FPM O-Ring 150x3.5 mm - High-Performance Viton Seal

Main Description

The FPM O-Ring 150x3.5 mm is a premium-quality, static sealing component made from fluoroelastomer (commonly known as Viton). Engineered for demanding industrial environments, this O-ring provides outstanding chemical resistance, thermal stability, and long-term durability. As a technical sealing ring, it’s designed to serve in applications where standard rubber gaskets fail due to aggressive media or high temperatures.

Crafted for industrial sealing, this O-ring is ideal for hydraulic systems, pneumatic lines, pumps, flanges, and other static joints. The 150 mm inner diameter combined with a cross-section of 3.5 mm offers a reliable and precise fit in large housings or cylinders that require a high level of sealing integrity.

Due to its material composition, the FPM O-Ring demonstrates excellent resistance to oils, fuels, solvents, and corrosive chemicals, making it suitable for static and low-dynamic sealing applications. Its high-temperature rating enables stable performance across a broad temperature range, reducing the need for frequent maintenance. In procurement terms, this O-ring represents a cost-effective solution that minimizes downtime and maximizes system reliability.

This sealing component is widely used in OEM systems, maintenance operations, and custom industrial builds. By integrating this O-ring into your system, you ensure long-lasting, leak-free performance even in the most challenging environments.

FAQ

1. What is FPM and why choose it for O-rings?
FPM (fluoroelastomer) offers superior chemical and thermal resistance compared to standard elastomers, making it ideal for aggressive media and high-temperature environments.

2. Can this O-Ring handle high pressure?
Yes — while designed primarily for static seals, its material strength and dimensional stability make it suitable for moderate-pressure applications when properly sized.

3. Is the 3.5 mm cross-section strong enough for industrial use?
Absolutely. A 3.5 mm cross-section provides a solid sealing surface while still allowing flexibility and compression to ensure a tight seal.

4. How do I store and handle FPM O-rings?
Store in a cool, dry place away from direct sunlight and ozone sources. Avoid folding or twisting the ring excessively.

5. What industries commonly use this O-Ring size and material?
Hydraulics, pneumatics, chemical processing, automotive underwriting covers, and any system exposed to oils, solvents, or high temperatures.
