plugs are designed to organize and seal around single cables
and duct within larger casing pipe. This heavy duty design
provides an air and water tight seal, preventing the ingress
of external contaminants. Optimum pressures are achieved when
the simplex plugs are installed in conduit or a core hole
with an inside diameter that is closest to the net diameters
of the uncompressed rubber part of the seals. Hydrostatic
testing of this configuration will give a sustained hydrostatic
test pressure of 20 P.S.I..
multi-hole plugs are corrosion resistant with all plastic
and elastomeric construction and stainless steel fasteners.
