Brass Reducing Nipple 10 Pack

This pack contains ten brass reducing nipples built for plumbing connections. Each nipple joins a 1/2 inch male NPT thread to a 3/8 inch male NPT thread. The Class 150 rating indicates the pressure class for standard service. Brass construction resists corrosion in water supply lines.

Hex Reducing Nipple Upgrade

These hex reducing nipples replace worn or mismatched threaded fittings in existing piping. The jump is worth it when a secure transition between 1/2 inch and 3/8 inch NPT sizes is required. Hardened steel material adds durability for repeated assembly and disassembly. Ten pieces provide enough stock for multiple repair points.

California Proposition 65 Compliance Check

This product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. Verify local regulations before installing in potable water systems. Confirm that both 1/2 inch and 3/8 inch male NPT threads match your existing fittings. Ensure Class 150 pressure rating suits the intended application.

Questions about this item

What thread sizes does the 1/2" x 3/8" brass reducing nipple connect?

It joins a 1/2 inch male NPT end with a 3/8 inch male NPT end, both rated Class 150 for standard plumbing pressure.

How do you install these hex reducing nipples without damaging the brass threads?

Apply thread sealant to the NPT threads, hand-tighten, then use a wrench on the hex flats for one to two extra turns — over-tightening cracks the fitting.

When should the brass nipples be inspected or replaced in a water system?

Check for green corrosion or leaks at the joints annually; replace any nipple showing dezincification or cracked threads to maintain a Class 150 seal.
