DIAMOND-COATING SEAL FACE TECHNOLOGY
FlexICE™ Diamond Face Technology for Mechanical Seals
Solve chronic seal failures while cutting cooling water and power use
FlexICE™ is Flexaseal’s advanced diamond-bond coating engineered to dramatically extend the life and performance of your most challenging mechanical seal applications. Applied to silicon or tungsten carbide seal faces, FlexICE™ delivers exceptional hardness, ultra-low friction, and superior thermal conductivity, allowing seals to handle dry running, frequent stop/starts, and low-lubricity fluids where traditional materials fail. The result: higher reliability, longer MTBR, and reduced total cost of ownership across some of your toughest applications.
WHY USE FLEXICE™
- Intermittent dry running and frequent stop/starts are tolerated, when otherwise temperatures would spike, causing elastomer failures, face blistering and leaks.
- Low-lubricity fluids like hot water, condensate, and light hydrocarbons can be sealed because FlexICE™ coated faces are less reliant on a stable fluid film for support.
- Ultra-high face hardness prevents damage from solids and abrasives.
- Lower friction and cooling water demands reduce costs of auxiliary support.

APPLY FLEXICE™ FOR MANY OPERATIONAL CHALLENGES
FlexICE™ technology on mechanical seal faces directly addresses the operational weaknesses that cause many seal failures. By creating an ultra-hard, low-friction, thermally conductive barrier, FlexICE™ faces:
- Tolerate intermittent dry-running during start-up, shutdown, or upset.
- Perform reliably in low-lubricity fluids such as hot condensate, light hydrocarbons, and fluids with entrained gas.
- Resist abrasive wear from slurries, fibers, or particulates, maintaining flatness and seal integrity.
- Run cooler and more efficiently, reducing auxiliary cooling demand and energy losses.
The result is often a significant increase in Mean Time Between Repair (MTBR), particularly in bad-actor applications where conventional seals routinely fail.
