How to Select and Install Composite Pipes for Stage III Vapor Recovery Systems

1. Why Pipe Selection Matters in Stage III Vapor Recovery Stage III vapor recovery systems are designed to capture fuel vapors at the dispenser nozzle and return them to the underground storage tank (UST) during refueling. Unlike traditional fuel piping, vapor recovery lines operate under slight vacuum or low pressure and must remain absolutely leak-tight […]
