AIR INLET SWIVALS
 |
| The air inlet pipe or sub is also made of a low carbon alloy steel and carburized to "File Hard" prox 62 Rockwell. This gives the rotating seal surface a long lasting smooth hard surface. One ring nut on each end provides even pressure to the packing. A lantern ring in the center of each packing distributes lubricant evenly. The Holte Air Inlet will adapt to all drill rigs and drill pipe. |
