Loosening and tightening hammer unions with the typical sledghammer is incredibly hard on the union - particularly the nut. Repeated hammer

strokes wear down the lugs, while missed strokes striking the union's body can cause hairline cracks which may go unnoticed until it splits with 

the force of pressure. Not to mention the risks to personal safety, and the integrity of sensitive equipment located nearby.
