New Year, New Facility


Construction of our new facility in Mills River, NC is complete! We are in the process of qualification of equipment and processes. We will begin assembling and shipping some orders from the new location as soon as the end of January. Your Product Application Specialist will notify you of location of origin before shipment. Thank you to all of our valued customers.

O-ring Options for Our Valves

O-rings are a key component of how our valves work. They provide an internal seal to keep the valve's poppet in place, as well as move forward off of the poppet’s cartridge seat to allow regulated flow through the valve. Additionally, we offer side seal valves with an exterior o-ring design that secures it in-line and provides an extra barrier against leaks, if needed.
Because o-rings are in constant contact with all liquids/gasses going through the valve, material selection is important. We offer standard o-ring materials to include:
  • Buna-N (Nitrile)
  • Ethylene-Propylene
  • Viton®
  • Silicone
  • Fluorosilicone
  • Aflas
We are also able to quickly source other o-ring materials including ultra-specialized o-rings, such as:
  • Kalrez®
  • Kimrez®
  • Chemraz®
  • Markez®
When viewed at a structural level, o-rings are complex, and their chemical makeup can be altered in a variety of ways to meet application-specific needs. We have encountered customers who have stated a particular o-ring material did not work in their application, but upon further examination a different variation of the same rubber proved to be successful. O-rings can be altered by viscosity, compression, curing options, and more - all depending on a customer's application needs.

We also offer o-rings by durometer, a hardness of rubber scale of 50 (soft) to 80 (hard). By looking at the o-ring's durometer, we can adjust a valve's pressure capabilities. For example, if you're looking for higher back pressure performance in our valves, we may recommend o-rings at a higher durometer.

The o-ring is one component of our valves that we can flexibly work with to ensure maximum performance for the most straightforward or complex systems. Combined with plastic body material and opening spring pressures, we have millions of possibilities to create the right valve for you. When building your custom valve, be sure to share all liquids/gasses coming into contact with the valve, application environment, and intended shelf life.
