3 piece air-water hose adapter for liquid filling tube or tubeless tires for weight or ballast. Adapter attaches to a garden hose, it has common female garden hose threads. Screws directly on TR218 modern tractor tubes or TR618 tubeless tractor stems. Has an air bleed for releasing built up air pressure while filling without disconnecting the hose. Also includes two thread adapters. One screws on the external valve cap threads of any standard tire valve such as TR13 or TR15 tube stems or standard tubeless valve stems. The other adapter is for the old style antique tractor stems that had the non-fast fill TR218 stem with CH1 core housing.

To fill a tire you simply jack it up so it is suspended with no weight on it. Turn the stem to the top and let the air pressure completely out. Attach the adapter and pump it full of a freeze proof liquid such as calcium chloride, methanol/water mix, beet juice, etc. As the tire fills it will build up air pressure, stop the pump every few minutes and use the air bleed to release built up pressure. Typical fill is 80% or valve level which means you fill until the liquid is level with the stem at the top. Reinstall the core or core housing and inflate to pressure.
