Betterfit Element Selector!
The former Betafit line will now be called Betterfit, and will incorporate an exclusive outer wrap that not only improves performance, but also provides quality protection. It features a unique oval-hole design that improves flow for more efficient filtration, ensuring long system life and cost-savings. Look for this change to start taking effect after December 15th. This process will happen gradually, as we use up current inventory.

We are further dedicated to maintaining our position as a fluid power leader by satisfying the ever-changing needs of our customers, and to the evolving demands placed on hydraulic systems.

Many of our products satisfy ISO standards, as well as many other industry standards, certifications and benchmarks. However, the goal of our innovative product line is not just to meet these requirements - our aim is to exceed them.

In addition to increasing product performance, at HYDAC we also take on the role of finding ways in which our innovations can provide cost savings to our customers over the lifetime of the their equipment, and to assist them in creating more efficient system designs.
