Aug. 21, 2020
Electri-Flex Liquatite conduit types LA, ZHLA, and CBLA are now CSA certified as “Heavy-Duty.”

Electri-Flex (Roselle, IL) announced that its Liquatite conduit product types LA, ZHLA, and CBLA now conform to C22.2 No. 56-17 Annex A “Heavy-Duty” for CSA certification.

The certification's “Heavy-Duty” annex requires liquidtight flexible metal conduit to pass additional tension, cold flexibility, connector compatibility, and crush tests.

The Heavy-Duty listing from CSA means that these conduit types passed vigorous testing, above and beyond standard CSA and UL 360 standards, across the following parameters, per the manufacturer:

  • Tension - Withstands greater tension force.
  • Tested to 500 lbs. which is a 66% greater force applied versus standard CSA and UL testing.
  • Cold Flexibility - Superior flexibility in cold temperatures.
  • Placed in a freezer for 4 hours, 300% longer cold exposure and then wrapped around a smaller mandrel with a 30-37% tighter bend radius.
  • Connector Compatibility - Stronger connector attachment.
  • Pulling force of 350 lbs., which is 133% greater force applied versus UL testing.
  • Crush - Excellent crush strength.
  • Meets the same tough standards as UL, 1,500 – 2,000 lbs. depending on conduit diameter.

Electri-Flex Liquatite products that meet CSA Annex A “Heavy-Duty” include Types LA, ZHLA, CBLA and CSA. Only conduit trade sizes ½” through 4” qualify for the (HD) “Heavy-Duty” designation.
