New 1425868 Seal GP Ring Replacement suitable for Caterpillar Equipment

The 1425868 seal keeps fluids contained and contaminants out where two surfaces meet or a shaft rotates. A sound seal maintains pressure, prevents leaks, and protects the components it isolates.

Please follow the installation steps provided below
1. Before starting, ensure the system is turned off and pressure-free 
2. Remove the worn-out seal carefully and clean the contact surface to remove any debris or residue 
3. Gently position the new seal in place, ensuring proper alignment before securing it 
4. After installation, check for leaks and confirm the fit 
Always follow your equipment’s service guide for accuracy.

Fitting the 1425868 correctly comes down to clean surfaces and following the manual sequence. Work through these steps:

1. Shut down and depressurize the system, then let it cool if needed
2. Remove the old seal and clean the bore and shaft surfaces
3. Inspect the sealing surface for scoring, pitting, or wear
4. Lightly lubricate the 1425868 as directed and fit it square to the bore
5. Seat it to the correct depth without distorting the lip, then check for leaks

The 1425868 is matched to particular Caterpillar equipment, so always verify the application against your parts reference before purchasing. Please reach out to Propel Parts for help verifying fitment.

Yes. Propel Parts supplies the 1425868 as a premium aftermarket part made to meet OEM specifications. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so you can fit it with confidence.

You may need to replace the seal if you notice 
1. Leaks
2. Fluid loss, or signs of wear such as cracking or deformation. 
Regular inspections can help you identify these issues early.

Replace the 1425868 whenever the assembly it serves is overhauled, or any time it shows wear, damage, or corrosion. Following the intervals in your service manual is the best guide.

When the 1425868 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:

• Visible fluid leaks or seepage at the joint
• Loss of system pressure
• Contamination found inside the assembly
• A hardened, cracked, or torn sealing surface

Replacing the 1425868 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance. Related hardware on our site includes 07000-13048 Seal O-Ring and 2314457 Gasket Ctp.
