The Wacker Neuson Cock Assembly, 2-Way is a genuine OEM component designed for PT6Y and PT6YT series pumps, including PT6Y-AU and PT6YT-IN variants. As a direct Wacker Neuson OEM part, the is manufactured to the same standards as the original component installed at the factory, ensuring a correct fit and proper function right out of the box. This assembly is confirmed to fit across multiple PT6Y series configurations, making it the right choice whether you're servicing a standard PT6Y, a PT6YT, or a regional variant of the platform.
Key Features
- Genuine OEM Flow Control Integrity — Sourced directly from Wacker Neuson, this cock assembly maintains the precise valve seating and sealing tolerances required for consistent fluid direction control in pump applications.
- Drop-In Port Compatibility — Engineered to match the original mounting configuration and port dimensions of the PT6Y platform, allowing straightforward installation without modification to existing plumbing connections.
- Broad PT6Y Series Coverage — Fits PT6Y, PT6YT, PT6Y-AU, and PT6YT-IN models, covering both standard and regional variants of the PT6Y pump line.
- Leak-Free Valve Operation — A worn or failing cock assembly can allow uncontrolled fluid bypass or leakage, disrupting pump priming and flow direction. Replacing with a correct OEM unit restores dependable shut-off and directional control.
- Fuel System Compliance — On pump applications where this valve is part of the fuel circuit, using a genuine OEM assembly ensures correct material compatibility with fuel and helps maintain safe, compliant system operation.
A 2-way cock assembly is a manually operated valve that controls the flow of liquid through a single inlet and outlet path — either fully open to allow flow or fully closed to stop it. In pump and engine applications, this type of valve is commonly used to isolate the fuel supply or manage fluid routing during operation, maintenance, or storage. When the assembly wears, develops cracks, or the valve no longer seats properly, it can result in fuel or fluid leaks, loss of prime, or an inability to shut down fluid flow safely — making timely replacement essential to both performance and safety.
