Tri-Clamp 1.5" Rotatable Gasket
$ 1.99

TC Gaskets are typically used in between a rotating racking arm and the ferrule.

The ultra smooth, hard surface of the rotatable gasket allows the arm to be rotated after only very slightly loosening the TC clamp, so the junction remains liquid tight.

Some brewers and winemakers prefer this style of gasket in all applications because they find the gaskets' rigidity helps make connecting the TC parts easier.
