QuickFitting 1/2 in. Press in. FNPT copper adapter is the fast, flame-free connection you need to bridge a pressed copper run with a threaded pipe. Crafted from robust copper, this adapter delivers reliable performance for both indoor installations and buried applications, making it a smart choice for potable water and irrigation projects.
-
Two dependable connection types in one: a 1/2 in. press end for copper tubing on one side and a female FNPT threaded end on the other, enabling seamless transitions between copper piping and standard threaded components.
-
Underground rated: built to withstand buried or exterior piping conditions, helping your installations resist soil moisture and shifting soil environments.
-
NSF-listed for potable water: certified material compatibility and safety for drinking water systems, giving you confidence in every use.
-
Flame-free, tool-assisted installation: enjoy faster, cleaner joints with a copper press tool—no solder, no torch, and less heat exposure on nearby materials.
-
Compact, versatile solution: ideal for retrofit jobs, irrigation mains, and tight spaces where traditional soldered or threaded adapters are impractical.
Typical use scenarios include retrofitting an existing copper irrigation line to connect to a threaded valve or fitting, or extending a potable water run where a pressed copper segment must meet a standard NPT connection. This adapter helps you avoid complex soldering, reduces on-site heat risks, and delivers a durable, leak-resistant joint when paired with the appropriate press tools and sealant on the threaded side.
- Prepare the copper tube: cut square, deburr, and ensure a clean, dry surface for the press end.
- Secure the 1/2 in. copper tube into the press end and use a compatible press tool to crimp until the sleeve seats securely.
- On the FNPT side, apply plumber’s tape (PTFE) to the male threaded pipe, then thread into the FNPT end and tighten with a wrench until snug. Check for leaks after press installation.
- Pressure test the assembly to confirm a tight, leak-free connection before turning the water back on.
Designed for professionals and DIYers alike, the QuickFitting 1/2 in. Press in. FNPT copper adapter delivers a dependable, code-conscious solution that simplifies complex piping runs. Choose this adapter when you need a compact, corrosion-resistant link between pressed copper tubing and standard threaded components, with the added assurance of NSF listing for potable-water safety.
