Description
Overview:
The Pressure Sleeve for Stihl BG56C and BG66 is a genuine Stihl component designed to keep small two‐stroke machines running reliably. Made from a fuel-, oil- and heat-resistant elastomer, this compact sleeve creates a tight, durable seal on pressure/impulse connections within the engine and airbox assemblies. By preventing air leaks and maintaining a consistent pressure signal to the carburettor, it supports clean starting, steady idling and strong performance under load. Suitable for Stihl handheld blowers and a wide range of related tools across the same platform families, it is built to OEM dimensions for a precise push-fit. Manufacturer Part Number (MPN): 1121 893 2400. Genuine Stihl part for assured compatibility and service life.
