Genuine Koshin Head Packing (NBR Rubber) — Part No. 0121450
Product Overview
The Genuine Koshin Head Packing (Part No. 0121450) is an essential OEM sealing gasket engineered specifically for Koshin KTH-80S (3-inch) and KTH-100S (4-inch) heavy-duty trash pumps powered by Honda engines.
Molded from durable, oil- and chemical-resistant NBR (Nitrile Butadiene Rubber), this heavy-duty perimeter gasket forms an airtight, fluid-tight seal between the upper Separate Head (P/N 0121437) and the lower main Pump Case (P/N 0121439). Replacing a worn, cracked, or stretched head packing is critical to preventing air leaks that ruin self-priming capabilities and fluid leaks during high-pressure operation.
