💡 Pro Tip from Our Engineers:

"For permanent installations, apply a thin layer of silicone grease before insertion. This creates a superior seal while still allowing removal if needed. Always measure your hole diameter precisely - these plugs work best with 0.5mm tolerance."

"I've used these in my HVAC business for 3 years - outlast metal caps in extreme temperatures!" - Mark T., Professional Contractor
