Gripline with Integrated Filter (Integrated Filtered Line)

The Gripline with Integrated Filter is a direct-replacement airline for MTW-style HPA engines. Engineered for clean, reliable airflow, this line features an internal filter to help prevent particulates reaching your regulator or engine, while maintaining flexible routing and a snug push-fit on standard barbed fittings.
