ZTTO Universal Metal Connector Bicycle Oil Change and Oil Filling Tools Kit Bike Brake Repairing Tool - 2021 PRO Metal Connector

Features:
The connector can be quickly connected to the funnel or syringes with simple plugging. Through the accurate matching of the stopring and the clamping grooves, a free rotating sealing state is formed between the joint and the oiler.
Block-free funnel, which controls the opening and closing of the funnel and its use status without any sense. When the funnel is used, the oil circuit is opened, and when the funnel is finished used, the oil circuit is closed. Oil spillage caused by pressure release due to blockage is avoided.
The funnel neck is designed as a depressurization reducer, which reduces the mixing of oil and air by limiting the direction and flowrate of the brake oil entering the funnel. The brake oil is evenly distributed on the sidewall of the funnel body from the four wings, which can eliminate small bubbles more quickly.
Compatible with more types of brakes, equipped with dual oil injectors, without worrying about the oil injection port on the side, and flexible response to the brake oil injection problem.
