Galvanized malleable iron tee fitting with three FNPT ports

Value Brand

Value Brand 1-1/4" FNPT Galvanized Tee

SKU CH-X4D1-R0TNS

Galvanised malleable-iron tee with 1-1/4 in FNPT threads, rated 1500 psi WOG and 300 psi steam, meeting ASME B 16.3 and B 16.4 standards

  • Galvanized malleable iron resists corrosion in water lines
  • Class 300 rating handles 1500 psi at 150 °F WOG
  • FNPT threads seal directly to male NPT pipe ends
  • Meets ASME B 16.3 and B 16.4 plus ASTM A 197 and A 47 standards
  • FM Approved and UL Listed for fire-protection and safety compliance

Galvanised Tee for 1-1/4 in Pipe

This galvanised malleable iron tee connects three sections of 1-1/4 inch pipe using FNPT threads. It meets ASME B 16.3 and B 16.4 standards along with ASTM A-197 and ASTM A47 specifications. The fitting is FM Approved and UL Listed for compliant installations. It suits plumbing professionals and maintenance teams requiring a Class 300 branch connection.

Pressure Rating and Operating Limits

The tee handles a maximum pressure of 1500 psi at 150 degrees F WOG and a saturated steam pressure of 300 psi. Galvanised coating protects the iron body from corrosion in water, oil and gas lines. No moving parts or electrical components mean silent operation and zero power draw. The Class 300 construction maintains integrity under normal system pressures.

Installation Requirements and System Fit

FNPT threads require compatible male fittings and appropriate thread sealant for leak-free joints. The tee adds a single branch point without needing extra couplings or adapters. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm. Confirm local code acceptance for galvanised malleable iron before specifying.

Questions about this item

How do I install the 1-1/4" FNPT galvanized tee and which step do people often get wrong?

Thread the tee onto male NPT pipe ends using PTFE tape or pipe dope on the male threads only; the common mistake is also coating the female threads, which can cause over-tightening and cracked iron.

What maintenance or replacement will the galvanized malleable iron tee need later?

Inspect the galvanized coating periodically for white rust or red rust; if the coating is breached and the underlying iron corrodes, replace the tee because the material cannot be re-galvanised in place.

What is the first pressure limit reached under sustained hot-water use at 150 °F?

The 1500 psi WOG rating at 150 °F is the governing limit; the separate 300 psi saturated-steam rating only applies when steam is present.
