Manhole and Handhole Gaskets (HH GASKET 4-1/2X3X1/2X1/4)
HH GASKET 4-1/2X3X1/2X1/4|Sepco’s gaskets are made of wire-inserted commercial grade cloth, then treated with a high heat-resisting rubber compound, folded, then formed to the required size and shape. They are recommended for use on boiler manhole and handhole covers, where conditions require a soft, compressible gasket against temperatures up to 450°F.
