Flange Isolation with excellent characteristics

The GLV-UniSeal® T and the GLVUniSeal ® GGr are high quality isolating gaskets. With the surfaces of the seal retainer closed on all sides. water absorption is reduced to an absolute minimum.

General use:

Flange isolation gaskets combined with isolating sleeves and washers satisfy the requirements of cathodic protection.

Flange isolation kits can be used in chemically aggressive environments for sealing flammable gases and liquids.

The GLV flange isolation kits can also be used for general sealing purposes .

 The GLV-UniSeal® T and GLV-UniSeal® GGr make use of indirect bolt force load, which means that the gasket can be used wherever an absolutely tight sealing must be achieved with low surface pressure. The silicone or graphite ring is permanently elastic throughout the entire lifetime of the seal and is does not age or become brittle due to the temperature or media it is subjected. The O-ring properties of the silicone or graphite ring guarantee optimal sealing under indirect bolt force load. .

Generally the gasket can be used on all DIN or ANSI flanges. It can be installed in new systems or replaced during maintenance work.

Advantages of GLV-UniSeal®T and GGR Seals at a glance

• Easy to install
• Maintenance-free, as no retightening of the bolts required
• Blow-out safety due to chambered sealing rings inside grooves 
• Permanently elastic due to being a pure graphite seal (does not
  become brittle due to temperature)
• Suitable for heavy duty service due to indirect bolt force load 
• Functionally reliable due to lowest water absorption
