Aluminum Sump Washer 50pc 21mm ID 27mm OD Subaru - PKTool 

The PKTool Aluminium Sump Washer 50 Piece Set (21mm ID x 27mm OD) is designed to provide a reliable and leak-free seal during routine oil servicing on compatible Subaru models. Precision manufactured with a 21mm inner diameter and 27mm outer diameter, these washers are ideal for oil drain plug applications, helping maintain proper sealing pressure and preventing oil leaks after servicing.

Constructed from high-quality aluminium, these washers are engineered to slightly compress under correct torque settings, forming a tight seal between the sump plug and oil pan surface. Aluminium washers are widely used in automotive servicing due to their lightweight properties, corrosion resistance, and ability to create a strong seal without damaging mating surfaces. Supplied in a convenient 50-piece bulk pack, this set is ideal for workshops, mechanics, fleet servicing, or Subaru enthusiasts who perform regular maintenance. Keeping replacement washers on hand ensures professional results and reduces the risk of reusing worn or flattened seals.
