11mm x 21mm x 2.5mm Sump Sealing Washer - Rubber
An 11mm x 21mm x 2.5mm Sump Sealing Washer is a rubber washer commonly used in automotive applications, especially for creating a reliable seal around the oil sump plug in engines.
Inner Diameter (ID): 11mm – fits snugly around an 11mm sump plug.
Outer Diameter (OD): 21mm – ensures ample coverage and a secure fit in the sealing area.
Thickness: 2.5mm – provides durability and pressure resistance without compressing too much.
The rubber material offers flexibility, resists oil and heat, and prevents leaks by tightly sealing gaps around the sump plug. This washer helps keep oil in the sump, protecting the engine and maintaining optimal performance. It is also suitable for other sealing applications where oil or fluid resistance is necessary.
