CowRC Udder Butter 40ml Syringe is a multi-purpose, fully waterproof grease engineered specifically to meet the high-load demands of radio control drivetrains and suspension components. While standard automotive and marine greases frequently contain petroleum distillates that degrade composite plastics and swell rubber O-rings, Udder Butter uses a specialised formula that remains completely safe across all materials common in the RC hobby. It provides smooth, long-lasting lubrication across ring and pinion gears, transmission gearboxes, portal axles, suspension pivots, and drivetrain bearings.

The formula is completely waterproof, meaning it will not emulsify, break down, or wash away when driving through mud, wet grass, streams, or saltwater environments. Unlike conventional greases that require packing heavy quantities into gearboxes, Udder Butter is highly adhesive and designed to cling directly to friction surfaces with minimal application. Packaged in a compact 40ml syringe, this format allows you to inject precise amounts of lubricant directly into tight gearcases, axle housings, and bearing shields without the mess of scooping by hand.

• Convenient 40ml syringe applicator provides pinpoint grease placement

• Fully waterproof formulation will not wash out in freshwater or saltwater conditions

• Refined fourth-generation formula proven across rigorous hobby use

• Safe on all RC plastics, composites, rubber seals, and silicone O-rings

• Highly tacky composition coats metal surfaces without requiring excessive volume

• Provides strong corrosion and rust resistance on exposed steel hardware

• Ideal for transmissions, axle assemblies, portal gears, and suspension linkages

• Genuine CowRC Product

• 1x CowRC Udder Butter Waterproof Grease (40ml Syringe)

• For gear applications, press the grease into the teeth to fill the gaps, then wipe away excess build-up. Heavy packing of gearboxes is not required.

• Not recommended for use inside 1/10 scale ball differentials, which require specialised ball diff grease.

• Not recommended for extra-large-scale vehicles weighing 36kg (80 lbs) or more.

• Store in a cool, dry place with the syringe cap securely fastened when not in use.
