Flexible coupling with flanges, L = 60mm, DN25KF, stainless steel 316L

Our Flexible Couplings are crafted from thin-wall hydroformed bellows, offering superior flexibility and stroke compared to standard bellows. With more convolutions, they deliver lower spring rates, making them ideal for alignment adjustments and vibration isolation—not for roughing lines.

🔧 Performance Highlights:

• Compression: Up to 20% of the flexible length
• Extension: Up to 10%
• Durability: Tested for 10,000 load cycles at 20 °C and 1013 mbar standard air pressure
• Also known as Metal Spring Bellows

🌡️ Temperature Range:

• From -196 °C to 300 °C (up to 350 °C for SS316)

📐 Specifications:

• Materials: SS304, SS316, SS316Ti
• Sizes: DN16 to DN50
• Length: 60mm to 150mm
• Stroke: ±6mm to ±21mm
• Pressure Rating: Down to 10⁻⁹ mbar

These couplings are perfect for high-precision vacuum systems where flexibility and vibration damping are critical.
