Abstract
A combination seal connects a filter or an equipment component to a base. The combination seal includes a seal material and flecks or particles made of intumescent material interspersed within the seal material. The flecks or particles of intumescent material undergo a chemical change when exposed to flames or heat and expand to maintain seal effectiveness and longevity without compromise.
