How to Select the Right Size FKM VITON FPM High Pressure Seal for Oil and Gas Drilling Tools

Selecting the right size high pressure seal is critical for maintaining leak-free operation in oil and gas drilling equipment. Incorrect sizing can lead to extrusion, leakage, or premature seal failure. Here's how to get it right.

1. Measure Shaft and Bore Dimensions
Use precision tools to measure the diameter of the shaft and bore where the seal will be installed. Tolerances must match manufacturer recommendations.

2. Check Seal Design Type
Different applications require different cross-sections, such as O-rings, lip seals, or V-rings. Choose the appropriate geometry for the sealing environment.

3. Consider Thermal Expansion
Account for dimensional changes due to heat exposure. FKM maintains shape at high temperatures, but metal components may expand or contract.

4. Consult OEM Specifications
Always check the original equipment manufacturer’s documentation to ensure compatibility with approved seal sizes.

5. Use Certified Sizing Charts
Refer to ISO, AS568, or metric size charts for standard seal dimensions, especially in high precision applications.

6. Custom Seal Requirements
For specialized tools, consult seal manufacturers to produce custom FKM VITON FPM seals tailored to exact tool dimensions.

Conclusion
Accurate sizing of FKM VITON FPM seals ensures proper fit, long life, and optimal sealing in high pressure oilfield tools and machinery.
