anode adaptor

To protect your tank or vessel from internal corrosion, the Internal Vessel Anode Adapter by Corrpro is the most cost-effective choice. The anode adapter can be mounted on most ANSI rated flanged access ports on your tank or vessel. Most commonly used with a 3” – 150lb or 4” – 150lb ANSI access fitting, the internal vessel anode adapter is also available in a wider variety of port sizes and pressure ratings. When partnered with a sacrificial anode, anode adapter lead and a corresponding insulating kit, the internal vessel anode adapter completes the cathodic protection circuit in your tank to provide a low maintenance and easily serviceable option to mitigate internal corrosion.

  • Designed to work with most ANSI rated flanged access ports
  • 5/8” NF threading on the barrel to support most sacrificial anode sizes
  • Coated with Endura EX-2C for high resistance to chemicals, abrasions and impact
  • Custom sizes and coatings available upon request.

Designed with sizes to fit into the majority of flanged access ports on a tank or vessel.  The Internal Vessel Anode Adapter bolts onto most ANSI rated flange access ports and can hold several sacrificial anodes (when supported internally). The anode adapter works with 3"x22" and 3"x30" Aluminum, Magnesium and Zinc anodes with a 5/8" N.F. threading. If multiple anodes are installed onto one adapter a support arm will be required.


Corrpro supplies a full line of Internal Vessel Anode Adapters to meet your tanks criteria. To order the required adapter, indicate the size of the port you are installing on to, if you require an insulating kit, adapter lead, anode materials and support mechanism.

Standard sizes are 3" - 150lb and 4" - 150lb with Endura Blue coating. Custom sized adapters and custom coating requirements can be manufactured upon request.
