Special gasket
revoseal JG/JP
Encapsulated flat profile gasket: the internationally patented geometry of the raised outer and inner teeth completely encapsulates the graphite or PTFE layer. The tooth geometry is calculated so that ideal compression of the graphite and a double metallic seal are achieved even with low-grade bolts. revoseal JG and JP combine the advantages of metallic and soft-material sealing in an ideal way.
400 bar
Pressure from vacuum to 400 bar (Class 1500) · temperature −270 °C to +1000 °C, depending on the carrier material
Highlights
What sets JG/JP apart
Verifiable technical tightness
For apparatus flanges, the effective gasket width can be adapted for the qualified calculation of technical tightness according to TA Luft and VDI 2290 per DIN EN 1591-1.
Extreme operating ranges
Temperature: −270 °C to +1000 °C (depending on the carrier material). Pressure: from vacuum to 400 bar (Class 1500).
Lowest leakage rates
Lowest leakage rates of all gaskets available on the market. The JG/JP profiles build the tongue-and-groove principle into the gasket.
Tested and certified
Fire-safe certificate according to API 607 (also for PTFE) and blow-out resistance according to VDI 2200. Standard material 1.4571, total thickness 4.2 mm – other materials and thicknesses on request.
Versions
Types and cross sections

Apparatus & special gaskets
Custom-made to your specifications
Gasket solutions for apparatus and special flanges
For apparatus and special flanges, revoseal also manufactures high-quality gasket solutions to customer specifications with precise dimensions – for example gaskets for heat exchangers, pressure vessels, tank and filter systems, and for equipment and plants in the following sectors:
- Chemical and petrochemical industry
- Pipeline construction (oil and gas)
- Refineries
- Power plant construction
- Industrial plants
- Food and pharmaceutical industry
Due to their design, apparatus such as heat exchangers often have thin walls and weak flange geometries, which makes finding the optimal gasket a challenge. For apparatus flanges, the effective gasket width can be adapted for the qualified calculation of technical tightness according to TA Luft and VDI 2290 per DIN EN 1591-1. Gasket dimensions up to 4,000 mm are possible.
