Product Description

High-Quality Silicone Rubber O-Ring, a specialised sealing element, is designed to provide reliable sealing performance in a variety of demanding environments. This type of O-Ring is primarily made from Silicone Rubber, a synthetic rubber favoured for its superior physical and chemical properties.

Material properties
Temperature resistance: Silicone rubber has excellent temperature resistance and is able to maintain its elasticity over a wide range of temperatures, typically between -60°C and +200°C and higher.

Chemical stability: it is resistant to a wide range of chemicals, oils and solvents, although there is limited resistance to certain specific chemicals (e.g. ketones, esters).

Biocompatibility: Suitable for medical and food contact applications, as silicone rubber is non-toxic and does not cause allergic reactions.

Electrical insulation: Silicone rubber has good electrical insulation properties and is suitable for sealing electrical and electronic equipment.

Ageing resistance: Silicone rubber has excellent UV and ozone resistance, making it suitable for outdoor use.

Flexibility and resilience: Even at low temperatures, it maintains good flexibility and resilience, reducing permanent deformation.

Size and Specification
High quality Silicone Rubber O-Rings usually follow international standards such as AS568 (USA), ISO3601 (International), DIN3771 (Germany), etc. These standards specify the dimensions, tolerances and material properties of the O-Rings.

Manufacturing and Quality Control
Manufacturers use a precision moulding process to produce O-Rings, ensuring dimensional accuracy and material consistency. Quality control processes may include material testing, dimensional checks and performance verification to ensure that each O-Ring meets high standards.Customised Service
Depending on the specific application requirements, high quality silicone rubber O-Rings can be customised in terms of colour, hardness and dimensions to suit specific operating conditions and functional requirements.

When selecting and using High Quality Silicone Rubber O-Rings, it is important to consider the operating conditions including temperature, pressure, media type and dynamic or static applications to ensure the best sealing results and longest service life.
