Overview

A hose kit containing various sizes of silicone tubing used to connect pressure switches to the inducer motor port. Over time, these hoses can crack, harden, or develop pinhole leaks that cause intermittent pressure switch faults. This kit gives you the most common sizes in one package so you have the right hose when you need it.

Pros

  • Multiple hose sizes in one kit covers most furnace applications
  • Silicone material resists heat better than standard rubber tubing
  • Simple replacement — cut to length and push on
  • Inexpensive insurance against intermittent pressure switch faults

Cons

  • Hose diameter may not match every furnace brand
  • Silicone can still harden over time in high-heat applications
  • Some kits include sizes you'll never use

Who It's For

DIY homeowners troubleshooting intermittent pressure switch codes. If your furnace occasionally throws a pressure switch error but tests ok at service, the hose may have a hairline crack. $12 and 5 minutes to rule this out.

Who Should Skip This

If your pressure switch hose looks fine and there's no evidence of cracking, the switch itself or the vent is the more likely problem.

Compatibility

Most residential gas furnaces with silicone pressure switch tubing

Bottom Line

A cheap and fast diagnostic step. If you're getting intermittent pressure switch errors and the hose looks original, replace it. It either fixes the problem or rules out the simplest cause.
