Watts Bolt Insulator Kits - Manual

Description
Series 3000 Dielectric Pipe
Fittings and Unions are
durable, corrosion resistant
fittings and unions that con-
sist of a union nut and two
tailpieces. A gasket sepa-
rates the two tailpieces pre-
venting an electric current
from passing. For flanged
fittings (Models 3100, 3110,
and 3200), a bolt insulator is
required to insulate each
bolt in the flange. Watts
also offers bolt insulators in
a range of sizes.
Dielectric fittings/unions
are designed to install
between pipes made from dissimilar metals. They pre-
vent accelerated corrosion and deterioration in the
piping system due to galvanic and stray current.
Features
• Designed and manufactured to the highest
quality standards.
• Unions individually factory certified to withstand a
minimum of 600 volts on a dry line with no
flashover.
• Unions rated to 180°F (82°C) at 250psi (17.2 bar).
• Flanged fittings rated at 175psi (12.1 bar).
• Standard Gasket A (GA) suitable for water, air, oil,
natural gas, propane, gasoline, kerosene, mineral oil,
vegetable oil, and alkalines in 180°F (82°C) at 250psi.
Applications
Dielectric fittings/unions are for use in residential, com-
mercial, and industrial applications. Specific applica-
tions include the connections of piping of dissimilar
metals on hot water storage tanks, water and air con-
ditioners, processing tanks,
steam, gas, and water pip-
ing. These fittings/unions
prevent the flow of galvanic
current (an electric current)
and stray current (DC cur-
rent) passing from one dis-
similar metal to another.
Galvanic current accelerates
corrosion in the piping sys-
tem leading to premature
deterioration of the system.
Stray current produces
extraordinary anodes and
cathodes that can inadver-
tently enter an alternate (but
unintended) path and create
corrosion in the piping sys-
tem. Using dielectric fit-
tings/unions prevents this
type of corrosion from occurring.
Note: For applications of gaskets other than specified
above, contact your local authorized Watts representa-
tive.
