When You Don't Know the Fitting Name

Use when you are staring at a part and do not know what to call it.

What this covers

You need to ask for a fitting/tool/material but do not know the correct trade name.

How to use this playbook

  1. Describe function, shape, connection type, size, and where it goes.
  2. Say what shape it is: rectangular, round, spiral, oval, flex, transition, offset, elbow, tap, boot, collar, damper, access door.
  3. Say what it connects: duct-to-duct, duct-to-equipment, duct-to-diffuser, duct-to-wall/roof, branch-to-main.
  4. Say connection type: S-and-drive, TDC/Ductmate/flange, slip/coupler, flex collar, gasketed, welded, access door.
  5. Give dimensions and airflow direction if known.
  6. Take a photo and point at the specific edge/connection/part.
  7. Ask using function if you do not know the name.

Check

  • Whole fitting
  • Connection side
  • Size/tag
  • Where it needs to install

Warnings

  • Do not grab a random fitting because it looks close.
  • Do not call every connector a 'flange' or every round fitting a 'collar.'
  • Do not cut the wrong part to make it fit.
  • Do not be embarrassed - naming parts is a real apprentice skill.

Stop and ask

  • Ask when the part affects airflow, access, connection type, damper operation, grease/rated duct, or equipment connection.
