Overview
The Aqualon 12492 – Stem Seat, A-Jet On/Off Valve – Replaces OMAX 307305 provides the sealing surface against which the A-Jet on/off valve stem closes. This component forms the primary shutoff interface inside the cutting head, allowing the valve to stop and start the high-pressure stream cleanly during operation.
What’s Included
Stem seat configured to replace OMAX 307305.
Purpose / Why It Matters
The stem seat is a critical sealing surface. If it becomes worn, indented, or damaged, the on/off valve may leak, fail to seal completely, or produce inconsistent jet starts. Replacing the stem seat restores a clean sealing interface, supporting reliable shutoff and consistent cutting performance.
Compatibility
