation of minor axial/lateral/angle movements to reduce stress from thermal expansion and installation misalignment.

✅Union Threaded Ends: Union-style threaded connections enable quick installation, removal, and replacement with minimal downtime.

✅Material Options for Media: Rubber compound and metal end materials can be selected for water, mild chemicals, and other service conditions.

✅Compact Retrofit Solution: Ideal for tight spaces and retrofit projects where flanged joints are inconvenient.
