How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Iron and Steel Pipe Fittings with Flanged Ends

Bolt the flanged end of these fittings to another same-size flange, pump, or valve with a gasket (sold separately) to create an access point in a pipe line. Raised-surface flanged ends only mate with other raised-surface flanged ends, and flat-surface flanged ends only mate with other flat-surface flanged ends. Use in noncorrosive environments.

Drain, Waste, and Vent ABS Pipe Flanges for Chemicals

For Use With: Sodium Hydroxide
Max. Temperature: 180° F
Specifications Met: ASTM D2661, ASTM D3311, ASTM D3965, ASTM F1498
Pipe NIpples and Pipe: Use Schedule 40 ABS Plastic
Fittings: Use Schedule 40 ABS Plastic

These Schedule 40 flanges are an economical choice for gravity-flow chemical waste systems. Flanges are ABS plastic, which has excellent strength and impact resistance and good chemical resistance. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. They have socket-connect ends that attach to unthreaded pipe or another socket-connect fitting with ABS cement (also known as solvent weld). They meet ASTM D2661, ASTM D3311, ASTM D3965, and ASTM F1498 specifications and testing requirements for material quality and product dimensions.

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

Aboveground Standard-Wall PVC Pipe Flanges for Drain, Waste, and Vent

For Use With: Water
Max. Temperature: 140° F
Specifications Met: ASTM D1784, ASTM D2665
Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
Fittings: Use Schedule 40 PVC Plastic

Also known as Schedule 40 flanges, these are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. They are PVC for good corrosion resistance. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. They have socket-connect ends that attach to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld). Flanges meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.

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

Ultra-High-Vacuum Flanges and Fittings for Stainless Steel Tubing

For Use With: Air
Temperature Range:
Flanges: -300° to 800° F
Gaskets: Not Rated
Tubing: Use with 304/304L and 316/316L stainless steel
Specifications Met:
Flanges: ASTM A240, ASTM E45, ASTM E12
Gaskets: ASTM B152-179, ASTM F68

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket (sold separately) between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets. Also known as CF, Conflat, and UHV fittings, use them in vacuum coating, heat treating, and drying applications, as well as for leak testing and analyzing gases. They’re stainless steel so they resist rusting.

Fittings with a rotating flange turn so you can easily match up the bolt holes with another flange that may be misaligned.

Bolt kits are required to make a complete connection.
