The WD-40 Specialist Silicone Lubricant is a spray which is great for use on high-pressure equipment. It displaces moisture and provides excellent lubrication, protecting and extending the life of your tools and equipment. As the spray is silicone-based, it is perfect for using on rubber parts like pipes, window seals, plumbing fittings and belts. You can even use it on metal, plastic and wood, without it leaving a stain. As well as protecting your tools and machines from rust, this silicone lubricant will repel dust, dirt, oil and grime. This is useful against dirt build-up that can create damaging residues. With just a coat of Silicone Lubricant, you can be sure that things will stay clean and conditioned, and functioning smoother for longer. With the Smart Straw applicator, you’ve got two ways to spray; use the flip up straw for hard to reach areas, such as inside chains, locks or rollers, then flip it down to use the wide angle spray eye for area coverage on surfaces. Whichever way you need to spray, you can rely on the clever 360° valve to work efficiently at every angle, even upside down.

This lubricant was previously packaged with a yellow top and yellow straw and marked "WD-40 Specialist High Performance Silicone Lubricant". Latest packaging is a red top and red straw and the can is marked "WD-40 Specialist Silicone Lubricant". The product specification, however, remains unchanged.
