The Oil Seal Extractor removes oil seals, plastic dip sticks, and glow plug seals, along w/ many other uses. Includes a replaceable drywall screw for new tip. Includes slide hammer for extra pulling force. This adapter attaches the drywall screw to the shaft for the slide hammer. When the tip becomes dull, simply replace with a new drywall screw, instead of buying an entire new oil seal extractor kit. ProMAXX Tool reinvented the Oil Seal Puller to be more effective and efficient saving technicians time and money. Other pullers use a tapered threaded front to penetrate and remove the seal. This is an old school approach to a common problem, factor in degradation of the tip, and the need to buy a replacement tool, leaves you with an expensive repair for an ineffective tool. Problem solved! Take a standard commercial construction drywall screw, and adapt it to a precision-made stainless-steel holder, and you have a new product with a replaceable tip that stays sharp every-time. We did not stop there. We offer the option of adding a convenient, high-impact slide hammer made from high-density hardened-steel. Small enough to fit anywhere, but powerful enough to get the job done fast. Ohâ?? and to protect the tool and your investment, we black-oxide coat it to prevent rust, corrosion, and to add lubricity to the slide hammer action. Now thatâ??s Quality, Productivity, and Precision delive
