Value Brand

Value Brand 3/4" x 1/4" FNPT Galvanized Reducer 5P933

SKU CH-XRY6-1FRGV

Galvanised malleable iron reducing coupling connects 3/4 inch and 1/4 inch female NPT threads for Class 150 plumbing systems

  • Reduces pipe size with 3/4 in to 1/4 in FNPT connection
  • Galvanized malleable iron resists corrosion for long service life
  • Class 150 pressure rating suits standard plumbing systems
  • NPT threads ensure reliable seal without extra sealant
  • California Proposition 65 warning informs safe handling practices

Reducing Coupling for Pipe Size Transition

This galvanized malleable iron reducing coupling connects a 3/4 inch female NPT thread to a 1/4 inch female NPT thread. It is rated for Class 150 service in plumbing and piping systems. The fitting is new and supplied under the ZORO SELECT brand for general fluid handling.

Behaviour Under Continuous Pressure

The Class 150 rating defines the pressure envelope the coupling sustains during extended operation rather than brief test spikes. Galvanized coating resists corrosion that would degrade sealing surfaces over long periods. Malleable iron construction absorbs vibration and thermal cycling without cracking under sustained load.

NPT Thread Limits and Regulatory Note

National Pipe Taper threads seal by metal-to-metal interference, so proper engagement and sealant are essential to prevent leakage at the rated class. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm. No additional restrictions on sale apply beyond this disclosure.

Questions about this item

How much heat does the 3/4" x 1/4" galvanized reducer generate when water runs through it all day?

The fitting is a passive malleable iron component with no moving parts, so it produces no heat of its own during continuous water flow.

What pipe threads must I already have to connect this 3/4" NPT female by 1/4" NPT female reducer?

You need existing piping with 3/4-inch NPT male threads on one side and 1/4-inch NPT male threads on the other to screw directly into the reducer.

Will the Class 150 malleable iron reducer thread onto older galvanized pipe that has 14 and 18 threads per inch?

Yes, the reducer uses standard NPT threads — 14 TPI for the 3/4-inch end and 18 TPI for the 1/4-inch end — matching legacy galvanized pipe of those sizes.
