Who It's For

These fittings are best for professional plumbers, building engineers and experienced DIYers who work with copper press systems and need to convert to 1-in male NPT connections. The press connection saves time on site and the brass construction suits a wide range of potable water and general plumbing uses.

Customers who require specialized materials, non-standard thread sizes, or have systems rated for pressures well above 300psi should look at alternative fittings or consult manufacturer specs. Also, installers who do not use press tools regularly may prefer traditional solder or threaded adapters.
