Merit Brass 650-08 Slip-on Pipe Flange 1/2 in 150 Psi Ss 316

Product Description

The MERIT BRASS 650-08 is a slip-on pipe flange designed for 1/2 inch pipe with a 3-1/2 inch outside diameter. Constructed from Grade 316 stainless steel, this flange offers strong corrosion resistance in demanding fluid handling and piping applications. It is rated at 150 psi and features four bolt holes spaced 2-3/8 inches across bolt hole centers, with each bolt hole measuring 5/8 inch in diameter. Plumbers, pipefitters, and industrial maintenance technicians use slip-on flanges to connect pipe sections to equipment, valves, or other flanged components by sliding the flange over the pipe end and welding it in place.

This flange is suited for residential and commercial plumbing, process piping, and industrial installations where corrosion resistance is a priority. Grade 316 stainless steel is commonly selected for environments exposed to chlorides, saltwater, or chemical media. The 150 psi pressure rating makes this flange appropriate for low-to-medium pressure piping systems. A licensed pipefitter or plumber typically handles flange installation in systems governed by applicable mechanical and plumbing codes.

Key Features

• Slip-on design for 1/2 inch pipe — slides over pipe end for field weld attachment
• Grade 316 stainless steel construction for superior corrosion resistance
• 3-1/2 inch outside diameter with circular flange profile
• Rated at 150 psi for low-to-medium pressure service
• Four bolt holes at 5/8 inch diameter, centered at 2-3/8 inches across bolt hole centers

Compatibility

Designed as an OEM-style slip-on pipe flange for 1/2 inch pipe systems requiring a 150 psi rated, 316 stainless steel flanged connection.

Installation Notes

Slip-on flanges are installed by a qualified pipefitter or welder — the flange is slid over the pipe end and secured with a fillet weld on both the face and bore. Shut down and depressurize the piping system completely before beginning any flange work. Follow applicable codes such as ASME B31.1 or B31.3 for pressure piping, and ensure proper gasket selection and bolt torque sequence are used when making up the flanged joint. Do not exceed the 150 psi pressure rating of this flange in service.
