Value Brand Cross 1" FNPT Malleable Iron Class 300

Cross fitting for four-way pipe junctions

This malleable iron cross fitting connects four pipes in a single junction. Each end features a 1-inch female NPT thread with 11 1/2 threads per inch. The Class 300 rating suits high-pressure plumbing installations. It is intended for installers who need a durable four-way connection in iron piping systems.

Behaviour under sustained pressure

Malleable iron provides consistent structural integrity when the system operates at the rated Class 300 pressure over long periods. The material resists deformation better than lower-class fittings during continuous service. Thread engagement remains reliable through thermal cycling and vibration. The fitting is designed for permanent installation in demanding environments.

Class 300 pressure rating decides fit

The Class 300 designation is the single specification that determines whether this cross matches the system design pressure. Systems requiring a lower class rating can use this fitting, but those exceeding Class 300 cannot. Buyers who need a higher pressure class must select a different fitting. Always verify the engineering specification before purchase.
