Buying Guide
What should I know about 70-450 jar lids?
70-450 lids fit standard wide-mouth jars with a 70-450 finish. They use Plastisol liners for a seal and a CT (continuous thread) threading system that ensures a secure closure. These lids are common for canning, candle making, and dry storage projects.
Which finish is best for canning versus crafts?
For food canning, white or silver lids are traditional and widely compatible. If you want decorative jars, rose gold or black finishes offer a modern look while still providing a secure seal. Always verify jar compatibility with the finish you choose.
How important is the liner type?
Plastisol liners provide a gasket-like seal and heat resistance for hot-fill canning. A safety button on some lids adds tamper-evident assurance. If you plan to vacuum seal or store foods long-term, liners that maintain a tight seal are essential.
What quantity should I buy?
For ongoing projects, choose higher counts to reduce reorder frequency. White CT lids in larger lots are useful for frequent canning, while mixed finishes suit seasonal gifts and crafts.
Are these lids compatible with all jars?
These lids are designed to fit jars with a 70-450 (G70) finish. Confirm the jar finish and thread compatibility before purchase to avoid fit issues.
Practical tips for use
- Inspect lids for dents or damaged threads before use.
