The CTA Injector Seal Extraction Kit, No. 7806, removes clogged or stuck diesel injector seals. The 2.2-lb slide hammer removes the more difficult seals by its design with an integrated hexagonal socket to screw the extractor into the seal. The simplicity of this extractor makes the removal quick and easy without any adjustments or risk of dropping parts into the cylinder. The kit includes two conical removers with double thread entry, which services both passenger and light duty utility vans and trucks.
