Midland Industries 63218 Bulkhead Fitting 2in Npt 316 Ss

Product Description

The MIDLAND INDUSTRIES 63218 is a 316 stainless steel bulkhead fitting designed to create a leak-tight, threaded pass-through connection through tank walls, enclosures, or panel assemblies. Both connections are 2-inch NPT, with a 2-11/2 thread form and a 4-1/4 inch hex for wrench engagement. The fitting measures 2-5/8 inches in length and requires a 3-inch hole for installation. It handles maximum operating pressures from 1450 to 2175 psi and an operating temperature range of -20 to 360 degrees F, making it suitable for demanding fluid and process piping applications. Licensed plumbers and pipefitters are the typical installers for this type of hardware.

This bulkhead fitting is rated for use in 150-pound class fittings applications using 316 stainless steel construction, which provides strong resistance to corrosion, chlorides, and many chemical media. Common installation scenarios include tanks, reservoirs, processing vessels, and enclosures in industrial, commercial plumbing, and process piping systems where a threaded wall penetration is required. The 2-inch NPT sizing covers a wide range of medium-to-large diameter pipe connections encountered in these environments.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC and facility piping codes. Depressurize and drain the tank or vessel completely before installing or removing this fitting. Use appropriate pipe thread sealant rated for the media and temperature range of the application. Tighten to the hex flats using a properly sized wrench - do not over-tighten, as this can crack the tank wall or damage the fitting threads.
