Description

Winterize your 1-1/2″ threaded pool lines the easy way!

When air pressure is applied, the Bungee strap stretches to allow water or air to flow freely. When pressure is relieved, the bungee strap instantly retreats and seals with its unique triple o-ring seal. The technology is so reliable, it can even be used as a hydrostatic relief valve at any depth.

Wipe the seals with a little lubricant before installing.
