JLS Opti-Kork Waterkey Corks are synthetic peel-and-stick waterkey cork seals.
The “Opti-Kork” line was introduced in 2018 as an aesthetic alternative to our popular JLS Waterkey Corks which are still available to order. Since then, Opti-Korks have become our most popular 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
What is “Batch Built”?
Batch Built is a description we apply to our machined tools that are periodically made in batches.
Each time we make a new batch, the product’s design, function, specifications, and materials are reviewed with the design and production teams. We are constantly improving our tools and finding ways to make them more economically.
Although we work hard to ensure our essential tools, pads, parts and supplies are always available, Batch Built tools are not in stock at all times.
How can I order Batch Built tools?
If a Batch Built tool is out of stock it cannot be ordered, but you can enter your email address on the product page in the field “Email when stock available” and click “Notify Me”.
We don’t want to hold up orders that include Batch Built items if they cannot be delivered, particularly if those items are not yet on our production schedule and have no ETA.
