Technical Specifications & Applications of FPM O-Ring 260x5 - High-Temperature, Chemical-Resistant Seal
The FPM O-Ring 260x5 (Viton / FKM) is a precision fluoroelastomer seal featuring an inner diameter (ID) of 260 mm and a cross-section (CS) of 5 mm. Designed for demanding industrial, chemical, and vacuum applications, it combines thermal stability, chemical resistance, and mechanical durability.
Key Features & Advantages:
-
Excellent resistance to oils, fuels, aromatic and aliphatic hydrocarbons
-
Wide operating temperature range (-20 °C to +200 °C; up to +205 °C in many formulations)
-
Low compression set, good elasticity under stress
-
Minimal swelling in hydrocarbon environments
-
Suitable for static sealing; with correct design and lubrication, usable in certain dynamic sealing contexts
-
Available in different hardness grades (e.g. 75 Shore A, 80 Shore A)

❓ FAQ (Frequently Asked Questions)
Q: What does “FPM” stand for in FPM O-Ring 260x5?
A: FPM is the ISO designation for fluoroelastomers (also known as FKM in the US), such as Viton®. It denotes a material with high resistance to heat, chemicals, and oils.
Q: What temperature range is safe for FPM O-Ring 260x5?
A: Typically from -20 °C up to +200 °C; many formulations can tolerate short peaks up to +205 °C depending on the compound.
Q: Is FPM O-Ring 260x5 safe for fuel and oil systems?
A: Yes — fluoroelastomer seals are well-suited for fuel, lubricant, and hydrocarbon environments due to their chemical resistance.
Q: Which hardness (Shore A) is ideal?
A: It depends on pressure and application: lower hardness (e.g. 75 Shore A) gives more flexibility; higher (e.g. 80 Shore A) enhances mechanical resistance under higher loads.
Q: How to install FPM O-Ring 260x5 without damaging it?
A: Use a thin coating of compatible lubricant, avoid sharp edges in grooves, stretch gently if needed (staying within elastic limits), and ensure correct groove design.
