What are the standard sizes of fluororubber for gasket?

Hey there! As a supplier of fluororubber for gaskets, I often get asked about the standard sizes of this amazing material. So, I thought I'd put together this blog post to share some insights and help you understand what to expect.

First off, let's talk a bit about fluororubber. It's a super tough and durable material that's known for its excellent resistance to heat, chemicals, and oils. That's why it's a popular choice for gaskets in a wide range of industries, from automotive to aerospace, and even in some consumer products.

Now, when it comes to standard sizes, there isn't a one - size - fits - all answer. Fluororubber gaskets come in a variety of shapes and dimensions, depending on the specific application.

Common Shapes and Their Sizes

O - Rings

O - rings are one of the most common types of gaskets made from fluororubber. They're circular in shape and are used to create a seal between two parts. The size of an O - ring is typically defined by its inner diameter (ID) and its cross - sectional diameter (CS).

The inner diameter can range from just a few millimeters for small, precision applications to several inches for larger industrial uses. For example, in some electronic devices, you might find O - rings with an inner diameter of 3 - 5 mm. On the other hand, in heavy - duty machinery, O - rings with an inner diameter of 50 mm or more are not uncommon.

The cross - sectional diameter also varies. Common CS values are around 1.8 mm, 2.62 mm, 3.53 mm, and 5.33 mm. These values are standardized in many industries, making it easier to find the right O - ring for your needs.

Rectangular Gaskets

Rectangular gaskets are used in applications where a flat, square, or rectangular seal is required. The size of a rectangular gasket is defined by its length, width, and thickness.

Length and width can vary widely, from a few centimeters for small appliances to several meters for large industrial equipment. Thickness usually ranges from 1 mm to 10 mm, depending on the pressure and the type of seal required. For example, a gasket used in a low - pressure application might be 1 - 2 mm thick, while a gasket for a high - pressure system could be 5 - 10 mm thick.

Custom - Shaped Gaskets

In addition to the standard shapes, there are also custom - shaped gaskets. These are designed to fit specific parts or equipment. The size of a custom - shaped gasket is determined by the dimensions of the mating surfaces. We often work with our customers to create these custom gaskets, ensuring a perfect fit for their unique applications.

Factors Affecting Size Selection

Application Requirements

The first factor to consider when choosing the size of a fluororubber gasket is the application. If it's for a high - temperature environment, you might need a thicker gasket to ensure proper sealing. For a chemical - resistant application, the material quality and the size might need to be adjusted to withstand the specific chemicals involved.

Pressure and Temperature

The pressure and temperature in the system where the gasket will be used play a crucial role in size selection. Higher pressures usually require thicker gaskets to prevent leakage. Similarly, high - temperature applications might need larger cross - sectional dimensions to maintain their sealing properties.

Mating Surface Dimensions

The dimensions of the mating surfaces are also important. The gasket needs to fit snugly between the two surfaces to create an effective seal. If the mating surfaces are not flat or have irregular shapes, a custom - sized gasket might be necessary.
