Premium Pepex Fluororubber Seals

Unlike conventional overhaul kits that use standard NBR rubber, DMR-Japan uses Pepex fluororubber (FKM) for critical sealing components.

Benefits include:

• Excellent heat resistance (up to approximately 230°C)
• Outstanding fuel and oil resistance
• Superior chemical resistance
• Excellent abrasion resistance
• Outstanding weather and ozone resistance
• Longer service life
• Extended maintenance intervals

Fluororubber is widely used in aerospace and high-performance engineering applications where durability and reliability are essential.

Nickel-Plated Needle Jets

The supplied needle jets feature a durable nickel-plated finish, providing significantly improved wear resistance compared to standard components.

This helps maintain:

• Accurate fuel metering
• Stable air/fuel ratios
• Consistent engine performance
• Longer service life

Benefits

A complete carburettor overhaul can help restore:

• Smooth idle
• Crisp throttle response
• Reliable cold starting
• Improved fuel economy
• Consistent fuel delivery
• Better overall engine performance

Replacing worn seals, float valves and metering components also helps eliminate fuel leaks and improves long-term reliability.
