【Premium Rubber】This grease dust cover is made of high-quality rubber material, which is soft, elastic, and wear-resistant. It is not only heat-resistant and anti-aging, but also not easily deformed, maintaining reliable sealing performance for a long time. It effectively delays corrosion and rust on metal vent screws, ensuring long-lasting durability
【Protective Function】This rubber dust cap tightly wraps around the exhaust screw, effectively blocking the intrusion of mud, dust, and rainwater, preventing oxidation and corrosion caused by external impurities, thus significantly extending the service life of brake system components. The ribbed design on the inner wall ensures a tight fit and prevents the cover from loosening or falling off
【Wide Compatibility】This brake bleed screw cap has an inner diameter of approximately 6-8 mm/0.22-0.31 inches and an outer diameter of approximately 12 mm/0.46 inches, perfectly fitting the exhaust screws of most cars, SUVs, trucks, motorcycles, and bicycles. It is recommended to check the original vehicle dimensions before purchasing to ensure optimal fit
【Easy to Install】 Installation is easy and requires no tools. Simply align the brake bleed screw valve connector cap with the bleed screw and press firmly until it's fully depressed. Its inner rib design securely holds it in place, ensuring it won't fall off even after long-term use. Its compact size also makes it easy to store and replace
【Package Includes】 The grease nipple cap dust cover set contains 18 dust caps for automotive brake vent screws, a sufficient quantity to meet your daily replacement needs
