Homelite NOS Welch Plug Cap 01212-57

This is a genuine Homelite New Old Stock (NOS) welch plug cap, part number 01212-57.

Welch plugs are press-in caps used to seal internal passages inside carburetors. This part was commonly installed on various Homelite carburetors, rather than being specific to a single chainsaw or trimmer model.

Homelite frequently reused the same welch plugs across multiple carburetor types, which is why official manuals often list this part simply as a carburetor component without model-specific fitment.

This plug is typically found on Tillotson and some Walbro carburetors used on vintage Homelite chainsaws and trimmers.

⚠️ Fitment varies by carburetor model.
Please compare this part to your original welch plug before ordering........
