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:
- 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.
ROC Carbon’s engineering staff is available to help you evaluate seal problems and to recommend solutions involving seal geometry and material.
