O-Ring Gland Size Calculator

Calculate O-Ring Gland Size





Formula

To calculate the gland depth and width:

\[ D_g = D_o + C_a \]

Where:

Similarly, the gland width can be calculated by adding the O-Ring cross section diameter to the clearance allowance.

What is an O-Ring Gland?

An O-Ring gland is a specially designed groove or cavity where an O-Ring is seated to create a seal between two or more parts. The gland ensures that the O-Ring is compressed to the correct amount to provide an effective seal without causing damage to the O-Ring. The dimensions of the gland, including its depth and width, are critical to the performance of the O-Ring seal. Proper gland design helps to prevent leakage and ensures the longevity of the O-Ring in various applications, such as hydraulic systems, pneumatic systems, and static sealing applications.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ D_g = 2 + 0.5 = 2.5 \text{ mm} \]

The Gland Depth is 2.5 mm.

\[ W_g = 2 + 0.3 = 2.3 \text{ mm} \]

The Gland Width is 2.3 mm.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ D_g = 3 + 0.7 = 3.7 \text{ mm} \]

The Gland Depth is 3.7 mm.

\[ W_g = 3 + 0.4 = 3.4 \text{ mm} \]

The Gland Width is 3.4 mm.
