Replacement optic corks are essential for any bar that regularly cleans their optics! Which all bars must do to ensure their drink dispensing is hygiene. Even though our optic measures are designed to be hardwearing and long lasting, the optic corks will still need replacing every now and then. Ensure you have a spare optic cork available, as optic corks do wear over time. Optic corks are part of a large range of bar supplies stocked by Pattersons Bar Supplies. Part of our Spirit Dispensers & Spirit Measures department. For optic measures and optic wall brackets browse our departments within our bar equipment range.
