O-Ring Size Measurement：

1. Inside Diameter (ID) Measurement:

Use calipers or an ID micrometer to measure the inside diameter of the O-ring.

Measurements should be made to ensure that the O-ring is not twisted or deformed.

Usually measure two or three different locations to ensure consistent dimensions.

Record the smallest measurement as this is usually the tightest dimension of the O-Ring during assembly.

2. Cross-section diameter (CS) measurement:

Use an OD micrometer or micrometer gauge to measure the cross-section diameter of the O-ring.

Take measurements at several different locations on the O-ring, usually at four equal points along the circumference.

Record the largest measurement, as this is usually the loosest dimension of the O-ring during assembly.

Product features

Simple structure: square cross-section design, simple structure, easy processing and installation.

Reliable sealing performance: rectangular cross-section can provide good contact pressure, reliable sealing performance.

Easy to install: Can be installed directly in the groove without special tools.

Resistant to wear and aging: High quality rubber material is selected, which has good resistance to wear and aging.

Various materials available: Different rubber materials can be selected according to different application environments, such as:

Nitrile Rubber (NBR): Oil, abrasion and heat resistant, suitable for general industrial applications.

Fluoroelastomer (FKM): High temperature and chemical resistant, suitable for harsh environments.

Silicone Rubber (VMQ): Resistant to high and low temperatures, ozone resistant, suitable for food, medical and other industries.

Hydrogenated Nitrile Butadiene Rubber (HNBR): High temperature, oil and chemical resistant, suitable for high performance applications.

Various sizes: Customised square ring rubber products are available in different sizes according to customers’ requirements.
