How much does a Garlock gasket compress?

Garlock recommends a maximum compressive stress of 15,000 psi on compressed fiber and GYLON® gasketing, and 10,000 psi on GRAPH-LOCK® and MULTI-SWELL gasketing. The actual crush strength of these materials is typically higher.

What is Garlock Packing?

Garlock Compression Packing is rigorously tested to ensure effective sealing in valves, pumps, agitators, and other rotary equipment.

What is aramid fiber gasket?

The unique blend of aramid fibers, fillers and elastomeric binders provides improved torque retention and drastically lowered emissions levels. Aramid fibers are a class of heat-resistant and strong synthetic fibers.

How much asbestos is in a gasket?

Sheet gasket material commonly contained up to 70% to 80% chrysotile asbestos. Gaskets designed for acidic environments often contained a more dangerous form of asbestos called crocidolite, which is also known as blue asbestos. The fiber filler in spiral wound gaskets was often almost completely pure asbestos.

What is PTFE gland packing?

PTFE Gland Packing PTFE Packing Style 3000T is a general purpose type of gland packing able to be used to seal in pumps and valves. Made with a PTFE lubricant it is tough, long lasting and very low friction. It is available by the metre.

How do I choose a gasket hardness?

As a general rule, a rubber gasket should be soft enough to fill and seal the gap between two surfaces, but at the same time needs to be hard enough to resist loading forces and not be extruded out of the joint. Hardness of a gasket elastomer is typically measured by the Shore A scale.

Which gasket is used for high temperature?

Silicone, fluorocarbon, and fluorosilicone and EPDM are considered high temperature rubber materials and are readily available in sheet stock form (solid silicone sheet, closed cell sponge, and open cell foam).
