Dsnaduo Oil Drain Plug Gasket Assortment — 330PCS 36 Sizes, Multi-Material Crush & Sealing Washers

The Dsnaduo 330-piece oil drain plug gasket assortment provides 36 common sizes in rubber, metal-rubber, aluminum, stainless steel, copper, fiber and nylon to replace many OEM drain plug washers and seals.

This comprehensive gasket kit is built for mechanics, DIYers and fleet owners who need the right crush washer or sealing washer on hand for fast oil changes and routine maintenance. Each material is chosen for specific sealing needs — soft rubbers for conformance, metal-rubber for threaded plugs, and hard metals like aluminum, copper and stainless for reliable crush sealing on threaded drain plugs across multiple vehicle makes and models.

Which vehicles and plugs does this Dsnaduo kit cover?

The assortment includes sizes that match popular OEM references, making it useful for many passenger cars, light trucks and motorcycles. It lists cross-references like N0138157, 11026-01M02, 94109-14000 and others so you can find the closest replacement washer quickly.

• Covers common M12–M24 plug threads and SAE fractions (1/2", 9/16", 11/16", 3/4").
• Includes VW/Audi-compatible aluminum and Mini Cooper copper sizes.
• Contains sizes noted for common OEM part numbers listed in the kit details.

What materials are included and when should I use each?

This kit groups gaskets by material so you can choose based on application: softer materials for flexible sealing, and harder metals for crush-style fittings. Selecting the right material helps prevent leaks without over-tightening or damaging the drain plug.

• Rubber: conforming seals for small deformations and repeated use where appropriate.
• Metal & rubber: composite washers for threaded plugs needing a reliable seal and vibration resistance.
• Aluminum, copper, stainless steel: crush washers used for permanent, single-use seals on many drain plugs.
• Fibre and nylon: non-metal options for older fittings or where softer sealing is required.

How is the assortment organized and how many of each size are included?

The kit contains 330 pieces organized into clear groups by material and size for quick selection during service. Quantities vary by size and material, with multiple pieces of the most common sizes to support several oil changes or multiple vehicles.

• Rubber: various sizes including 15 pcs of 20.3×11.8 mm and 15 pcs of 21.7×13.5 mm.
• Metal & rubber: multiple 24–26 mm sizes in 6–10 piece counts for M12–M18 fits.
• Aluminum & stainless: sets of 8–10 pieces across common diameters (19.9–28 mm).
• Copper, fibre, nylon: assorted part counts to match OEM replacements for Minis, Toyotas and other brands.

How should I pick and install the correct gasket to avoid leaks?

Match the outer and inner diameters and material type to the original washer or OEM reference when possible. Replace crush-style aluminum and copper washers each time the plug is removed; rubber and composite washers may be reusable if undamaged.

• Measure OD and ID of the original washer before selecting a replacement.
• Replace crush washers after removal; torque the drain plug to the vehicle manufacturer’s spec.
• Keep spare common sizes from this kit in your toolbox for quicker service.

Who this kit is for: mechanics, mobile technicians, automotive DIY enthusiasts and fleet maintenance teams who need a one-box solution for oil drain plug seals across many vehicles. If you service multiple makes or perform regular oil changes, the Dsnaduo 330PCS assortment minimizes downtime and prevents the wrong-washer guesswork during routine maintenance.
