Lisle 39810 Hydraulic Clutch Line Disconnect Tool

Late-model manual-transmission clutch hydraulics use a plastic quick-connect coupling where the line meets the slave cylinder, master cylinder, or concentric release bearing. To release it you have to push a spring-collar retainer back evenly around the whole fitting at once. Do it with a screwdriver or a pick and you split the collar, gouge the line, or crack the plastic body and turn a 0 hose into a bleed-and-replace headache. This tool is a curved steel spring band with a handle that wraps the coupling, compresses the retainer squarely, and lets the line pop free in a couple of seconds.

It is built for the GM-style clutch line couplings found on Chevy and GMC trucks and cars running a hydraulic clutch, and it also works the Ford hydraulic clutch line connections. The handle is what separates it from the bare-band tools: you get leverage and a place to hold on in a tight bellhousing area instead of pinching your fingers against the trans tunnel.

Use it any time you are pulling a transmission, replacing a slave or master cylinder, or swapping a leaking clutch line. Slip the band over the coupling, seat it against the shoulder of the retainer, squeeze the collar in, and pull the line straight out. No cutting, no prying, and the fitting stays reusable so the connection seals when it goes back together.
