Product description

The BH-9635 Oil Valve Stem Seal is a specialized component designed to prevent hydraulic fluid from leaking out around the moving stem of your lift's control valve. Replacing the Rotary FA349-3 and Weaver S-18957, this seal is critical for maintaining the internal pressure needed for consistent lifting. Over time, the repeated sliding action of the valve stem can wear down the seal material, resulting in "wet" valves and potentially dangerous oil pooling. SVI International's stem seal is made from durable elastomers that provide a tight, low-friction seal, ensuring smooth valve operation while keeping the hydraulic fluid exactly where it belongs. This is a vital replacement part for anyone performing a routine maintenance check or a full valve overhaul on Rotary or Weaver lifts.
