Calbond® Product Specifications

  1. The conduit shall be hot-dipped galvanized inside and out with galvanized threads.
  2. The PVC coated conduit must be listed by UL with both the Zinc Coating and the PVC Coating Each serving as PRIMARY COATINGS by itself under UL-6.
  3. The PVC Coating on the Conduit shall conform in ALL RESPECTS to the NEMA RN-1 Standard.
  4. All fittings shall be UL listed prior to coating.
  5. All Fittings shall be supplied with Stainless Steel Screws equipped with PVC Encapsulated heads.
  6. All Conduit and Fittings shall have a 2 mil (.020”) thick Urethane coating on their interior surfaces. The bond of the interior coating shall be tested using the Tape Test method (ASTM D3359) and will show no trace of paint after an Acetone wipe using test method (ASTM D1308).
  7. All Male threads of Elbows, Nipples and factory offsets will be Galvanized.
  8. All Female threads will be protected by a Urethane coating.
  9. All Female threads will have a PVC flexible sleeve extending from them to facilitate complete coverage of the installed conduit. The length of the sleeve will be one pipe diameter but no more than 2”.
  10. All Conduit Clamps will be oversized to fit the PVC Coated Conduit or will be made of Stainless Steel.
