The genuine Western 48985 Gland Nut Assembly secures the internal rod layout and maintains a leak-free fluid seal within 1-1/2 inch hydraulic cylinders. This factory replacement component includes the pre-installed low-friction pressure seals and wiper rings required to rebuild your ram box. Consequently, installing a fresh assembly prevents vertical blade drift and eliminates external oil loss when lifting or angling your plow. Because a compromised seal can rapidly drain your hydraulic fluid reservoir, parts specialists recommend swapping scored packing components during routine seasonal maintenance.
This plow-side hydraulic component provides an exact match for specific single-acting or double-acting rams. Because it is engineered with precise factory threading, the unit screws straight onto the cylinder body. Furthermore, the durable steel casing handles continuous high-pressure spikes when clearing dense, heavy snow. Therefore, your blade responds instantly every time you activate the cab remote.
