Product Description
The METZGER Screw Plug, transmission housing (8030064) is an original-equipment-quality mechanical fluid service fastener manufactured by METZGER. Positioned directly in the transmission housing port holes, its primary function is to seal the vital oil inspection or drainage channels within the gearbox casing. It keeps high-viscosity gear lubricants safely sealed inside the transaxle assembly while offering an airtight barrier against external humidity and debris. Engineered with a specialized self-centering tapered edge profile, it establishes a reliable metal-to-metal high-pressure seal without demanding additional soft copper compression washers.

⚠️ Technical Maintenance Tip: Because these plugs are made of zinc-plated steel and are screwed directly into cast aluminum transmission casings, they are susceptible to galvanic corrosion and road debris binding over long service intervals. Always clean the internal 17mm hex recess entirely before inserting your tool, and ensure the hex socket is fully seated to avoid stripping the soft internal corners during fluid drains. Torquing strictly to factory specifications is highly recommended.
