The Waterway TruSeal Air Control has a unique low profile top cap and is available in 2 lengths, short 2.5" or extra short 2" to help in restricted spaces.

The whole piece at the top moves when operated as opposed to just the handle on other models.

This Waterway True Seal air valve is designed to regulate the air coming to the jets, and therefore the intensity of the massage.
