Description
Overview:
This Oil Filler Plug Extension is a genuine Villiers spare designed for use on industrial engines, notably the Villiers C25 and C30. It is a robust metal extension that threads securely into the existing oil filler port to raise the fill point, making access easier in confined engine bays and helping to keep the oil system clean during top-ups. Built for reliability in workshop and site conditions, it supports routine servicing and restoration work on vintage equipment. Supplied as unused old stock, it may show light tarnishing or cosmetic marks from storage, but remains fully functional. Identified by OEM No. 31348, this Genuine Part offers a correct fit and long service life when installed on compatible Villiers engines.
