We had some yellow jackets get in the house and the only way they could get to the 2nd floor master bedroom had to be through the ductwork. Just to be sure, I purchased a very tight circular screen but needed a fernco-like device that not only fit over the end of the PVC vent pipe but with an inside diameter that would allow the hard metal circular screen to fit and stay put. This worked absolutely perfectly! I take it off during winter not only because the yellow jackets are no longer active but when running the furnace, the vent not only carries out combustion gases but due to it being high efficiency, water vapor. If I left it in place, the tight screening would accumulate the water, it would freeze, block the exit, and carbon monoxide is not my friend. Anyway, this Fernco worked perfectly for something it was not even intended to do. ### ⭐⭐⭐⭐⭐ Great for use in a Radon mitigation system *by on Reviewed in Canada 5 August 2025* Using these in a Radon mitigation system helps with ease of maintenance ## Frequently Bought Together - Fernco P1056-44 Flexible PVC Pipe Coupling for Cast Iron, Plastic or Steel to Cast Iron, Plastic or Steel Connections - Fernco 1056-43 Coupling Flex 4X3 No Metal - Fernco 1056-33 Flexible Pipe Coupling 3” CI/Plastic/Steel to 3” CI/Plastic/Steel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/68406397-fernco-inc-p1056-44-4-inch-stock-coupling](https://www.desertcart.us/products/68406397-fernco-inc-p1056-44-4-inch-stock-coupling) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-17*
