This stainless steel tool makes installing pistons easy. Putting the connecting rod through first, simply place the piston (with rings) into the tapered end of the ring compressor. Tighten the compressor snugly around the base of the piston. Then lay the compressor flat on the engine cylinder bore. U.S. Pat. 6,427,301
