WaveGuard
Grooved gaskets taken to the next level
Up to 6 leakage classes better than conventional Grooved Gasket
Less emissions. Less corrosion. Less maintenance.
The WaveGuard combines the durability of classic grooved gaskets with significantly improved sealing performance.
At first glance, conventional grooved gsakets work reliably.
However, in daily use, typical weak points become apparent:
- Media losses due to higher leakage rates
- Contamination in the flange area
- Corrosion if the flange isn’t properly covered
- Damage to sensitive flange surfaces
- Time-consuming cleaning and limited reusability
These problems lead to higher maintenance costs, more downtime, and unnecessary emissions.

The Solution: WaveGuard
The next generation of grooved gaskets.
WaveGuard has been developed to retain the strengths of conventional grooved gaskets while specifically eliminating their weaknesses.
Its innovative wave-shaped geometry enhances sealing performance, protects the flange surface, and enables the metal core to be reused.
From two bathtubs down to a shot glass
The surface makes the difference
The sharp-edged surface of conventional grooved gaskets leads to:
- Damage to flange surfaces
- Limited reusability and recyclability
- Increased maintenance requirements and additional costs

The harmonized, wave-shaped surface of WaveGuard provides:
- Protection of flange surfaces and sealing faces
- High reusability and recyclability
- Reduced maintenance requirements and lower operating costs

Your Benefits
1. Significantly Lower Leakage
The optimized sealing surface improves leakage performance by up to six leakage classes at 30 MPa.
Your benefits:
- Reduced product losses
- Lower emissions
- Increased process reliability
2. Protection for your Flanges
The harmonized wave-shaped structure minimizes damage to flange surfaces.
Your benefits:
- Extended service life of flange connections
- Less rework during maintenance shutdowns
- Reduced risk of corrosion
3. Engineered for Demanding Applications
The solid metal core provides outstanding resistance to high pressure
and temperature loads.
Suitable for applications in:
- Chemical processing
- Power generation
- Process industries
- Plant and mechanical engineering
4. Sustainability Through Reusability
WaveGuard can be cleaned, inspected, and, if required, refaced with new sealing layers.
This means:
- Reduced material consumption
- Lower replacement part costs
- Reduced emissions
A Suitable Facing Material for Every Application
A range of facing materials is available to meet different operating conditions and process requirements.
| Material | Application |
| Graphite | Standard applications |
| Glimmer | Temperatures above 500 °C |
| Egraflex Steelflon | Residue-free removal |
