Our Drain Fitting Stopper Cap is designed to work with our standard drain fitting to allow for plugging of the flow of fluids from a drain pan. In instances where fluids are desired to be retained in the pan for a period and then evacuated in a controlled manner, the Fitting Cap can be used with our drain pan and drain fitting. The Drain Fitting Cap has a female threaded connection that will fit over the end out our Drain Fitting and tightly thread together.
