Where to buy

TIFCO sells online with an account and cart. You can also order by phone at 800-868-4326.

Marketplaces rarely list TIFCO parts. Use the part number to match an equal connector from another brand.

Professional insight

Electricians choose by conductor count and gauge range first. Brand comes second.

  • Count every conductor, including the pigtail, before choosing.
  • Check whether stranded wire is approved for push in ports.
  • Match the listed voltage rating to the circuit.
  • Order by part number to keep color codes consistent.
