This part is a Pentair 11 Scallop 2-1/4" Face Width, 1" Graphite Gray Spa Hot Tub Air Valve. The Valve Cap Width is approx. 2 1/4" and the Hole in the Spa Shell is approx. 1 5/8". The pipe that would glue into this valve would measure about 1 1/4" Outside Diameter.. Compare the measurements to be sure this is correct.
Note: These valves are new old stock but may have some dust or scuffs from storage on them.. They will be in good shape and working order but not perfect..
