The PERRIN aluminum coupler tube is a fabrication tube measuring 2.75 in. OD by 2.875 in. long intended for custom hose and intercooler plumbing or repair projects. As a simple, durable connector it provides a clean, repeatable splice for tubing assemblies in charge piping or coolant runs; size and material suit many custom builds where an aluminum coupler is needed to join sections reliably during fabrication work.
