Oatey 33927 Plastic Pipe Strap — 3/4" × 100 ft Roll, Polyethylene

The polyethylene hanger strap that doesn't transmit fan vibration to the house

Steel plumber's tape passes radon-fan vibration straight into the framing it's nailed to — you can feel it on a quiet night and hear it through finished ceilings months later. Oatey 33927 plastic strap solves that. Flexible polyethylene damps the vibration before it reaches your joists, dramatically reducing structural noise transmission.

Why mitigators prefer it over steel tape

• Vibration isolation — polyethylene damps the harmonic the fan generates; steel tape doesn't
• Non-corrosive, non-conductive — ideal for damp basements, attics, crawlspaces
• Faster install — cuts with utility scissors, no tin-snip strikes through your hand
• 100 ft continuous roll — enough for several full residential installs

How to use it

1. Cut a length long enough to wrap the pipe with overlap at the fastener point
2. Wrap and overlap the strap around the pipe; nail through the pre-punched holes into joist or rafter
3. Use one strap every 4–6 ft on vertical runs, every 3–4 ft on horizontal runs
4. Combine with a Split Ring Hanger Kit at the primary fan-side support point for full system bracing
