PVC Coated Conduit System

KorKap PVC Coated Conduit System

KorKap offers a complete line of PVC coated conduit, fittings and accessories to provide resistance to corrosion for your electrical raceway systems in the most demanding environments.

Manufactured in the U.S.A., ISO 9001-certified KorKap complies with all standards mandated by UL6, NEMA RN-1, ANSI C80.1 and ETL PVC-001. KorKap is ETL-Verified for product performance and reliable longevity — ETL-Verified PVC coated conduit provides product service life lasting 10 times longer than those who do not carry the ETL PVC-001 label.

Additional features include our V-Seal® gasket with special interlocking “V” groove which is the most effective way of preventing corrosion damage by sealing PVC coated Form 8 Conduit Bodies.

KorKap is not simply a product — it is a key link in a system designed to beat the high cost of corrosion damage. The following graphic illustrates how the beneficial differentiators of KorKap provide added value in making the system work.


Our Unique V-Seal

Our V-Seal® gasket — with special interlocking “V” groove —- is the most effective way of preventing corrosion damage by sealing PVC coated Form 8 Conduit Bodies, sizes 1/2″ to 2″.


KorKap complies with standards including:

  • NEMA RN-1
  • ANSI C80.1
  • UL 6
  • ETL PVC-001

UL6 is an important standard that addresses safety for rigid metal conduit. ETL PVC-001 is an internationally recognized listing based on performance evaluations and on predicting service life. It is on the basis of independent, objective product comparisons by ETL that KorKap has been proven to provide ten or more times the protective service life of brands that are not authorized to carry the ETL PVC-001 label.


Here are some additional facts that you should know:

  • ETL PVC-001 validates the coating performance of PVC-coated galvanized rigid conduit based on ASTM D870 and ASTM D1151/ASTM D2247 — the accepted ASTM tests for predicting product service life. These tests are not intended to replicate a specific environment. Rather, they are designed to predict the service life of a coating under the two most common conditions that affect adhesive bonds: heat and humidity.
  • KorKap re-earns its ETL PVC-001 label on a quarterly basis by repeatedly and successfully passing the stringent performance tests required for verification.
    • ETL verification is an “open standard”. Testing is open to any manufacturer who believes that the quality of its protective coating can consistently meet ETL verification requirements. If you do not see an ETL label on a brand of PVC-coated galvanized rigid conduit, you have every right to ask “why not?”

Training and Certification

KorKap offers various educational training opportunities such as:
