MOLYKOTE EM-30L

The Premium Grease for Vintage Audio Mechanisms

The “Secret Sauce” for Walkman and Cassette Deck Repair

If you restore or maintain vintage audio gear, you know the biggest threat is brittle, old plastic gears and mechanisms. Molykote EM-30L is the specialist lubricant trusted by professional repair technicians to restore smooth, quiet, and reliable function to delicate plastic-on-plastic and plastic-on-metal movements.

Key Benefits for Your Audio Gear

• Ultimate Plastic Safety: Specifically formulated to be compatible with virtually all plastics and elastomers found in Walkmans, cassette decks, and turntables. This prevents the chemical damage and premature aging that regular greases cause.
• Stops Sticky Mechanism Syndrome: Its high-performance synthetic formula resists oil separation (low bleed) and oxidation, meaning it will not gum up or seize over time like cheaper lubricants. Enjoy smooth function for years, not months.
• Silence the Grind: Reduces noise and friction on moving parts, eliminating the “grinding” or “sticking” sounds common in older, dry mechanisms.
• Silicone-Free Formula: Crucial for electronics! The silicone-free composition prevents contact point failures and keeps sensitive components clean.
• Long service life
• Compatible with most plastics
• Can be used for plastic/plastic contact, metal/metal contact and plastic/metal contact
• Low seepage, so it can be used in places wherein cleanliness is required

Technical Applications

Molykote EM-30L is perfectly suited for low to medium-fast moving components found in analog audio equipment.

• Cassette Deck/Walkman Mechanisms: Gears, sliders, cams, linkage points and door mechanisms
• CD/MiniDisc Player Trays: Sliding rail mechanisms

About Molykote

The Molykote brand was founded in 1948 by American scientist Alfred Sonntag, initially introducing the world’s first lubricants based on molybdenum disulfide (MoS2​). The primary focus of Molykote is providing Smart Lubrication solutions to solve difficult, severe-duty lubrication and technical design challenges in the automotive and industrial markets. They are well-known for producing a full line of high-quality specialty greases—along with anti-friction coatings, compounds, and pastes—designed to withstand extreme conditions like high temperatures, heavy loads, and corrosive environments, ultimately reducing friction and wear to enhance equipment reliability.
