As a trusted gasket material supplier, our recommendation is that you never reuse a gasket. And maybe…there is a time or two that it really might be ok to reuse one. There are many people out there that would never replace a gasket. How does one really know if it is going to work the same way twice? Here are some of the common arguments for never reusing a gasket.
Exposure to elevated temperatures causes materials to deteriorate. Sometimes this means: dry out, stiffen up, saturate, get brittle, take a set, etc. A new gasket is required to go through the initial seating phase and achieve a proper seal. Exposure to fluids sometimes causes materials to swell, impregnate, or saturate.
In a seal situation, this often helps to create the seal. Reusing a gasket is not advised as the saturation and absorbancy condition can vary. A gasket should be assembled, then exposed to heat and fluid. A used gasket already having swelling due to the fluids should not be reused. The third reason not to reuse a gasket is related to the first two.
Once a gasket has taken a set due to temperature and fluids , it should not be disturbed or reused. It would not have the same properties available to go through the initial compression provided by the joint and achieve the initial seal.
We know for a fact that our material can handle the conditions it is specified for IF the gasket and joint is designed properly, and installed correctly. Replace to be safe!

Do metal gaskets need sealant? Also, RTV can extrude out when the gasket is compressed, and it could end up in an oil or coolant passage and restrict or block flow. If a carrier-style gasket requires a sealant, some will include a portion in the kit. Do paper gaskets need sealant? I put a skim coat of RTV on them. I've never used sealant on paper gaskets.
