A well assembly device comprises an outer tubular sleeve with a first end and second end. An inner tubular member has a first end and a second end, and the inner tubular member is disposed within the outer tubular sleeve. The inner tubular member includes a screened portion at its second end. A tip is frictionally secured to the second end of the outer tubular sleeve, so that the outer tubular sleeve and the tip may selectively disengage.
