 Our
Ultem tube plugs are made with Ultem nut and bolt assembly.
Ultem is a fiberglass reinforced resin. We manufacture the
collar and washers are made from a non-water soluble hard
plastic called Hytrel™ and the silicone parts are of
a vulcanized silicone rubber.
There are no metal parts to this tube plug, eliminating
the concern of any galvanic action inside the tubes which
can lead to pitting and premature deterioration of the tubes.
These plugs are offered in either a double size (two silicone
parts) or a single size (one silicone part). The single
plugs are recommended for lower pressures and the doubles
are for pressures between 60 psi and 150 psi.
