Description
Overview:
This Oil Seal 13x19x4 is a Genuine Stihl part for small engine sealing on Stihl chainsaws, including the 009 and 044. It is made from durable, oil- and fuel-resistant elastomer designed to withstand heat, vibration, and continuous rotation around shafts. The seal prevents oil loss and unwanted air ingress at critical engine points, helping to maintain crankcase pressure, lubrication, and overall engine efficiency. With precise dimensions of 13 x 19 x 4 mm, it is designed for a snug, accurate fit in compatible housings. Use it during routine maintenance or rebuilds to restore proper sealing and protect internal components, keeping your saw running reliably under demanding cutting work.
