Fins (Gusset Plates) for Small-Bore Attachments

Gusset plates to absorb excessive vibrations

DamperX™ fins are custom-cut pieces of specialized viscoelastic material used to dampen out excessive vibrations on small-bore attachments. The fins (or gussets) are glued into place using a structural adhesive. In many cases, installation can happen in 20 minutes. The fins can also be painted for a consistent finish.



  • DamperX fins damping gussets on small-bore connectionNo welding
  • Fast installation
  • Long-lasting (track record of 5+ years of service)
  • Custom-cut to your application
  • Easy to implement
  • Effectively solve small-bore vibration problems

DamperX™ fins are best suited for small-bore connections that can be supported back to either the main pipe or nearby structure within a length of about 6 inches (150mm) or less.


  • Operating temperature range of -17⁰C to +60⁰C (1⁰F to 140⁰F)
  • Branch connection sizes 20mm to 200mm (¾” to 8”)
  • Installation and curing while shut down

Where to use DamperX fins

  • Flexibility in the nozzle or shell
  • Resonant vibration
  • Geometry

When not to use DamperX fins

  • During the design phase, in place of a bad design
  • Vibration limits after fin install
  • Geometry restrictions
How it works

DamperX fins damping gussets on vesselWe provide custom-cut DamperX fins shipped directly to site, based on photos and some basic dimensions of your small-bore attachment.

  1. Send us an email, including:
    • Photos of the small-bore connection from several directions
    • Directions the vibration is occurring
    • Some basic dimensions and a sketch (if needed) using the small-bore connection dimensions form (attach a photo or scan of the filled in dimensions form to the email)
  2. We quote a price, and you can pay quickly via credit card or purchase order
  3. Our technicians custom-cut your fins to size and ship them to site within two days (some custom applications may require more time)
