## Description

28mm Black Metal Screw Caps With Plastisol Liner - Pack of 15. Plastisol lined caps are the perfect option for hot-fill processes. After the liner is heated from the product temperature during canning, it will solidify and create an airtight, hermetic seal. Fits all jars and bottles with a 28mm (28-400) thread. We warrant our products in the event that they arrive damaged or defective - Covered under our 30 day hassle free replacement program! .

Review: Perfect fit - Great quality! Keep some on hand to replace broken plastic caps.
Review: Limited Use. - Works for the Northern mountain screw top bottles, but does not work with the recycled screw top wine bottles I originally wanted to use these for. Buyer beware: Apparently not all 28-400 wine bottles are the same. I've found that the plastic 28-400 screw caps work, so far, universally on any screw type wine bottle I've come accross.

## Questions & Answers

**Q: What is the width of the plastic caps?**
A: 28mm, or about an inch and 1/8th

**Q: will these fit spice jars?**
A: Don't know if these will fit your spice jars - it depends on the size of the jar.  The answer above, however, is definitely wrong.  These are NOT "wine bottle size".  They are the same size and thread as a standard plastic soda bottle.  If a soda bottle cap will fit, these are nicer looking and more permanent.  If a soda bottle cap won't fit, look for a different size.
