Floating Flange Rubber Expansion Loop: Easy-Install Flexible Pipe Coupler for Rapid Maintenance & Alignment
Product Description
Maximize your field efficiency with this floating flange rubber expansion loop, featuring loose, split-type flanges that rotate independently of the rubber body. This smart engineering feat means technicians can align bolt holes perfectly without twisting the rubber core, preventing catastrophic pre-installation torquing stress. It is the perfect maintenance component for rapid swap-outs in aging pipeline corridors where time is money.
Performance characteristics
1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced rubber compensator provides long-lasting performance.
3. Corrosion Resistance: Resists aggressive environments and
chemicals.
4. Noise & Vibration Reduction: Dampens vibrations and shock waves.
5. Ease of Installation & Maintenance: Compact design and standard
flange connections facilitate installation and upkeep.

FAQ
Q: Why do the metal flanges spin freely on the rubber body?
A: This is a floating flange design meant to simplify installation, allowing you to match any bolt pattern without twisting the elastomer.
Q: Do I need a heavy torque wrench to seal this joint?
A: No, standard cross-tightening with a regular wrench is enough, as the rubber flange face seals perfectly under normal torque.
