  • Four female NPT ports enable multi-direction piping
  • Malleable iron construction rated to 300 psi WOG at 150 °F
  • Meets ASTM A-197, ASTM A47, ASME B 16.3 and B 16.14 standards
  • UL Listed and FM Approved for fire-protection use
  • Class 150 rating supports 150 psi saturated steam service

1-Inch Malleable Iron Cross Coupling

This four-way cross coupling accepts 1-inch FNPT threads on every port. Black malleable iron construction meets Class 150 pressure ratings for water, oil and gas piping. The fitting is UL listed and FM approved for code-compliant installations. It suits plumbers and maintenance crews building or repairing threaded pipe networks.

300 psi WOG and 150 psi Steam Rating

Rated for 300 psi water, oil and gas at 150 degrees Fahrenheit and 150 psi saturated steam. Malleable iron handles thermal cycling without the brittleness of cast iron. No moving parts mean silent operation and zero power draw. The fitting simply contains pressure within the pipe system.

ASTM A197 and ASME B16.3 Compliance

Manufactured to ASTM A197 and ASTM A47 material standards with threads to ASME B16.3 and B16.14. Four female NPT ports allow branching in multiple directions from a single junction. Malleable iron resists cracking during installation tightening. The black finish is the standard mill surface for this alloy.

Questions about this item

How do I install the 1" FNPT cross without cracking the malleable iron?

Clean threads, apply PTFE tape or pipe dope clockwise, hand-tighten, then wrench-tighten one to two turns; over-torquing is the common mistake that fractures the fitting.

What maintenance will the Class 150 cross need after years in service?

Inspect annually for external corrosion, internal scale buildup, and thread leakage; replace if wall loss or seepage appears — no internal serviceable parts exist.

At what pressure does the 300 psi WOG rating become the limiting factor during sustained use?

Continuous water, oil or gas service above 300 psi at 150 °F exceeds the WOG limit; for saturated steam the ceiling is 150 psi.
