Midland Industries 64400 3 Inch Fpt Galvanized Iron Cross Fitting

Product Description

The MIDLAND INDUSTRIES 64400 is a four-way cross pipe fitting designed for use in threaded piping systems that require a single inline connection point with two lateral branches. Constructed from malleable iron with a galvanized finish, this fitting accepts 3-inch female pipe thread (FPT) connections on all four ports. It is rated to 150 psi and handles temperatures from -20 to 350 degrees F, making it suitable for water, air, and similar low-pressure fluid distribution applications. The 3-8 thread specification and compliance with ANSI B16.3 dimensional standards confirm it as a standard-grade commercial fitting. Plumbers and pipefitters install this type of fitting during rough-in and distribution work on larger-diameter galvanized systems.

The 64400 is used in residential and commercial plumbing, industrial piping, and mechanical room distribution lines where a 3-inch galvanized threaded cross configuration is required. Its four-port layout allows a single fitting to serve a main run while supplying two perpendicular branch lines simultaneously, reducing the number of unions and couplings needed at the junction. This fitting is well-suited for overhead or wall-mounted runs where space at the junction allows for the full cross body footprint.

Key Features

• Four 3-inch FPT ports for full four-way threaded connection
• Malleable iron construction with galvanized finish for corrosion resistance
• 150 psi pressure rating for standard low-pressure systems
• Temperature range: -20 to 350 degrees F
• Conforms to ANSI B16.3 dimensional standards
• 3-8 thread specification for consistent fit with standard pipe threads
• 3.06-inch centre-to-end dimension for layout planning

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch galvanized malleable iron threaded piping systems rated at 150 psi, conforming to ANSI B16.3 standards.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on threaded galvanized pipe systems. Shut off and depressurize the line completely before removing any existing fittings or threading in the new cross. Apply appropriate thread sealant or PTFE tape to all male threads before assembly, and tighten to a secure fit using pipe wrenches without over-torquing the malleable iron body. Work must comply with applicable local plumbing codes and standards such as the IPC or IFGC where relevant.
