ROC

Labyrinth Seals

ROC manufactures labyrinth seals up to 12 inches OD for all makes and models of turbines. Our CNC machining capabilites include the full range of tooth configurations: straight, stepped, angled, staggered, and more. We work from customer-furnished drawings or samples. Custom sizes and fast delivery are our specialty.

These seals (typically two-piece) are precision-machined at our Houston facility. To match virtually any application, we offer the following materials:

  • bronze
  • aluminum
  • nickel-silver alloy
  • as well as other materials upon request

The seals are machined with no gap at the split line and ID tolerance as tight as ± 0.001 in for maximum sealing effectiveness.
