Low-Pressure Stainless Steel Unthreaded Pipe Flanges
Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line.
304 stainless steel flanges offer very good corrosion resistance, and 316 stainless steel flanges have excellent corrosion resistance.
Forged flanges have better strength than cast flanges. Socket-connect flanges have an internal stop that supports the pipe when welding and prevents the pipe from sliding all the way through.

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat. Fittings have an internal stainless steel gripping ring and rubber O-ring that create a seal when crimped. They are designed to leak if fittings have not been crimped; a colored dot marks the leak path so it's easy to spot unsealed connections. These fittings are comparable to Viega MegaPress fittings.
Fittings comply with the Uniform Plumbing Code for plumbing systems and the Uniform Mechanical Code for HVAC and refrigeration. They also meet ANSI/ASME B31 code requirements for use in pressure piping systems.
304 stainless steel fittings resist corrosion from frequent exposure to water and fuels. They are often used for water processing lines, heating and cooling systems, and fuel lines.
316 stainless steel fittings stand up to harsh environments with constant exposure to chemical solutions. They meet NSF/ANSI Standard 61 for use with drinking water, and are often found on water and chemical processing lines in corrosive environments.
Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line.

Crimping tools seal fittings in less than five seconds. These tools are cordless, so you can take them to any job. Connect the jaw or ring that matches your pipe size to these tools, then pull the trigger to crimp the fitting. The pivoting head lets you access connections from any angle.

High-Pressure Stainless Steel Unthreaded SAE Pipe Flanges
Create an access point in a high-pressure hydraulic fluid line with these flanges. They are also known as Code 61 SAE hydraulic flanges. To connect, bolt a flange with an O-ring groove surface to a flange with a flat surface of the same size. Flanges are 316 stainless steel for excellent corrosion resistance.
Socket-connect flanges weld to pipe for a strong, permanent connection. Cap flanges are also known as blind flanges.
