FPM O-Ring 355.19x3.53 FKM Viton Fluor

Industrial sealing ring for large-diameter applications

High chemical resistance and long service life

Main description

The FPM O-Ring 355.19x3.53 manufactured from FKM Viton fluor is a high-performance industrial sealing ring designed for demanding applications involving large diameters, aggressive media, and elevated operating temperatures. With an inner diameter of 355.19 mm and a cross-section of 3.53 mm, this O-Ring provides precise, reliable sealing in static and semi-dynamic assemblies where dimensional stability and long-term performance are essential.

FPM / FKM rubber is widely recognized for its excellent chemical resistance, particularly against oils, greases, fuels, hydraulic fluids, and many industrial chemicals. Compared to standard elastomers such as NBR, FPM offers significantly higher thermal stability, reduced compression set, and superior resistance to ageing. These properties make the O-Ring suitable for use as a primary static seal or as a supporting element in systems that also include rotary shaft seals, oil seals, or other technical sealing components.

The large diameter of the FPM O-Ring 355.19x3.53 makes it especially suitable for industrial sealing in heavy machinery, process equipment, pressure vessels, flanges, housings, and large mechanical assemblies. It is commonly used in hydraulic and pneumatic applications, where consistent sealing performance is required under fluctuating pressure and temperature conditions. The material ensures tight sealing while maintaining elasticity over extended service intervals.

This O-Ring is a reliable choice for B2B customers seeking high durability rubber gaskets for professional industrial environments. The FKM compound, also known under the trade name Viton, is a proven standard in industries where safety, performance, and resistance to harsh operating conditions are critical.
