The NIBCO PEX stainless steel sleeve collection provides essential components for secure connections in potable water and radiant heating systems. Each precision-formed sleeve is engineered to fit seamlessly over tubing, positioning perfectly over the ribs of insert fittings to create a reliable, leak-resistant seal when properly crimped. Designed with a positive stop and a visual locator port, these sleeves ensure accurate placement on the pipe during installation, reducing the risk of errors.
