Nozac Fountain Pen O-Rings

Used for restoring Conklin Nozacs. Our Viton O-rings are slightly firmer than the Buna-N and are especially formulated for long life in sliding applications like pistons.

2 each of four different sizes. Size 1 and 2 are used for standard size Nozacs and sizes 3 and 4 are used for the oversized Nozacs. Because the Nozac pen barrel is celluloid some shrinkage may have occurred and why we offer two o-ring sizes for each type.

8 O-rings total.
