If we're being honest, installing delicate (read soft) brass hydraulic hose needle inserts shouldn't be done with a hammer. It can damage both the insert and hose and result in a not-so-flush fit – drastically affecting brake performance.
The needle driver secures the end of hydraulic hose and allows for a gentle, precise, flush insertion of the needle every time with no damage to either hose or insert.
Compatible with both standard and Torx T10/T8 hose fittings (dual-ended tool fitting) - Ships with x2 pins
