About the product

1. The function of the gasket
Sealing effect: Prevents lubricating oil and cooling medium from leaking from the joint surface of the casing.

Shock absorption and buffering: Reduce the impact of vibration on the casing during equipment operation.

Compensation tolerance: To make up for minor unevenness during the processing or installation of the housing.

2. Common Materials
Rubber types: Nitrile Butadiene Rubber (NBR), Fluoro Rubber (FKM), etc., resistant to oil and high temperatures.

Metal composite materials: such as metal-coated rubber gaskets, are used in high-pressure and high-temperature environments.

Graphite or PTFE: suitable for corrosive media or extreme temperatures.

3. Steps for Replacing Gaskets
Shut down the machine and drain the medium: Ensure that there is no lubricating oil or coolant in the cooler.

Disassemble the housing: Loosen the bolts and carefully separate the housing to avoid damaging the sealing surface.

Clean the sealing surface: Remove the residue of the old gasket and check whether the sealing surface is flat and free of scratches.

Install new gaskets:

Confirm that the gasket model matches (in terms of size and material).

Apply the sealant evenly (if necessary).

Align it properly to avoid distortion or displacement.

Reassembly: Tighten the bolts diagonally in sequence to ensure even force distribution.

Pressure test: Check for leaks before restarting.

4. Common Issues and Solutions
Leakage: It may be caused by aging gaskets, improper installation or damage to the sealing surface.

Washers deformed: High temperature or excessive pressure may cause material failure.

Compatibility issue: Lubricating oil or coolant corrodes the gasket material.

5. Points to Note for Selection
Temperature Resistance: It should be compatible with the operating temperature range of the cooler.

Oil resistance: Ensure the material is compatible with lubricating oil (for example, fluororubber may be required for synthetic oil).

For high-pressure environments, metal-reinforced gaskets should be selected.

Dimensional accuracy: The thickness of the gasket and its inner/outer diameters must be consistent with the original factory specifications.

6. Maintenance Suggestions
Regularly inspect the gasket for cracks, hardening or compression deformation.

It is recommended to use original factory or equivalent specification parts when replacing.

Record the replacement time as part of preventive maintenance.
