An O-ring groove is a concave or raised structure used to install an O-ring, usually in mechanical equipment, sealing systems, or pipe connections. The structure of the O-ring groove is designed to ensure that the O-ring is properly installed and effectively sealed. Manufacturer low price wholesale customization: 198-5653-1933 The following are common O-ring groove structure types: Rectangular slot structure: This is the simplest O-ring groove structure, usually a rectangular groove cut or milled on a mechanical part. The O-ring is placed in the groove and its cross section shape corresponds to the groove. Circular groove structure: A circular groove is a common O-ring groove structure commonly used for pipe connections, valves, and other sealing parts. The cross-section of the slot is semi-circular, matching the circular cross-section of the O-ring. Pear-shaped groove structure: Pear groove is a pear shaped O-ring groove structure with a cross section. This design provides better sealing performance and makes the O-rings easier to install and remove. T-slot structure: The T-slot is a "T" shaped structure with a cross section that can accommodate O-rings. This slot structure is often used in applications that require additional protection and support. U-shaped slot structure: A U-groove is a structure with a "U" shape in cross section, similar to a circular groove, but with an opening at the bottom. The U-groove is suitable for situations where the O-ring is required to slide in more easily during assembly. D-type slot structure: A D-shaped groove is a structure with a "D" shape in cross section, similar to a semicircular groove, but flat on one side. This structure leaves a flat surface on one side, making the O-ring easier to install and more flexible. The structural design of the O-ring groove depends on the specific application and design requirements. Selecting the appropriate groove structure can ensure that the O-ring can work properly during installation and use, providing reliable sealing performance. The size, shape and surface quality of the groove have an important impact on the tightness and life of the O-ring, so these factors need to be carefully considered when designing.
