Shaun (Arizona, USA)100%The Double Order Catastrophe
My co-worker placed an order and wasn't sure it went through online. I later placed the same order thinking the previous order didn't go through. To my surprise both orders went through, and I needed to cancel one of the orders. I called and spoke with someone who instructed me someone would contact me about the situation. I was contacted by Misty and she said she would do her best to cancel one of the orders but not sure if she could because they were next day orders. A small tome later I received an email saying she was able to cancel one of the orders. Thank you to Misty and the entire Propel Parts Team. Greatly appreciated!! -

Frequently Asked Questions
What is the 1S6595 gasket used for?
The 1S6595 is a gasket that fills the gap between two surfaces to create a tight seal. It keeps fluids and combustion gases where they belong.
How do I install the 1S6595 gasket?
A reliable installation of the 1S6595 starts with inspection and ends with verification. Follow this process:
- Shut down, cool, and depressurize the assembly before opening it
- Remove the old gasket and scrape the surfaces fully clean
- Inspect both faces for warping, pitting, or scoring
- Position the new 1S6595 so all ports and bolt holes line up
- Torque the fasteners in the correct sequence and re-check for leaks
Which Caterpillar machines is the 1S6595 compatible with?
Compatibility for the 1S6595 gasket varies by machine and configuration, so cross-check it for your Caterpillar equipment before ordering. If you are unsure don't hesitate to reach out to Propel Parts for help verifying fitment.
Does the 1S6595 gasket meet performance standards?
Yes. The 1S6595 is engineered to meet OEM specifications for material, dimensions, and durability. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so the part performs the way it was designed to.
How often should the 1S6595 be replaced?
The 1S6595 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear.
What are the signs of a worn or failing 1S6595 gasket?
Catching a failing 1S6595 early prevents wider damage. The common warning signs include:
- External leaks at the mating joint
- Loss of pressure or compression
- Coolant, oil, or gas cross-contamination
- A crushed, blown, or hardened gasket on inspection
Why is the 1S6595 important, and what related parts work with it?
