Husqvarna 740421400 O-Ring Bs 4518 16.1x1.6 Nitrile Rubber

When your Husqvarna concrete saw needs a seal replacement to maintain hydraulic integrity, this nitrile rubber O-ring keeps your equipment running without leaks. The BS 4518 specification ensures proper fitment with 16.1mm outer diameter and 1.6mm cross-section for reliable sealing under operating pressure. Nitrile rubber construction resists petroleum-based hydraulic fluids and handles the temperature swings common on job sites. This genuine Husqvarna replacement part maintains factory tolerances and prevents downtime from fluid loss or contamination. Regular O-ring inspection and replacement extends pump life and maintains consistent cutting performance. Built for concrete cutting contractors and equipment maintenance technicians who need OEM components that fit right the first time.
