Product Description
COONIUM 8-Pack Road Bike Hydraulic Disc Brake Bleed Nipple & Screw Dust Covers – Premium Rubber Oil Nozzle Caps for Shimano 105 R7170, Ultegra R8170, Dura-Ace R9270 Caliper Protection
- CUSTOM FIT FOR SHIMANO 12-SPEED: Specifically engineered for the latest generation of Shimano road hydraulic disc brake calipers. Fully compatible with 105 (R7170), Ultegra (R8170), and Dura-Ace (R9270) groupsets, ensuring a perfect seal unlike generic universal caps.
- SECURE "BARB" LOCKING DESIGN: Never lose a dust cap on a ride again. The Oil Nipple Cover features an internal inverted hook/barb structure that snaps securely onto the caliper fitting. This creates a tight hold that resists vibration and prevents the cap from falling off during rough rides.
- TOTAL CALIPER PROTECTION: Essential for maintaining braking performance. These rubber covers seal out dust, mud, and moisture from entering your bleed ports while preventing residual brake fluid from leaking out and contaminating your brake pads or frame.
- PACKAGE CONTENT: (4X Oil Nipple Dust Covers): 9mm cap / 5.5mm ID. (4X Oil Screws Dust Covers): 8mm cap / 3.5mm ID. Made from high-quality, durable rubber that resists tearing and weathering. Includes 8 pieces in total per pack.
