Easily install or remove TR C1 and similar valve cores in Schrader style valve stems with the STEELMAN 75060-1 Valve Core Remover. This handy, pocket screwdriver sized tool fits all standard bore sized valve cores on tubed and tubeless tire systems on cars, trucks, motorcycles, bicycles, and more. Save money lost to flat tires and poor gas mileage caused by underinflated tires due to leaky or loose valve cores. The contoured, screwdriver style handle fits comfortably into your hand but is small enough to fit into most pockets, mountain bike / road cycling kit, or automotive emergency tool kit. Please note, this tool is not recommended for use in the installation of TPMS aluminum valve stems where proper torque of 4 inch-pounds is required. The Original Equipment Manufacturers (OEM) requires that the valve stem components and EPDM rubber seals are replaced every time a tire is serviced on vehicles with TPMS, making this an essential tool for anyone who does their own tire servicing!
