Description
Overview:
This pipe seal is a genuine Yanmar part designed for tight, leak-free sealing at engine pipe connections on Yanmar 4TNV84T-KWA and 4TNV98-VTBZ engines. It is a ring-style seal made from robust, heat- and oil-resistant material suitable for demanding engine environments. Used at unions where pipes meet housings or fittings, it helps prevent the escape of fluids such as diesel, engine oil, or coolant, protecting components and maintaining stable engine performance. Built to Yanmar OEM standards under part number 123907-11601, it offers the precise fit needed for reliable sealing in compact construction machinery, plant equipment, generators, and garden machinery using the TNV-series engines. Being a genuine part, it supports long service life and consistent performance with minimal maintenance.
