Introducing the LikeLion 2-inch Flexible Tank Adapter, a revolutionary solution for attaching pipes to curved surfaces where traditional bulkhead fittings fall short. This innovative adapter is specifically designed for 1-inch Schedule 40 PVC pipes, with precise dimensions of 2-inch (50mm) internal diameter and 4-inch (100mm) outer diameter. Perfect for installation on storage drums, buckets, and other curved containers, these adapters create a reliable, liquid-tight seal even on irregular surfaces. Installation is straightforward, requiring only a 2-inch (50mm) hole saw opening, and the adapter accommodates wall thicknesses up to 3/8 inch (9mm). Built for durability, these adapters effectively handle pressure, suction, oils, greases, sewage, and waste while maintaining performance in both hot and cold conditions. The 2-pack ensures you have a spare on hand for multiple projects or future needs. Save time and resources with this versatile fitting that outperforms traditional bulkhead designs in challenging curved surface applications.
