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 meet ANSI/ASME B31 code requirements for use in pressure piping systems.

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.

Also known as Pressure Class 150 flanges, these are designed for low-pressure pipe applications. 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 within a line.

304 stainless steel flanges have very good corrosion resistance. 316 stainless steel flanges have excellent corrosion resistance. Alloy 20 stainless steel flanges have the best corrosion resistance of all the stainless steel flanges we offer. Alloy 20 stainless steel is also known as Carpenter 20 and resists cracking from stress and corrosion.

Forged flanges have better strength than cast flanges. They are also called ANSI flanges. Cast flanges are also called MSS 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. Flanges are for use with low-pressure applications in noncorrosive environments.

Butt-weld flanges are also known as weld-neck flanges. The flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld.

Slip-on weld flanges have no internal stop. Slide a pipe through the flange and weld on both sides.

Socket-connect flanges have an internal stop that supports the pipe when welding and prevents the pipe from sliding all the way through.

Stub-end flanges are also known as lap-joint flanges. Use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting.

Cap flanges are also known as blind flanges.

Use these flanges for low-pressure applications in noncorrosive environments. Bolt two flanges of the same size together with a gasket (sold separately) to create an access point within a line.

Reducing flanges allow you to transition your system to a smaller pipe size; attach to a flange with a larger pipe size but with the same flange dimensions.

Also known as Pressure Class 125 flanges, these are for use in low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are aluminum, which is lightweight with good corrosion resistance.

Reducing flanges allow you to transition your system to a smaller pipe size; attach to a flange with a larger pipe size but with the same flange dimensions.

Also known as Pressure Class 150 flanges, these are designed for low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges have good corrosion resistance. To adhere to safety standards for drinking water systems, use flanges that meet NSF/ANSI 61.

Bolt these flanges to equipment or to another same-size, flat-surface flange with a gasket (sold separately). They have good corrosion resistance.

Socket-connect flanges braze onto unthreaded pipe with a brazing ring (sold separately) for a strong, leak-resistant connection. They are also known as Silbraze flanges.

Also known as Pressure Class 150 flanges, these flanges have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They meet NSF/ANSI 61 for drinking water. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. All are PVC, which has good corrosion resistance. They meet ASTM D1784 specifications and testing requirements for material quality.

Warning: Never use plastic pipe flanges and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.
