Milwaukee Valve UP548T 1 in Bronze Spring Check Valve
A 1-inch bronze spring check valve with FNPT connections, rated for 250 psi water pressure at 150 degrees F and a cracking pressure of .750 to 1.000 psi
- TypeOther
- Bronze construction resists corrosion for long service life
- Inline spring design ensures reliable flow control
- Rated to 250 psi at 150°F for demanding applications
- Operates from -20°F to 353°F across temperature extremes
- 1" FNPT connections fit standard piping systems
Purpose and fit
This bronze spring check valve installs inline on a one‑inch FNPT line to prevent backflow in plumbing and hydronic systems. The low‑lead bronze body and bronze seat suit potable‑water and general‑service piping. Horizontal mounting is required, so vertical runs cannot use this valve.
Pressure and temperature envelope
The valve opens at a cracking pressure between .750 and 1.000 psi and holds up to 250 psi water pressure at 150 Degrees F. Maximum service temperature is 353 Degrees F and minimum is -20 Degrees F, while steam service is not rated. Operating outside these limits will cause leakage or damage.
Capacity headroom
One‑inch piping and the bronze spring mechanism handle typical residential and light‑commercial flow rates without restriction. Systems that demand higher cracking pressures, vertical installation or steam service will exceed the valve’s design envelope and need a different check valve.

Questions about this item
Should I choose the 1-inch threaded version or look for a different size?
This valve is supplied in a 1-inch FNPT x FNPT connection; select it when your piping matches that size and threading.
What does the 0.750 to 1.000 psi cracking pressure mean once installed?
The spring opens when flow reaches roughly three-quarters to one psi, so very low head pressure will still allow water through.
How does the FNPT connection limit the pressure I can run?
The bronze body is rated for 250 psi at 150 °F, and the FNPT threads seal within that same pressure envelope.
