Galvanized hex bushing, 3/8 inch male to 1/4 inch female NPT

Value Brand

Value Brand 3/8" MNPT x 1/4" FNPT Galvanized Hex Bushing

SKU CH-8KGQ-ZATGM

Galvanised malleable-iron hex bushing reduces 3/8″ male NPT to 1/4″ female NPT for Class 150 plumbing systems

  • Galvanized coating resists corrosion in plumbing systems
  • Malleable iron construction provides strength for Class 150 service
  • 3/8 inch male to 1/4 inch female NPT adapts pipe sizes
  • Hex profile allows secure installation with standard wrenches
  • California Proposition 65 warning notes chemical hazards for safety awareness

Application & Fit

This galvanised hex bushing reduces a 3/8 inch male NPT thread to a 1/4 inch female NPT thread. It suits plumbers and maintenance crews who need to step down pipe sizes in water, air or oil lines. The Class 150 rating covers typical low-pressure residential and light-commercial systems.

Material Benefit

Malleable iron construction resists cracking under mechanical stress better than cast iron, while the galvanised coating slows corrosion in damp environments. These properties extend service life in outdoor or humid installations without requiring additional sealants beyond standard thread tape.

Capacity Limits

The fitting handles pressures up to the Class 150 designation at ambient temperatures. It is not intended for high-pressure hydraulic circuits, steam service or systems exceeding the rated class. Buyers needing larger step-down ratios or higher pressure classes should select a different fitting.

Questions about this item

Will the galvanized coating on the malleable iron bushing wear off and require replacement?

The galvanized finish protects the malleable iron body from corrosion under normal plumbing conditions. Inspect threads periodically for scale or damage; replace the fitting if the coating is breached or threads are stripped.

What pressure limit does the Class 150 rating impose during continuous service?

Class 150 designates a maximum working pressure of 150 psi for water, oil, or gas at ambient temperature. Sustained pressure above this rating risks leakage or fitting failure.

Does the fitting generate heat or noise when water runs through it all day?

A static hex bushing has no moving parts and produces no operational noise or heat. Fluid temperature and flow velocity are determined by the piping system, not the fitting itself.
