Overview:
This genuine Husqvarna O-Ring is a precision sealing ring for SMART series concrete vibrators, helping to keep assemblies leak-free and running reliably. Manufactured from durable NBR (nitrile rubber) at 70 Shore hardness, it withstands oil, grease, vibration, and abrasive environments on construction sites. The ring measures 233 mm × 3 mm (9.17 × 0.12 in) and is engineered for a dependable fit on compatible units, including SMART 40 and SMART 48. It replaces OEM No. 4812 0507 27 and Husqvarna MPN 594621401.

As a genuine Husqvarna spare part, it supports correct tolerances and long service life in demanding use.
