Description
Overview:
The Villiers MK20/25 Cylinder Base Gasket (DM201) is a genuine Villiers sealing gasket that fits between the cylinder barrel and the crankcase on classic MK20 and MK25 petrol engines. Made from compressible, oil- and fuel-resistant gasket fibre, it provides a stable, gas‐tight joint under clamping pressure and heat. This helps maintain proper compression, prevents crankcase and oil leaks, and supports reliable engine performance. Suitable for many small machines powered by these engines-such as lawn mowers, rotavators, stationary generators, pumps, and light construction equipment-it is an ideal choice for rebuilds and maintenance. Supplied as unused vintage old stock, the gasket may show slight discolouration or storage marks, which are cosmetic only and do not affect function. Genuine Villiers quality ensures a precise fit and dependable sealing.
Key Features:
- Genuine Villiers part, Manufacturer Part Number DM201, for assured compatibility and fit
- Precisely cut bolt pattern and port layout for MK20, MK25 and C25 engines
- Compressible fibre construction for a uniform seal under cylinder base clamping loads
- Resistant to petrol, oil and typical small-engine operating temperatures
- Helps restore and maintain compression while reducing blow-by and seepage at the barrel base
- Supports smooth reassembly during top-end overhauls and routine servicing
- Stable sealing performance without swelling or rapid degradation in engine environments
- Unused vintage old stock (NOS); minor surface ageing may be visible but is cosmetic only
- Suited to classic garden and construction machinery using Villiers single-cylinder power units
Typical Applications:
Used during cylinder removal and refit, decoke services, and full top-end rebuilds on Villiers-powered equipment. Common on classic lawn and garden machinery, compact generators, site mixers, pumps and small plant where MK20, MK25 or C25 engines are fitted. Ensures leak-free operation after maintenance.
