Recommended for Installation and Lubrication of O-Rings
Compatibility: broad range of elastomers including EPDM, FVMQ, NBR, FKM, and selected silicone materials
When you are installing O-Rings or sealing critical systems, the difference between success and failure often comes down to lubrication. FN Lube Plus is a high viscosity, silicone-based lubricant designed to protect your seals, reduce installation damage, and keep your systems running longer with less downtime.
This 2 oz tube delivers consistent, clean lubrication that stays in place under pressure. It is ideal for O-Rings, gaskets, and elastomer seals across a wide range of materials. With its clear, odorless formulation and high performance stability, you get predictable results every time without contaminating your system.
Operating temperature: -40° to +320°F (–40° to +160°C)
Material & Performance Details
FN Lube Plus is a silicone oil-based lubricant engineered for demanding sealing environments where reliability matters.
- High viscosity for strong film strength under pressure
- Chemically inert formulation that will not interfere with system fluids
- Moisture resistant and stays in place during installation
- Protects elastomers from ozone and environmental degradation
- Excellent adhesion for consistent lubrication during assembly
Chemical compatibility:
Excellent resistance to:
- Water and moisture
- Ozone and environmental exposure
- Most elastomers including EPDM, NBR, FKM, FVMQ
Limited capability with:
- Certain dynamic high-speed metal-on-metal lubrication applications
Not compatible with:
- Applications requiring petroleum-based lubrication compatibility
Sizes & Measurements
- Size: 2 oz Tube
- Part Number: FN-LUBE-PLUS-2OZ
- Form: High viscosity silicone lubricant
- Color: Clear / Colorless
- Odor: Odorless
Applications & Use Cases
This lubricant is built for real-world sealing challenges where installation damage and premature failure cost time and money.
Common uses include:
- O-Ring installation in hydraulic and pneumatic systems
- Assembly lubrication for valves, pumps, and fittings
- Vacuum systems where clean, non-reactive lubrication is required
- High-pressure sealing environments
- Maintenance and repair operations (MRO)
If your team installs O-Rings regularly, this product reduces pinching, tearing, and improper seating. That means fewer leaks, fewer callbacks, and more confidence in every install.

FAQs
1. Can this lubricant be used on all O-Ring materials?
Yes, it is compatible with most common elastomers including EPDM, Buna-N (NBR), Viton (FKM), and silicone.
2. Will this contaminate my system or fluids?
No. It is chemically inert and designed not to interfere with most system fluids or components.
3. Why use silicone lubricant instead of oil-based lubricants?
Silicone lubricants offer better temperature stability, longer life, and do not degrade rubber materials like some petroleum-based options.
