The Parker VA075 - 75 is a general - purpose low - compression fluorocarbon (FKM, FPM) O - ring. It integrates good temperature resistance, broad fluid compatibility and stable mechanical properties, and is widely used in general industrial sealing scenarios. Here is a detailed overview based on its core specifications and performance characteristics:

Material Foundation: It is made of fluorocarbon rubber, a material renowned for its excellent resistance to high temperatures and chemicals. This enables the O - ring to resist the erosion of multiple common industrial fluids.

Hardness & Appearance: The durometer of this O - ring is 75 Shore A (with a tolerance of ±5 Shore A), which strikes a good balance between sealing elasticity and structural rigidity. It is black in color, a common color for industrial sealing parts that is easy to integrate into various equipment structures.

Low - Compression Feature: As a low - compression O - ring, it can maintain good sealing performance even under low compression conditions. This helps reduce wear caused by excessive compression between the O - ring and matching components, thereby extending the service life of both the seal and the associated equipment.

Temperature Adaptability: It has a wide operating temperature range of -15°F to 400°F. This allows it to work stably in both low - temperature cold environments and high - temperature working conditions such as some industrial heating systems, meeting the thermal requirements of most general - purpose industrial scenarios.

Fluid Compatibility: The O - ring is applicable to a broad range of fluid types. Referring to the performance of Parker's same - series fluorocarbon O - rings, it can effectively resist petroleum - based lubricating oils, hydraulic oil, fuels, natural gas and other common industrial fluids. However, it may not be compatible with glycol - based brake fluids, ammonia gas and strong alkalis.

Dimensional Specifications: For the specific size of the model, one common specification is an inside diameter of 10 - 1/2 inches and an outside diameter of 10 - 7/8 inches. Meanwhile, Parker's O - ring products are usually manufactured in accordance with international standards such as AS 568 B and DIN ISO 3601, ensuring good interchangeability and matching with standard - sized equipment grooves.

Applicable Scenarios: It is positioned as a general - purpose O - ring. Its low - compression design, coupled with temperature and chemical resistance, makes it suitable for static sealing scenarios in general industrial equipment, such as pipeline connections, valve components and hydraulic system joints. It can prevent fluid leakage and ensure the stable operation of the equipment.

Certification & Origin: The product is of North American origin. It meets UL certification standards, which is an important guarantee for its quality and safety in industrial applications involving fuels, gases and other media. This also makes it easier for the product to meet the procurement and application standards of North American - oriented industrial enterprises.

It does not have an internal lubrication design. This design is suitable for scenarios where additional lubricants may contaminate the working medium. And the material properties of fluorocarbon rubber itself can reduce certain frictional losses during static sealing, ensuring the reliability of the sealing effect without relying on internal lubrication.

Models: Parker's fluororubber O-rings with a hardness of 75 (VA075) offer excellent resistance to compression set while also possessing the broad chemical resistance expected of fluororubber materials.
