Metal flat profile gasket with layers

revoseal Eco+

Eco+ consists of a solid stainless steel carrier covered on both sides with a narrow graphite or PTFE layer. A resilient “tooth” embossed towards the media side seals metallically on both flange faces. It absorbs changing forces caused by pressure and temperature fluctuations without plastic deformation.

160 bar

Pressure from vacuum to 160 bar (Class 900) · temperature −270 °C to +400 °C

Highlights

What sets Eco+ apart

Technical tightness

Exceeds TA Luft and VDI 2290 requirements in combination with a leakage verification according to EN 1591-1, even with lower-grade bolts.

No retightening

The resilient design makes retightening the bolts unnecessary, even with strong pressure and temperature fluctuations.

High surface pressure

The narrow soft-material layers achieve high surface pressures even at low bolt forces. Standard material 1.4571, total thickness 1.6 ± 0.1 mm.

Tested and certified

Fire-safe according to API 607, TA Luft including blow-out resistance according to VDI 2200, FDA conformity of the PTFE version.

Versions

Types and cross sections

Eco+

High-quality replacement for all flat gaskets up to 2 mm overall height in existing plants. In new designs, a cost-effective and technically better alternative to camprofile and spiral wound gaskets.

Eco PU

With PTFE U-jacket and diffusion barrier. Ideal for aggressive media in plastic or enamelled flanges.

Eco Top

Like Eco+, plus a secondary seal made of low-density graphite or PTFE. Reliably prevents corrosion of the flange sealing face, e.g. on carbon steel flanges.
