"We recommend METALUB Valve Sealant G80 for applications requiring extended service intervals. Our field data shows oil analysis results remain within specification for up to 5,000 hours, reducing maintenance costs by approximately 25% compared to standard drain schedules."
Application Guide
Step-by-step instructions for optimal use of METALUB Valve Sealant G80 in Oil & Gas applications.
Preparation
Ensure the application surface is clean, dry, and free from contaminants. Remove any existing lubricant residues using appropriate cleaning agents. For Oilfield gate valves applications, verify equipment is at operating temperature.
Application Method
Apply METALUB Valve Sealant G80 using standard industrial equipment. For grease products, use automatic lubrication systems or manual grease guns. For liquid lubricants, ensure proper filling procedures and avoid contamination during transfer.
Recommended Dosage
Follow OEM recommendations for fill quantities. For Oil & Gas applications, typical re-lubrication intervals range from 1,000 to 5,000 operating hours depending on conditions. Monitor performance and adjust intervals based on actual operating parameters.
Performance Monitoring
Regularly inspect lubricant condition and equipment performance. Check for signs of degradation, contamination, or unusual wear. Schedule oil analysis every 6 months for critical applications to optimize maintenance intervals.
Storage Recommendations
- Store in a cool, dry place between 5°C and 35°C
- Keep containers sealed when not in use
- Avoid direct sunlight and moisture exposure
- Shelf life: 5 years from manufacture date when stored properly
Safety Information
- Refer to Safety Data Sheet (SDS) before use
- Use appropriate PPE: gloves and safety glasses
