184 loading curve

184 loading curve Most compression With small amount Of load (S1) (.055) Very little creep Throughout test Almost no loss of Gasket thickness During loss of load

Glass filled PTFE gaskets

Glass filled PTFE gaskets Extreme amounts of Gasket creep at Higher gasket loads Major loss of Gasket thickness During loss of load

Virgin PTFE gaskets

Decay Curve of PTFE Gasketing Materials

Joint sealant family
high temperature service
pH 0 – 14
2000 psi (140 bar)
Fast, easy to use
Faster than cut rubber gaskets.
Cleaner and easier than two-part, spray can gaskets
Complete inventory of gasketing on a roll
Closed-cell foam forms and compresses better than solid silicone rubber
185
Superior sealability, even on worn or uneven flange surfaces
Long lasting, high reliability seal with minimum re-torque
Suitable for food grade applications

Case History – Brine pump
At a chemical plant in the Midwest the brine disposal pump had issues:
required re-packing twice per week
caused frequent gland leakage that sprayed brine towards the bearing housing
Brine solution contaminated the oil in the bearing housing, which caused premature bearing failures.
Over tightening caused shaft wear

Case History – Brine pump
Changed to Superset (SpiralTrac P version with 1730 packing)
Cut repacks to twice a year instead of twice a week
No more shaft wear
No more bearing failure
A 10X+ savings!!!
