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.

Temperature Range: 32° to 200° F

Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61 or EN 1057.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Socket-Connect Fittings for Stainless Steel Tubing

For Use With: Air, Hydraulic Fluid, Water
Tubing: Use with seamless or welded 304 or 316 stainless steel that meets ASTM A269

Easier to weld than butt-weld fittings, these fittings don’t need to align perfectly to tubing. Insert tubing into the socket end and weld to create a permanent, leak-tight connection. Fittings are 316 stainless steel for excellent corrosion resistance.

Drain, Waste, and Vent ABS Pipe Fittings 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
Flanges: Use Schedule 40 ABS Plastic

These Schedule 40 fittings are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance. Fittings meet ASTM D2661, ASTM D3311, ASTM D3965, and ASTM F1498 specifications and testing requirements for material quality and product dimensions.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with ABS cement (also known as solvent weld).

Warning: Never use plastic pipe fittings 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.

Gravity-Flow CPVC Pipe Fittings for Corrosive Chemical Waste

For Use With: Hydrochloric Acid, Nitric Acid, Salt Water, Sulfuric Acid
Temperature Range: 40° to 200° F
Specifications Met: ASTM F2618, IAPMO Certified, NSF/ANSI 14, UL 94 V-0

Made of CPVC, these fittings have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances. They meet NSF/ANSI 14 requirements for use in corrosive waste gravity-flow systems. Fittings are comparable to Corzan. They meet UL 94 V-0 for flame retardance and ASTM F2618 specifications and testing requirements for material quality. They are IAPMO certified to comply with the International Association for Plumbing and Mechanical Officials product performance standards and the Uniform Plumbing Code (UPC) for installation and repair of plumbing systems.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a CPVC primer and cement (also known as solvent weld).

270° bend fittings are also known as P-traps. They separate into three pieces, so you can access your line.
