Merit Brass 450-48 Slip on Pipe Flange 3 in 150 Psi 304 Ss

Product Description

The MERIT BRASS 450-48 is a slip-on pipe flange machined from Grade 304 stainless steel, designed for use on 3-inch nominal pipe with a 7.5-inch outside diameter. Rated at 150 psi, this flange accepts a standard slip-on connection and is secured with four bolts on 6-inch bolt hole centers. Each bolt hole measures 0.75 inches in diameter. The circular flange profile and corrosion-resistant 304 stainless construction make it suitable for process piping, plumbing, and industrial fluid systems where sanitary or corrosion-resistant materials are required. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This slip-on flange is used in residential and commercial piping systems where a flanged connection is needed on 3-inch pipe. Typical applications include water supply lines, process fluid systems, and industrial installations where Grade 304 stainless steel is specified for corrosion resistance. The 150 psi pressure rating makes it appropriate for standard-pressure service in piping assemblies that require a bolted flange joint at terminations, equipment connections, or inline service points.

Key Features

• Slip-on connection style for straightforward field installation on 3-inch nominal pipe
• Grade 304 stainless steel construction for corrosion resistance in wet and process environments
• 150 psi pressure rating suitable for standard-pressure piping service
• 7.5-inch outside diameter with four bolt holes on 6-inch bolt hole centers
• 0.75-inch bolt hole diameter for standard flange bolt hardware
• Circular profile consistent with standard raised-face or flat-face flange assemblies

Compatibility

Designed as an OEM-style replacement or new-installation slip-on flange for 3-inch nominal pipe systems rated to 150 psi Class, using Grade 304 stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable piping codes such as the IPC or ASME B16.5 standards. Depressurize and drain the piping system fully before removing or installing any flange fitting. Slip the flange over the pipe end to the correct setback distance before tack welding or securing, and verify bolt hole alignment with the mating flange before final assembly. Use appropriate gasket material rated for the service fluid and pressure when completing the bolted joint.
