Roller Pad Cap

This object is a gym foam roller end cap (also known as a roller pad cap or pipe end cap), a small but essential component used to secure the cylindrical foam pads found on various strength training machines. Typically made from durable plastic like ABS or heavy-duty rubber, the cap features a wide, circular face and a "stepped" or ribbed inner neck designed to be hammered or pressed into the hollow metal tubing of the equipment.
