Seal failure in hydraulic circuits causes internal or external fluid bypass — reducing system pressure, increasing cycle times, and creating oil loss that breaches site environmental requirements. This seal ***** 161-7145 is manufactured to OEM dimension and material specification for reliable sealing at rated operating pressure.

Compatible Machines
– 161-7145

Why Choose This Seal ***** 161-7145
– OEM-matched cross-section, inner diameter, and outer diameter for correct groove fit
– Rated to operating pressure and temperature range of the original application
– Compatible with standard mineral hydraulic fluid types (specify application for FKM/Viton where required)

Heavy-Duty Construction
This seal ***** 161-7145 is manufactured using nBR or polyurethane construction for the primary application; FKM available for high-temperature circuits. Hardness matched to application groove tolerance. PTFE backup rings included where operating pressure requires anti-extrusion support. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Lubricate with clean hydraulic fluid before fitting — never use petroleum-based grease
– Inspect groove dimensions for wear
– Do not roll or fold seals during installation — use a cone or sleeve installation tool
