Shielding
Express Knit Shield Ring gaskets and
contact buttons are
constructed by die-compressing knitted wire
mesh in forms. They can be made in a wide
variety of shapes and sizes, with
varied density and with controlled
resiliency. The gaskets are generally held
in place by sidewall friction in slots or
grooves machined into the mating surface(s)
to be gasketed.
Depending on gasket width and material they
may be designed to accommodate bolt holes.
