The 304 stainless steel burp plug helps release air from the pail before the pressure plate seals on the lid. Pressure plate and burp plug are both necessary for closing plastic pails. This item is non-returnable.
To ensure a proper seal we will custom fit the closing tool for your specific application. Just call our Customer Service Experts at 1.847.961.5347 or email us for directions on where to send a sample of your container and lid.
