Your hot melt adhesive system contains O-rings for sealing the hot melt flowing from your module through your hoses and applicator guns. O-rings provide a seal to keep glue from leaking out, which represents waste and takes time to clean up. O-rings need regular replacement as they crack and wear out due to regular use. If your hot melt adhesive system requires O-ring replacement, Keystone Industries is your source.

How to Choose the Right O-Rings

You can find this information in the owner’s manual of your hot melt equipment.
