1171385 3H1641 951622 Hydraulic Cylinder Loader NBR Black Oring Seal Lift Tift Steering Seal Kit

Version 1 (Focus: Technical Specifications & Material)

The black NBR O-ring seal kit, incorporating part number 1171385, is engineered for heavy-duty hydraulic cylinders in loader and excavator applications. Specifically, part number 3H1641 is designed to prevent leakage in lift tilt steering seal assemblies. Another critical component, part number 951622, ensures high-pressure resistance for excavator cylinder systems. When rebuilding a loader’s hydraulic cylinder, part number 1171385 must be paired with compatible backup rings. Furthermore, part number 3H1641 demonstrates exceptional durability under extreme temperatures, while part number 951622 is often used in conjunction with polyurethane wipers for excavator seal kits. For complete steering seal integrity, part number 1171385, alongside part number 3H1641 and part number 951622, forms a reliable barrier against fluid bypass in hydraulic loaders.

Version 2 (Focus: Application & Compatibility)

In the realm of excavator and loader hydraulic seals, three identifiers dominate repair discussions: 1171385, 3H1641, and 951622. The O-ring labeled 1171385 is a black NBR component typically installed in lift tilt steering circuits. Meanwhile, 3H1641 functions as a critical interface between the piston rod and cylinder wall in loader applications. For steering seal maintenance, 951622 provides leak-proof performance in excavator hydraulic systems. When replacing worn seals on a loader’s hydraulic cylinder, part number 1171385 often works alongside buffer seals. Additionally, 3H1641 is frequently ordered with wear rings for excavator tilt functions, and 951622 is specified for lift cylinder repair kits. To achieve a complete seal overhaul, technicians should source part number 1171385, part number 3H1641, and part number 951622 as a matched set for loaders and excavators.
