Description
Overview:
This is a genuine Husqvarna carburettor sleeve (part number 503 44 51-01) for professional cut-off saws, made from a durable rubber material to provide a secure, airtight connection in the intake system. It sits between the carburettor and adjoining intake components to help prevent air leaks, maintain correct fuel mixture, and support smooth engine running under load. Designed for heavy site use, it offers an exact OEM fit on Husqvarna concrete saws including the 268K and 272K. By restoring a proper seal, it helps reduce hard starting, erratic idle, and loss of power that can result from a perished or cracked intake boot. Supplied as a direct replacement part, it is suitable for routine maintenance or a like-for-like repair when the original sleeve shows wear.
