Merit Brass 635-08 Threaded Pipe Flange 316 Ss 1/2 in

Product Description

The MERIT BRASS 635-08 is a threaded pipe flange machined from Grade 316 stainless steel, designed to connect 0.5-inch nominal pipe to flanged equipment, valves, or mating flanges in piping systems. It features a 3.5-inch outside diameter, a 150 psi pressure rating, and a four-bolt-hole pattern on a 2.375-inch bolt circle. The threaded end accepts standard NPT pipe, making field assembly straightforward without welding. Plumbers, pipefitters, and industrial maintenance technicians install this type of flange in corrosive-fluid and high-moisture environments where Grade 316 stainless provides superior resistance to chlorides and chemical exposure.

This flange is suited for use in residential and commercial plumbing, marine piping, food-service lines, and chemical-handling systems where stainless construction and threaded connections are required. The 150-class pressure rating aligns with standard low-pressure service applications. Each bolt hole measures 0.625 inches in diameter, accommodating standard flange fastener hardware. It is sold as a single unit and is a practical choice for maintenance, repair, and new installation work on 0.5-inch nominal pipe runs.

Key Features

• Grade 316 stainless steel construction for corrosion resistance in chloride and chemical environments
• Threaded connection type accepts standard NPT pipe — no welding required for assembly
• 150 psi pressure rating suitable for standard low-pressure piping service
• Four-bolt-hole pattern on a 2.375-inch bolt circle for secure flanged joint assembly
• 3.5-inch outside diameter with 0.625-inch bolt holes sized for standard flange hardware
• Circular shape with uniform bolt hole spacing for proper load distribution at the joint

Compatibility

Designed as an OEM-style replacement and new-installation threaded pipe flange for 0.5-inch nominal pipe systems operating at 150-class pressure ratings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and ASME B16.5 or B16.15 standards. Shut off and depressurize the pipe system completely before removing or installing any flange. Apply appropriate thread sealant or PTFE tape to the NPT threads before making up the threaded connection. Torque flange bolts evenly in a cross pattern to ensure uniform gasket compression and a leak-free joint.
