Keep your gel blaster or airsoft gun seals airtight for longer with this premium non-white silicone grease specially formulated for rubber O-rings and airtight seals. Unlike ordinary white lithium greases that dry out, harden, or migrate, Stariver’s advanced formula stays put, stays effective, and never solidifies or volatilizes.

Why This Grease Stands Out

Non-Drying & Non-Volatile – Maintains consistent lubrication indefinitely without curing, evaporating, or breaking down
Strong Adsorption – Clings tightly to O-ring surfaces so it won’t wash away or fling off during rapid cycling
Wide Temperature Range – Performs flawlessly from -40°C to 250°C (-40°F to 482°F)
25 PSI Pressure Rated – Handles the demands of high-performance air seals
Insulating & Non-Conductive – Safe around electronics and metal parts
Nano-Grade PTFE Technology – Ultra-smooth surface, superior lubrication, heat dissipation, rust prevention, and long-term sealing
Premium Base – Made with German WACKER® silicone oil plus performance additives for excellent chemical stability and compatibility with rubber, metal, and plastic

Proven Performance on Toy Air Seals

Independently tested to significantly improve the stability and service life of toy piston air-seal components. Perfect for maintaining consistent FPS, reducing air leaks, and extending the lifespan of your gel blaster, airsoft gun, or other pneumatic hobby equipment.

Additional Benefits

Non-toxic, odorless, ozone-resistant, weather-resistant, and anti-aging
