Gasket self-loads in oil or water
Gaskets sometimes fail if there is not enough load on them to maintain a seal, but this product actually increases its own gasket load when it comes into contact with oil or water.
Multi-Swell gasketing material, intoduced by Garlock Sealing Technologies is claimed to be the first self-loading general service gasket It develops its own load when in contact with oil or water

Multi-Swell virtually eliminates the most common cause of gasket failure - insufficient load.
Garlock Sealing Technologies said that the material performs equally well in oil or water and does not degrade in contact with oils.
It also adapts easily to all types of flange designs and its cost is comparable with conventional gasket materials.

"More than 70% of all gasket failures are due to lack of load," said Tim Hurley, Garlock product manager.
"Multi-Swell generates and maintains its own load.
It works well even in combination with flanges in poor condition or flanges designed for soft, low performance gaskets".
Twice as soft as conventional gaskets, Multi-Swell is easy to cut and readily conformable even to irregular flanges, ensuring tight seals with lower loads.
Multi-Swell has extremely high crush strength and can be safely installed in applications that would typically crush elastomeric gaskets.
In applications such as transmissions and air conditioning systems, where vibration often causes bolt load loss or where load loss occurs because of bolt relaxation, Multi-Swell counters that loss to prevent leakage and weeping.
Because it performs well under low load conditions, Multi-Swell can be used with confidence, said Garlock Sealing Technologies, even with plastics or cast iron flanges.
Using Multi-Swell reduces the expenses associated with vegetable fiber and cork gaskets.
Cork and vegetable fiber gaskets' capillary leak paths require the use of absorbent oil pads, create oil loss and safety issues, and sometimes necessitate expensive water treatment when leakage occurs.
The use of Multi-Swell eliminates these costs and environmental risks.
Multi-Swell can be used in compressors, pumps, gear boxes, transformers, fuel pumps and cast water flanges.
