Loctite Lb 8104 Lubricant Silicone Grease 75ml
LOCTITE LB 8104 Lubricant Silicone Grease (75ml) is a commercial-grade, NSF H1-certified valve and packing lubricant engineered for high-performance sealing and lubrication across food processing and industrial fluid handling systems. Formulated from high-grade silicone and thickened with silica gel, LOCTITE 8104 provides superior protection for plastic and elastomeric components operating under harsh thermal conditions.
Key Features & Performance Benefits
- NSF H1 Certified: Registered under NSF Category H1 (Reg No. 122981) for incidental food contact in food processing and packaging lines.
- Broad Thermal Stability: Maintains consistent viscosity and protection across extreme operating temperatures from -40°C to +200°C.
- Elastomer & Plastic Compatibility: Prevents swelling, drying, or degradation of sensitive O-rings, rubber seals, gaskets, and plastic fittings.
- Heavy-Duty Sealing: Acts as an effective valve and packing grease, ensuring smooth actuation and leak prevention in hot and cold water systems.
- Assembly Assistance: Facilitates seamless installation and seat fitting of delicate seals during maintenance overhauls. Ensure surfaces are cleaned using Loctite 7063 prior to application.

Frequently Asked Questions
Is LOCTITE LB 8104 safe for direct contact with drinking water and food production lines?
Yes. LOCTITE LB 8104 holds an NSF H1 registration (Reg No. 122981), approving it for use as a lubricant with incidental food contact in and around food processing areas and potable water valves.
Can LOCTITE 8104 be used on oxygen systems or strong chemicals like chlorine?
No. LOCTITE LB 8104 is not recommended for pure oxygen or oxygen-enriched environments, nor should it be selected as a sealant/lubricant for strong oxidizing materials such as chlorine.
What operating temperature range does LOCTITE LB 8104 support?
LOCTITE LB 8104 is rated for continuous operation across a broad thermal range of -40°C to +200°C without losing its lubricating properties or drying out.
How should LOCTITE LB 8104 silicone grease be applied?
Apply directly onto clean components requiring lubrication. Avoid over-lubrication. Always ensure parts are free of dust and previous residues prior to application.
