- Galvanised malleable iron resists corrosion for long service life
- Class 150 rating handles 300 psi at 150 °F for demanding systems
- ANSI B 1.20.1 compliant threads ensure leak-free connections
- Hex profile allows quick installation with standard wrenches
- 2-1/2 in MNPT to 1/2 in FNPT reduces pipe size in one fitting
Galvanized Hex Bushing 2-1/2" x 1/2
This galvanized malleable iron bushing reduces a 2-1/2 inch male NPT connection down to a 1/2 inch female NPT port. It is rated Class 150 for water, oil and gas service up to 300 psi at 150 degrees Fahrenheit and meets ANSI B1.20.1 threading standards.
Simple Threaded Installation
The hex body allows a standard pipe wrench to apply torque without damaging the fitting. Clean male threads, apply suitable sealant and tighten to the recommended engagement; over-tightening can crack the malleable iron casting or strip the tapered threads.
Pressure Headroom and Limits
The fitting handles saturated steam at 150 psi and operates from -20 to 150 degrees Fahrenheit. It is not suited for pressures above 300 psi WOG or temperatures beyond the rated ceiling, so high-pressure hydraulic or superheated steam systems require a heavier class fitting.

Questions about this item
How do I verify the bushing is working correctly after installation?
After threading the 2-1/2" MNPT x 1/2" FNPT bushing, pressurise the system up to 300 psi at 150 °F and check for leaks; the galvanized malleable iron meets ANSI B 1.20.1 so a tight, drip-free joint confirms it is working.
What comes in the box and do I need any extra parts?
The box contains the single galvanized hex bushing; you must supply pipe thread sealant or tape and the mating 2-1/2" female and 1/2" male NPT pipes or fittings separately.
Which version of the 511-993BC should I choose for my pressure and temperature needs?
This Class 150 fitting handles 300 psi WOG at 150 °F and 150 psi saturated steam from -20 °F to 150 °F; select it only if your system stays within those limits.
