Our titanium tube plugs are made with Titanium nut and bolt assembly. We manufacture the collar and washers are made from a non-water soluble hard plastic called Hytrel and the Silicone parts are of a vulcanized silicone rubber.

These plugs are offered in either a double size (two silicone parts) or a single size (one silicone part). The single plugs are recommended for lower pressures and the doubles are for pressures between 60 psi and 150 psi.
