The TerchPilet Bleed Oil Port Dust Plugs + Bleed Screw Rubber Caps is an essential protection kit for maintaining and preserving the performance of Shimano hydraulic road disc brake calipers. Designed for riders who prioritize clean, reliable, and long-lasting braking systems, this upgrade offers significantly improved sealing compared to standard factory caps.
Each oil port plug features a specialized barbed structure that locks securely into the port, resisting vibration, weather exposure. The bleed screw caps are made from the same durable silicone material, providing complete coverage and reliable sealing against dust, dirt, and moisture.
This kit is fully compatible with Shimano 105, Ultegra, and Dura-Ace calipers—including R7170, R8170, R9270, BR-M755, BR-R9270, and other related models. It serves as a direct replacement for common OEM components (Y2HW10000), making it ideal for daily riders, competitive cyclists, and professional mechanics.
Whether you are performing routine maintenance or replacing missing factory caps, this TerchPilet protective set helps prevent corrosion, extends component life, and ensures your hydraulic braking system remains clean, efficient, and ready for peak performance.
