O-Ring Squeeze Formula:
| From: | To: |
The O-Ring Squeeze calculation determines the compression ratio of an O-ring in a gland for water applications. Proper squeeze ensures effective sealing while preventing excessive deformation that could lead to failure.
The calculator uses the O-Ring Squeeze formula:
Where:
Explanation: The formula calculates the percentage compression of the O-ring by comparing the difference between cross-section diameter and gland depth relative to the original cross-section.
Details: Proper O-ring squeeze is critical for creating effective seals in water applications. Too little squeeze may cause leakage, while too much squeeze can lead to premature failure, extrusion, or difficulty in assembly.
Tips: Enter cross-section diameter and gland depth in millimeters. Both values must be positive numbers, with gland depth typically less than cross-section diameter for proper sealing.
Q1: What is the ideal O-ring squeeze for water applications?
A: Typically 15-30% compression for static seals in water applications, but specific requirements may vary based on material and operating conditions.
Q2: Can this calculator be used for other fluids?
A: While the formula is universal, recommended squeeze percentages may differ for other fluids based on chemical compatibility and pressure requirements.
Q3: What units should be used for measurements?
A: Millimeters are standard for O-ring dimensions. Ensure consistent units for both cross-section and gland depth measurements.
Q4: How does temperature affect O-ring squeeze?
A: Temperature changes can affect material properties and thermal expansion, which may alter the effective squeeze in operation.
Q5: What if the calculated squeeze is negative?
A: A negative value indicates the gland depth exceeds the cross-section diameter, which would prevent proper sealing and likely cause assembly issues.
