Gasket Compression-Torque requirement per gasket type
Gasket Compression-Torque requirement per gasket type
(OP)
I am looking for compression requirements for gaskets. The types are spiral-wound, neoprene, soft iron, EPDM, and flexible graphite. Any suggestions where to look?

Minimum seating stress values I use are as follows:
Flexible graphite filler, pipe flange spiral wound
= 10,000psi
Same, with inner ring = 15,000 psi
Elastomers = 500 psi (1,500 psi max)
Flexible graphite sheet gaskets = 5,000 psi (15,000 psi max)
Soft iron = 20,000 psi
Be careful not to exceed the maximum stresses on elastomers and flexible graphite sheet gaskets.

Always use the grade of bolt specified by design. Just because soft gasket seating stresses are lower for some gaskets don’t downgrade your fasteners. Always use the correct bolt tightening procedures. Taking a little care will prevent a lot of leaks.

Do you have max values for the different type gaskets?
