Get reliable sealing performance from the start. FN LUBE is a petroleum-based O-Ring lubricant designed to reduce installation damage, prevent tearing, and extend seal life. This 2 oz tube delivers smooth, controlled lubrication that helps your team install O-Rings faster with fewer errors and less rework.
Built for maintenance teams, OEMs, and MRO operations, this beige, high-adhesion lubricant protects O-Rings during assembly and operation. The result is fewer leaks, reduced downtime, and more consistent performance across your equipment.
Operating temperature: -14° to +176°F (–26° to +80°C)
Material & Performance Details
FN LUBE is a petroleum-based grease engineered for compatibility with common elastomers and long-lasting lubrication performance. Made by Klüber Lubrication.
It provides strong surface cling, moisture resistance, and consistent lubrication in low-pressure and dynamic applications. Ideal for systems with reciprocating, slow rotary, or oscillating motion.
According to the technical datasheet, FN LUBE helps reduce installation damage such as pinching, tearing, and abrasion while improving seal longevity.
Chemical compatibility:
Excellent resistance to:
- Petroleum oils
- Hydraulic oils
- Moisture and water exposure
- General industrial lubricating environments
Limited capability with:
- High-temperature continuous applications above rated range
- Aggressive oxidizing environments
Not compatible with:
- Oxygen-rich systems
- Strong oxidizers
Sizes & Measurements
- Size: 2 oz Tube
- Part Number: FN-LUBE-2OZ
- Packaging: Squeeze Tube
- Form: Paste
Applications & Use Cases
FN LUBE is widely used in applications where proper O-Ring installation and lubrication are critical to performance and uptime:
- Hydraulic systems and cylinders
- Pneumatic systems and air tools
- Pumps, valves, and fittings
- Preventative maintenance programs
- Assembly lines requiring repeatable installs
- Low-speed rotary and reciprocating equipment
It is especially valuable in maintenance-heavy environments where reducing installation errors directly impacts uptime and cost.

FAQs
1. Why should I use an O-Ring lubricant during installation?
It reduces friction and prevents damage like cuts or twisting. This leads to fewer leaks and longer seal life.
2. Is FN LUBE compatible with common O-Ring materials?
Yes. It works well with NBR, FKM, FFKM, Neoprene, Polyurethane, and HNBR, making it a solid general-purpose option.
3. Can this be used in high-pressure systems?
It is best suited for low-pressure and moderate dynamic applications. For extreme pressure systems, we can help recommend a more specialized lubricant.
