Farwest
Heat Shrinkable Anode Caps

Anode Caps for
Sealing Anode to Lead Wire Connections


Farwest Anode Caps seal and protect the
critical connection between the lead wire and anode. The tight fitting,
heat-shrinkable anode cap provides stress relief, moisture proofs and
electrically insulates the end of the anode at the lead wire exit point.
It is the ideal solution to the problem of premature system failure due to
loss of the wire due to anode termination.
A unique, highly stabilized polyolefin material is used to
mold the cap. During the manufacturing process, each cap is expanded to provide plenty of
clearance for easy installation over the lead wire and the anode. A rubber based sealant,
designed to adhere to anode materials and wire insulation, is uniformly coated on the
inside of the cap.
During installation, a propane torch is used to heat the
cap. As the temperature rises above 250oF, the sealant softens and the cap
shrinks tightly to conform to the anode and lead wire. When cooled, the cap and sealant
provide a durable and water tight encapsulation that will retain its flexibility and
integrity over a wide range of temperatures.
Anode Caps are designed for anodes from 1" to 4"
diameter. For high reliability in buried underwater cathodic protection systems, specify
Farwest Anode Caps.
