Low-Pressure Stainless Steel Threaded Pipe Fittings
Use these fittings in a low-pressure pipe line.
Fittings that meet ANSI/MSS SP-114 adhere to high-quality standards for heat treating, material thickness, and marking. 304 stainless steel fittings have very good corrosion resistance.

- For Use With: Air, Natural Gas, Oil, Steam, Water
- Class: 150
- Fabrication: Heat Treated
- Specifications Met:
NPT: ANSI/MSS SP-114, ASTM A351
BSPP and BSPT: ANSI/MSS SP-114 - Pipe Nipples and Pipe: Use Schedule 40 stainless steel
- Flanges: Use Class 150 stainless steel

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.

Quick-Clamp High-Vacuum Fittings for Stainless Steel Tubing
- For Use With:
Fittings with Gasket End: Air, Argon, Helium, Nitrogen
All Other Fittings: Air - Temperature Range: 0° to 300° F
- Tubing: Use with 304/304L or 316/316L stainless steel
- Specifications Met: ISO 2861
Instead of a gasket, these fittings have a special 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).
304 stainless steel 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).
