Brass Reducing Coupling 3/4 to 1/4

This brass reducing coupling connects a 3/4 inch female NPT thread to a 1/4 inch female threaded port. It is designed for plumbing installations that require a straight transition between two different pipe sizes. The fitting suits installers joining dissimilar diameters in water or air lines.

200 psi Maximum Operating Pressure

The coupling is rated for a maximum operating pressure of 200 psi. This single pressure limit determines whether the fitting is appropriate for the intended system. Verify that the working pressure of your application does not exceed this value before installation.

California Proposition 65 Notice

The product carries a California Proposition 65 warning for exposure to chemicals known to cause cancer and birth defects or other reproductive harm. This regulatory notice informs buyers of the potential hazard but does not alter the mechanical function of the coupling. No additional accessories or software are included with this fitting.

Questions about this item

What does the 200 psi rating mean when the coupling is installed in a plumbing system?

It indicates the maximum operating pressure the brass reducing coupling can safely handle in service.

How does the Female NPT thread standard affect what pipe or fitting can connect to the 3/4 in and 1/4 in ends?

Both ends use tapered National Pipe Threads that seal when tightened, so matching male NPT fittings are required for a leak-free joint.

What clearance and tool access are needed to thread this straight brass coupling into place?

The straight body requires enough space to turn a wrench on the hexagonal flats of each end during installation.
