Mastercool 92376 - 1/4 FL 2 oz. Dye Injector
Excellent method for adding refrigerant oil or large amounts of UV leak detection dye to the A/C system. Add oil by allowing a vacuum to pull it in after the evacuation process, or use refrigerant to push it in using the recharge system. Rugged all metal 2 oz canister. The "easy connect" models use a ball valve design attached directly to the end of the A/C hose. Includes auto shut-off valve on the outside hose.
