This is to update you about a serious concern.  We have recently learned of the efforts of third parties to manufacture, distribute and/or sell diaphragms that imitate those of Aquasyn LLC.

Such imitation diaphragms are not authorized by Aquasyn LLC.

Aquasyn LLC is unable to ensure that counterfeit diaphragms meet the criteria that have been developed and formulated specifically for use in our diaphragm valves.   In order for Aquasyn’s patented Tork-Tite® Feet design to maintain the correct geometry and compression of the diaphragm, the use of Aquasyn’s proprietary materials formulation and diaphragm design is essential.   The combination of Aquasyn’s patented design and proprietary materials is key to providing dimensional stability throughout the life of the diaphragm and maintaining optimum performance of our valves.

Aquasyn LLC regards third party products as counterfeit and utilizing them in our valves will void any warranty for our products.  Accordingly, Aquasyn LLC shall not be responsible for any loss, damage, or injury that may result from the use of such unauthorized diaphragms in Aquasyn valves.

Aquasyn is committed to providing the highest quality diaphragms for use in our valves.  If you did not purchase Aquasyn diaphragms from Aquasyn LLC directly or from an authorized distributor and have questions as to its authenticity, please contact us at +1 (818) 350-0423 or

Aquasyn LLC was established in 1996 and we are very proud of our accomplishments. We thank all of our loyal customers and distributors for their ongoing support.

We value your assistance in our efforts to protect the reputation of Aquasyn LLC products.
