These are hydro-static drive breather vent tube caps to keep moisture and dirt out of the end of the breather tube.

They will fit any 3/4 inch breather hose 751-10474 and others. In the picture is the original (black) and the new replacement vent caps (gray) both will be gray.

The HG-70921, 70921 part numbers are for the vent cap. If the breather hose is 3/4 in diameter these will fit. They fit snug enough to prevent limbs and bushes from pulling these off during mowing.

Will consider bulk pricing for shops who want to offer these in their repair shop parts line. Please contact us.

Thanks for shopping with Ben's Creations.
