O Rings Seal Description

O-rings seals are circular elastomeric rings used to prevent leaks and maintain airtight or watertight seals in various industrial applications, such as engines, pipelines, and machinery. They function by being compressed between two mating surfaces, creating a barrier that blocks the passage of liquids or gases. O-rings are known for their versatility, durability, and effectiveness across a wide range of temperatures and pressures.

Specification of O Rings Seal

1. Material: O-rings can be made from various elastomeric materials, including Nitrile (NBR), (FKM), Silicone (VMQ), EPDM, and more.

• Size: O-rings come in different sizes, specified by their inner diameter (ID), outer diameter (OD), and cross-sectional diameter (CS).
• Hardness: Measured in durometer (Shore A or Shore D), indicating the material's resistance to indentation.
• Temperature Range: Specifies the temperature limits within which the O-ring can effectively function without deteriorating.
• Pressure Rating: Indicates the maximum pressure the O-ring can withstand without leaking or deforming.
• Compatibility: Specifies the types of fluids or chemicals the O-ring material is compatible with.
• Tolerance: Defines the acceptable deviation from the specified dimensions.
• Application: Describes the intended use or industry-specific requirements.
• Color: O-rings can be produced in various colors for identification or aesthetic purposes.
• Standards: O-rings can meet specific standards like AS568 (imperial) or ISO 3601 (metric) for consistent sizing.

O Rings Seal Materials

The market offers a variety of rubber O-ring materials tailored for diverse applications. Nitrile (NBR) excels in oil and fuel resistance. (FKM) handles high temperatures and chemicals.

NSF		NSF is specialized in standard setting, product testing and certification services in the fields of public health, safety and environmental protection, and is an authoritative body in the field of public health and safety
KTW		The supplier is required to comply with DVGW (German Gas and Water Association) Regulation W 270 "Propagation of microorganisms on Non-metallic materials". This standard mainly protects drinking water from contamination with biological impurities. All drinking water systems and excipients exported to Europe must be KTW certified. Therefore, if Chinese drinking water systems and excipients are to be exported to European countries, they must pass KTW certification. KTW has been authorized by the World Health Organization (WHO) for the certification of safe drinking water.
WRAS		WRAS(Water Regulations Advisory Scheme) certification refers to the Water Regulation Advisory Scheme. WRAS is the certification of the safety of drinking Water in the UK.
UL		Founded in 1894, UL has become one of the world's leading testing and certification organizations with a complete set of management systems, standard development and product certification procedures.
SGS		SGS certification refers to the service that SGS performs compliance certification on targets according to standards, regulations, customer requirements and other conditions. To carry out relevant certification, we must pass inspection, testing, authentication, certification and other means (SGS certification itself is not a certification, but refers to the certification service of SGS).
