About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

Rotating Reducing Flanges, Female Socket-Connect × Flanged

Rotating flanges have a ring that swivels for easy bolt hole alignment.

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.

Quick-Clamp High-Vacuum Fittings for Stainless Steel Tubing

For Use With:
Fittings with Gasket End: Air, Argon, Helium, Nitrogen
All Other Fittings: Air
Specifications Met: ISO 2861

Instead of a gasket, these fittings have a metal-reinforced O-ring that is designed for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases. Also known as KF, QF, and NW fittings, they are the most common type of connection in high-vacuum systems. Connect with a clamp and another quick-clamp fitting for fast, easy access to your line. To use fittings in pressure applications, use a pressure-rated ring (sold separately). Made of 304 stainless steel, these fittings have very good corrosion resistance.

Note: To complete a connection, you’ll need two quick-clamp fittings, a ring, and a clamp (all sold separately).

Valves with Shut-Off

Temperature Range: 0° to 190° F
Tubing: Use with 304/304L or 316/316L stainless steel

Valves are also known as vacuum isolation valves. They connect to a vacuum system so you can install gauges, release gases, and remove air. They operate manually and have a compact body that fits easily into tight spaces.
