Automotive replacement seals that aim to stop leaks during oil, gearbox and transmission drain operations, promising a repeatable crush fit each time. Practical reassurance for home mechanics and workshops who want tidy, reliable services. Are Partuto Engine Oil Crush Washers Drain Gaskets the straightforward fix for messy drips and repeated seal failures?
⚡ At a Glance
- • Seal Performance: Aluminium alloy forms a crush-fit seal that conforms to plug threads and mating surfaces.
- • Best for: DIY mechanics and garages performing oil, gearbox and transmission drain or fill services.
- • Not ideal for: Applications that require a different inner or outer diameter than 18mm I.D. / 25.5mm O.D.
Aluminium alloy crush washers supplied as a 10-piece pack, sized for common drain and fill plugs. Dimensions listed include an 18mm inner diameter, 25.5mm outer diameter and 2mm thickness.
Leak-free drains – With aluminium alloy crush washers
Aluminium deforms under torque to fill gaps between a plug face and mating surface, creating a mechanical seal by metal-to-metal contact. The 2mm thickness ensures predictable compression when the plug is tightened to specification.
A reliable metal-to-metal crush seal reduces the chance of slow leaks after oil or gearbox changes. The predictable deformation helps workshops avoid repeat visits to retighten or replace seals.
Broad compatibility for common plugs – Thanks to specified 18mm I.D. sizing
An 18mm inner bore matches many standard drain and fill plug diameters, while the 25.5mm outer diameter provides sufficient flange to compress against the sump or gearbox face. The sizing supports use on both fill and drain locations where dimensions match.
Fits a range of vehicles without modification when bores match the stated measurements, including successful use on MX5 NC gearbox and differential applications. Quick visual checks of plug bore diameter confirm suitability before fitting.
Service-ready supply – With a 10-piece pack
Multiple washers are included to cover several oil or filter services, allowing one pack to supply repeat maintenance jobs. Bulk quantity suits routine servicing routines in a home garage or small workshop.
A ten-strong set keeps spares on hand for scheduled maintenance and emergency replacements. Fewer trips to suppliers are needed during a servicing session.
