Shock Subs

Designed to be compact and efficient, the purpose of a shock sub is to isolate the shock created by the impact of the down hole hammer from the rotary head, using a shock sub eliminates metal-to metal contact, the shock is absorbed internally by the 90 durometer rubber and grease packing.
