Press Fitting

Press fittings are factory-made connections consisting of a fitting body (copper or steel) with an elastomer seal and a pressing ring or collar. A battery-powered or pneumatic press tool compresses the ring onto the fitting, deforming it around the tubing and creating a permanent mechanical seal. No flame, no solder, no mess.

In the field, press systems cut assembly time and eliminate scorch risk on nearby materials—critical in tight spaces, near combustibles, or when fast turnovers matter. One operator can press fittings while another continues running pipe. The seal is reliable if you use the correct tool, correct fitting size, and don't reuse fittings. You're pressing copper-to-copper or steel-to-steel; mixing materials or pressing into wrong gauge tubing causes leaks.

Press fittings cost more per joint than solder but recoup the savings in labor and speed on large jobs. They're code-approved in most jurisdictions for potable and radiant applications, though some municipalities still require solder or sweat for certain work. Always verify local requirements and tooling before committing to a system. A bad press—incomplete or off-center—won't hold pressure, so battery voltage and press head maintenance matter.
