Keyser elbow connector completely solves the vibratory directional problem at the pumps or any other location where the piping must make a right angle turn as it leaves the equipment. The Keyser neoprene elbow accepts motion in all modes without difficulty as the sphere is at the curvature of the connector and the flow through length is even longer than the twin sphere.Rather than taking additional space or using additional fittings, the elbow joint actually substitutes for the cast welded elbow that would ordinarily have to be used anyway.

The cost of Keyser rubber bellow is comparable to the steel it replaces and certainly less than the cost of a steel elbow plus a straight line connector. When Keyser rubber elbows are used, the pump foundation need no longer be made large enough to support the base elbows and this reduces the cost of the foundation. Because the piping must be properly supported from above rather than rest on the pump foundation, there is better chance that the pump foundation can operate properly. The reduced foundation weight is often important in lightweight equipment rooms as well.
