Hydraulic Jack Knob

Press-fit knob for pressure relief on hydraulic jacks. Use on hydraulic presses, tube benders, or plain old bottle jacks. This fits the flared style of jack valve pictured. Not for those with the rollpin punched through the plug. Often these come in different sizes and you may need to scale the model accordingly. There are 3 models here, one that fits an old 20ton NAPA jack, one that fits a smaller Torin bottle jack, and the initial model that fits the NAPA jack but is shallower. Measure your jack and the model. I can rework as needed.
