 It’s Durable

With millions of connections already in service worldwide, press fitting is a proven technology. This precision-engineered process ensures consistent quality at every joint. And unlike brazing, each connection is backed by a manufacturer’s warranty.

Trust in a Proven Technology

Every connection is engineered to handle pressure, vibration, and thermal cycling—tested to tough standards and proven to perform on the jobsite, not just in the lab. Clean, consistent joints reduce callbacks and rework, ensuring long-term reliability in even the most demanding HVAC environments.
