This FRIK kit includes a pair of the new LDVI (Low Durometer Vibration Isolating) couplings. These are specifically designed for radon mitigation applications. The patent pending LDVI couplings are molded with a softer, more flexible (low durometer) material as compared to standard plumbing couplings. This makes installation easier and providing superior vibration isolation.
- 2 anti-vibration couplers, u-shaped easy read manometer
- Designed specifically for radon mitigation applications
- Low durometer vibration isolation
- Coupler’s ledge holds the pipe in place
- Coupler’s ledge prevents direct pipe-fan contact
- Coupler’s ledge prevents from turbulent air inside coupler
- Superior noise vibration isolation
