The Nitrous Express poly purge line upgrade replaces stiff hard lines with flexible polyline to eliminate hard‑line bending issues during installation. It is specified as a purge line upgrade and is intended to simplify routing and reduce the need to bend rigid tubing while maintaining reliable purge function.
