Mission-Critical Viton Rubber O-Rings & 100% Genuine FKM Seals
Engineered for aerospace powertrains, HPHT downhole drilling, and harsh chemical processing. We deliver 100% genuine, fully traceable viton rubber o rings with uncompromising resistance to extreme heat (up to 204°C/400°F), sour gas, and aggressive synthetic lubricants.
The Uncompromising Choice for High-Stakes Engineering
For Chemical Engineers and Powertrain Designers, standard sealing solutions are a liability. When you specify
viton rubber o rings, the greatest hidden risk to your multi-million dollar equipment is material adulteration. Cheap, diluted FKM blends will rapidly degrade under thermal cycling or aggressive chemical attack.
RiseUp guarantees absolute material integrity and performance for your most critical applications:
• 100% Genuine Virgin FKM (Full Traceability): We refuse to use recycled materials or diluted compounds. Our seals are formulated from premium virgin raw materials (such as Chemours Viton™), providing absolute material traceability and compliance with stringent aerospace (AMS) and petrochemical (API) standards.
• Defeating High-Temp Compression Set: A seal that flattens in a jet engine or a high-pressure valve is a catastrophic failure waiting to happen. Our Viton compounds are engineered to maintain their physical memory and elasticity, surviving thousands of hours of aggressive thermal cycling.
• Color & Hardness Precision (Mistake-Proofing): In high-stakes assembly lines, installing the wrong seal can be disastrous. We manufacture standard black, alongside distinct Brown and Green viton rubber o rings for instant visual identification. We also deliver exact hardness ratings (50-90 Shore A) for precision extrusion resistance.
• The Ultimate TCO (Total Cost of Ownership): For High-End Equipment Procurement, genuine Viton carries a premium upfront price. But when you factor in the massive liability of aerospace failures, deep-water drilling blowouts, or chemical plant downtime, a pure Viton seal is the most cost-effective insurance policy available.
Built for Extremes: The Science of Viton Heat & Chemical Resistance
In deep-water drilling equipment or automotive powertrains, relying on generic compatibility charts is a gamble. You need absolute certainty. Genuine viton rubber o rings are specifically formulated to survive where standard elastomers degrade, swell, or physically disintegrate.
Defeating High-Temperature Compression Set
The true test of a high-performance seal is not just surviving heat, but maintaining its “elastomeric memory” (the ability to bounce back after being squeezed). While standard NBR begins to harden and flatten at 120°C, our genuine FKM compounds exhibit exceptionally low compression set even during continuous exposure to 204°C (400°F) and intermittent spikes up to 230°C (450°F). This guarantees a permanent, leak-proof barrier in high-temperature engine blocks and reactor flanges.
Chemical Compatibility: Where Viton Excels (and Where It Fails)
To ensure maximum safety for your multi-million dollar equipment, we provide a transparent compatibility matrix. A pure
viton rubber o ring is your ultimate defense—except in a few highly specific chemical environments.

🟢 Excellent Resistance (Best Applications):
• Petroleum & Synthetic Oils: Outstanding performance in transmission fluids, engine oils, and harsh synthetic lubricants.
• Aviation Fuels & Hydrocarbons: Highly resistant to Jet Fuel (JP-8, Jet-A), aliphatic, and aromatic hydrocarbons (benzene, toluene).
• Petrochemical & Oilfield: Impervious to sour gas (H₂S) and explosive decompression environments (specific grades).
• Acids & Silicone Fluids: Excellent resistance to strong mineral acids and silicone greases.
🔴 Severe Incompatibility (Avoid These):
• Ketones: Acetone, MEK (Methyl Ethyl Ketone) will rapidly swell and destroy Viton.
• Amines & Anhydrous Ammonia: Commonly found in certain gas sweetening processes; will degrade standard FKM.
• Skydrol (Aviation Hydraulic Fluid): Do not use Viton. Engineering Tip: For Skydrol, specify our premium EPDM O-Rings instead.
• Superheated Steam: Standard Viton A will break down in high-temperature steam. (Requires specialized Viton ETP or peroxide-cured FKM).
Decoding Viton Grades: A, B, F, GLT & Beyond
For procurement managers and engineers, specifying a “Viton O-Ring” is often not enough. “Viton” is a family of fluoroelastomers (FKM), and selecting the wrong fluorine content or curing method (bisphenol vs. peroxide) can lead to premature failure in HPHT (High-Pressure, High-Temperature) or extreme chemical environments.
To simplify your engineering decisions, here is the RiseUp guide to selecting the exact viton rubber o ring grade for your specific application:
• Viton™ A (66% Fluorine) – The Industry Standard:
• Best For: General automotive, standard aerospace fuels, and general-purpose lubricants. This bisphenol-cured grade offers the best balance of cost and performance for most high-temperature static sealing.
• Viton™ B (68% Fluorine) – The Chemical Upgrade:
• Best For: Chemical processing and power generation. The increased fluorine content provides superior resistance to aggressive acids and chemical mixtures that would attack Type A.
• Viton™ F (70% Fluorine) – The Oxygenated Fuel Defender:
• Best For: Automotive fuel handling systems. Delivers maximum fluid resistance against oxygenated fuels (containing methanol or ethanol) and highly concentrated aqueous inorganic acids.
• Viton™ GLT / GFLT – The Arctic Performer:
• Best For: Aerospace actuators, deep-water subsea equipment, and oil drilling in freezing climates. Standard FKM becomes brittle in the cold. The GLT series maintains critical elastomeric flexibility down to -40°C (-40°F) while retaining full 200°C high-heat resistance.
• Viton™ ETP (Viton Extreme™) – The Ultimate Problem Solver:
• Best For: Environments that destroy standard FKM. ETP provides unique resistance to low molecular weight ketones, amines, and even high-temperature steam, offering performance approaching that of FFKM (Kalrez®) at a lower cost.
The ROI of Genuine FKM: Viton vs. Nitrile (NBR)
For procurement teams managing budgets for aerospace or petrochemical facilities, the unit price of a seal is merely a fraction of the Total Cost of Ownership (TCO). While standard Nitrile (NBR) is highly cost-effective for general-purpose hydraulics, specifying genuine viton rubber o rings is a strategic investment in equipment reliability.
Why justify the premium price of Viton? It comes down to extending the Mean Time Between Failures (MTBF):
• Thermal Lifespan: NBR begins to harden, crack, and permanently deform (compression set) around 120°C (250°F). In contrast, genuine Viton maintains its elastomeric memory continuously at 204°C (400°F). A single Viton seal can easily outlast five NBR replacements in high-heat powertrains.
• Aggressive Fluid Defense: Harsh synthetic lubricants, fuel additives, and sour gas will rapidly swell or degrade NBR, causing immediate extrusion or pressure loss. Viton remains chemically inert, ensuring the physical volume of the seal never fluctuates.
• Eliminating Unplanned Downtime: The true cost of a failed O-ring is never the rubber itself—it is the tens of thousands of dollars lost in halted chemical production, emergency maintenance labor, or catastrophic aerospace failures. By preventing these events, viton rubber o rings pay for themselves exponentially.
