Description
Overview:
The Cup Plug is a genuine Stihl spare for selected cold-water pressure washers, including the RE110PLUS and RE120PLUS. It is a small, hard‐wearing polymer plug designed to seal a machined port on the washer body or pump assembly, helping to maintain correct pressure and prevent leaks during operation. By keeping water and debris out of internal passages, it supports consistent performance and extends service life. Built for repeated use in wet, high‐pressure environments, the plug provides a stable, secure fit without complex tools. It is an ideal like‐for‐like replacement for worn or missing plugs on compatible Stihl models and is supplied to OEM specification under part number 4950 770 0501 for straightforward identification and ordering.
