The 1-1/2Copper Cap is a durable plumbing fitting designed to seal the end of a copper pipe, preventing leaks and ensuring a secure closure. Made from high-quality copper, it is widely used in residential, commercial, and industrial plumbing systems for both temporary and permanent pipe sealing. Copper caps are commonly used in water supply lines, HVAC systems, gas distribution, and fire sprinkler systems, providing a corrosion-resistant and long-lasting solution.
