JLS Technician Black Waterkey Assortment

JLS Black Waterkey Corks are synthetic peel-and-stick waterkey cork seals.

• Standard Waterkey Corks are 4.6mm (.180”) thick.
• Thin Waterkey Corks are 3.4mm (.135”) thick.

Advantages: 

• The main advantage of using synthetic v. natural cork is that synthetic cork won’t deteriorate over time from water and saliva.
• Synthetic waterkey corks are much easier to install due to their peel-and-stick adhesive backing.
• Synthetic waterkey corks are more forgiving and will allow for more compression than either natural corks or neoprene.

“Everybody should be using synthetic corks.” – J.L. Smith
