GARLOCK GRAPH-LOCK

GRAPH-LOCK is composed of pure, exfoliated flake material. It excels in extreme conditions and withstands high temperatures, high pressures, and aggressive chemicals. It also provides excellent resistance and is proven to be fire-safe.

GRAPH-LOCK gasketing provides a reliable seal as it seals easily under moderate bolt load, offers superior torque retention, retains dimensional stability in high temperatures and seals tightly, even during pressure fluctuations. Flexible graphite is manufactured in such a manner that no organic or inorganic binders and fillers are introduced — the end product is essentially pure graphite with outstanding physical properties. The insertion of wire mesh, stainless steel foil, and tanged metal inserts increase strength and ease of handling.

GRAPH-LOCK gasketing is available in two grades: industrial grade, which is 98% pure, and nuclear grade, which is 99.5% pure. It is available as standard homogeneous sheet or metal- inserted sheet for applications requiring extra strength.

Gasket Supply carries a wide variety of Garlock’s GRAPH-LOCK materials. We can CNC cut and waterjet cut gaskets to meet your exact requirements.

 

AVAILABLE GYLON GRAPH-LOCK MATERIALS

 

GRAPH-LOCK 3123 / 3125 FLEXIBLE GRAPHITE GASKETING

The graphite flake has been acid washed, expanded under heat, and then compressed into sheets with a minimum graphite content of 98%. For thicknesses under 1/16” homogenous graphite is used. For thicknesses over 1/16” laminated graphite is used. The laminated graphite sheets are bonded with a proprietary adhesive. This adhesive makes up less than 1% of the total laminated weight. 

This material has an excellent resistance and is proven fire-safe and reliable. It seals easily under moderate bolt load and offers superior torque retention. It retains its dimensional stability in high temperatures and seals tightly even during pressure fluctuations.

 

GRAPH-LOCK 3124 / 3126 FLEXIBLE GRAPHITE GASKETING

GRAPH-LOCK 3124 and 3126 feature laminated layers of purified natural graphite flake that have been acid washed, expanded under heat, and then compressed into sheets with a minimum graphite content of 98%. This sheet contains a 0.0075” thick – JC thick 316 stainless steel wire mesh (24 mesh) insert, bonded with a proprietary adhesive. This adhesive makes up less than 1% of the total laminated weight. 

This material has an excellent resistance and is proven fire-safe and reliable. It is a pure exfoliated graphite flake material excels in extreme conditions, withstanding heat, pressure, and aggressive chemicals. It seals easily under moderate bolt load and offers superior torque retention. It retains its dimensional stability in high temperatures and seals tightly even during pressure fluctuations.

 

GRAPH-LOCK 3125SS FLEXIBLE GRAPHITE GASKETING

GRAPH-LOCK 3125SS has laminated layers of 0.015″ purified natural graphite flake that have been acid washed, expanded under heat and then compressed into sheets with a minimum graphite content of 98%.
