Buy seals for NZ preserving jars. Perfit dome seals work well on Agee Utility Jars and Agee Special jars for preserving. Perfit seals for agee jars work best when using the overflow method of bottling rather than the water-bath method. Use these seals together with the screw bands that are right for your jar. If you have Agee Utility jars you'll need green screw bands. If you have Agee Special jars you'll need gold screw bands. Each pack contains 12 seals. The seals are 85mm diameter.
