It is a model new kit, it will come with a box of 40pc. 224 plugs, 1 bottle 7oz quick dry Stream Seal Vulcanizing Fluid cat no. 770, one puncture clear out instrument, one plug set up instrument , one replacement needle for plug set up instrument and Allen crucial. To prevent the plug breaking set some fluid on clear out instrument to lubricate puncture hole right before installing the plug. Take away the plastic sleeve from plug and set some vulcanizing fluid on plug right before inserting the plug. I continue to keep only couple of Kits in inventory so the product or service is from a fresh batch at all periods. I get the Tech product or service every two months and exchange old inventory with more recent expiration date every time.
