Hydraulic Cylinder Seal Repair Kit for Cross & Hydroline 4 Inch Bore 1-1/4 Inch Rod Cylinders

Description

When your hydraulic cylinder starts seeping fluid or loses pressure, it’s not just an annoyance—it’s costing you time and money every day. A leaking cylinder means less power for your loader, three-point hitch that won’t hold position, and hydraulic fluid pooling where it shouldn’t. This complete seal repair kit gets your Cross or Hydroline cylinder back to like-new condition so you can get back to work with confidence.

What You’re Getting

• Complete rebuild kit with everything needed—no trips back to town for missing parts
• High-performance loaded U-cup seal that handles the pressure spikes of real farm work
• Metal clad wiper seal that keeps dirt and debris out of your cylinder
• Five O-rings and two back-up rings for complete sealing throughout the cylinder
• Quality seals designed specifically for hydraulic service and farm conditions

Built for Real Farm Work

This kit fits Cross and Hydroline hydraulic cylinders with 4-inch bore and 1-1/4-inch rod dimensions. These are common sizes found on loaders, three-point systems, and implement cylinders across many tractor brands. Whether you’re running a compact tractor with a front-end loader or operating larger equipment, these cylinder sizes handle everything from light material handling to heavy lifting tasks.

Made to Last

Farm hydraulics take a beating from pressure spikes, temperature swings, and contamination that would kill lesser seals. These aren’t cheap aftermarket seals that fail in a season. The loaded U-cup design provides superior sealing under pressure while the metal clad wiper keeps contaminants out. Quality materials resist the heat and pressure cycles that come with hard work.

Installation Notes

Cylinder rebuilding requires absolute cleanliness—any dirt or debris will ruin new seals immediately. Take pictures during disassembly so you remember where everything goes. Inspect the cylinder bore for scoring that could damage new seals, and always use proper seal installation tools to avoid nicking the sealing surfaces. A little hydraulic fluid on the seals during assembly makes installation easier and prevents damage.
