Greases & Lubricants

Whether packing a wheel bearing, lubricating a door lock or any number of other applications, you are going to need the right lubricants or grease for the job. Repco stock the widest range of specialised lubricants and greases from CRC, WD40, Penrite, Castrol and more to ensure you have the right product at hand for any job around the house or workshop. Whether a dab, a squirt or a whole handful, here at Repco we have the grease or lubricant to keep everything moving.

Greases and lubricants are essential in any garage or workshop environment. They keep parts moving smoothly, protect against wear and corrosion, and help extend the life of tools, machinery, and vehicles. Knowing when to use which type makes maintenance more effective and keeps everything running without unexpected hiccups.

Silicone Spray: The Versatile Protector

Silicone spray is a go-to for quick, light lubrication and moisture protection. It works well on rubber seals, plastic parts, and even metal surfaces that don’t need heavy-duty grease. One of its strengths is that it won’t cause rubber to swell or degrade, making it suitable for door seals, weatherstrips, and hoses. It also repels moisture, which helps prevent rust on tools and metal fittings. While it’s handy for reducing squeaks and sticking parts, it’s not designed to handle heavy loads or high-friction areas.

WD-40: More Than Just a Water Displacer

WD-40 is often thought of as a universal fix-all, and while it does many jobs well, it’s important to understand what it really does. It’s primarily a water displacer, excellent for loosening rusted bolts, cleaning grime, and providing short-term lubrication. It can help free up stuck fasteners or protect surfaces from moisture temporarily. That said, it isn’t a heavy-duty lubricant or grease substitute, so relying on WD-40 for long-term lubrication, especially in high-stress environments, can lead to quicker wear. Using it as an initial cleaner and rust preventative before applying proper grease is a practical approach.

Lithium Grease: The Workshop Staple

Lithium grease is the heavy hitter for mechanical parts that face high pressure and friction. It’s commonly used on bearings, hinges, shafts, and other moving parts where metal contacts metal. This grease offers good temperature tolerance, water resistance, and excellent staying power, meaning it won’t easily wash away or break down under heavy use. When servicing car door hinges, wheel bearings, or industrial equipment, lithium grease is often the recommended choice. It’s worth noting that lithium grease is thicker and stickier than sprays, so it’s better suited to parts where you can apply it precisely and avoid excess mess.

Dielectric Grease: Electrical Protection Made Simple

Dielectric grease plays a specialised role in protecting electrical connections and terminals. Unlike regular grease, it’s designed to be non-conductive, preventing electrical shorts and corrosion caused by moisture or dirt. It’s commonly used on spark plug boots, battery terminals, and wiring connectors to keep moisture away and maintain reliable electrical contact. Applying dielectric grease doesn’t improve conductivity but rather protects components from damage, ensuring consistent performance. It’s a simple step that can save hours of troubleshooting later on.

Practical Uses and Tips for the Workshop

Choosing the right lubricant from Repco involves knowing where it will be used and what the conditions are like. For occasional squeaks or moisture protection on plastic and rubber, silicone spray is quick and clean. When rusted or stuck parts are involved, a targeted blast of WD-40 helps break things free, ideally followed by a heavier lubricant. For mechanical parts under load or frequent movement, lithium grease provides long-lasting protection and smooth function. Electrical connections benefit greatly from a thin coat of dielectric grease to fend off corrosion and moisture.

Proper application matters too. Clean the surface first to avoid trapping dirt or grit beneath the grease. Use the correct amount—not too little to be ineffective, but not so much that it attracts dust or drips unnecessarily. Correct storage of these products, in a cool, dry spot, means they last longer and perform consistently when called upon.
