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.

Underground PVC Pipe Fittings
for Drain, Waste, and Vent

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

Underground PVC Pipe for Drain, Waste, and Vent

This pipe has thinner walls than Schedule 40 pipe, so it’s lighter in weight and has more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines.

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

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

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

Bolt two same-size flanges together with a gasket to create an access point within a line. Also known as Schedule 40 flanges, they are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Underground Snap-Lock Polyethylene
Pipe Fittings for Drain, Waste, and Vent

The snap-together design allows you to quickly connect these fittings to pipe with no cement required. Fittings are typically used in gravity-flow drainage applications.

Underground Snap-Lock Polyethylene
Pipe for Drain, Waste, and Vent

Pipe has a snap-together design that allows you to quickly connect to fittings with no cement required. It is typically used in gravity-flow drainage applications.

Cast Iron-to-PVC Pipe Adapters
for Drain, Waste, and Vent

These adapters connect PVC waste pipe to cast iron pipe without adding bulk. Instead of securing pipes together from the outside like clamp-on couplings, these flexible adapters fit into cast iron pipe to create a tight compression seal.

Gravity-Flow Plastic Pipe and Pipe Fittings for Chemical Waste

Drain, Waste, and Vent ABS
Pipe Fittings for Chemicals

These fittings are an economical option for chemical waste systems. Fittings are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Drain, Waste, and Vent ABS Pipe for Chemicals

This pipe is an economical choice for gravity-flow chemical waste systems. Pipe is ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Drain, Waste, and Vent ABS
Pipe Flanges for Chemicals

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges 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.

Gravity-Flow CPVC Pipe Fittings
for Corrosive Chemical Waste

These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances.

Gravity-Flow CPVC Pipe for
Corrosive Chemical Waste

Use this pipe in gravity-flow applications that involve highly-corrosive chemicals–it is NSF certified for use in corrosive waste systems. Pipe is made of CPVC, which has better chemical resistance than ABS plastic to stand up to acids and other harsh substances.

Gravity-Flow Polypropylene Pipe
Fittings for Corrosive Chemical Waste

Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies.

Gravity-Flow Polypropylene Pipe
for Corrosive Chemical Waste

Made of polypropylene, this gravity-flow pipe stands up to tough organic solvents, such as acetone, that would dissolve CPVC pipe. You can also use it for lines with highly corrosive acids, such as hydrochloric acid, and alkalies.

Low-Pressure Clamp-On Connectors

Low-Pressure Clamp-On Connectors
for Drain, Waste, and Vent

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

Cut-to-Length Low-Pressure Clamp-On
Connectors for Drain, Waste, and Vent

Connect two pipes that are up to 100 feet apart—cut the connector to the length you need and attach a clamp to each end.

Low-Pressure Clamp-On Connectors for Water

Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly.

Low-Pressure Clamp-On
Connectors for Chemical Waste

With an FEP sleeve and PTFE sealing tape, these connectors withstand chemicals better than rubber connectors. Use them for joining low-pressure chemical waste drainpipe and fittings or transitioning between different chemical piping.

Drain, Waste, and Vent Iron Pipe and Pipe Fittings

Drain, Waste, and Vent Iron Pipe Fittings

Also known as no-hub pipe fittings and soil pipe fittings, these fittings are for use in gravity-flow applications both above and below ground.

Drain, Waste, and Vent Iron Pipe

Use this pipe in gravity-flow applications both above and below ground.

Clamp-On Expansion Joints for Drain, Waste, and Vent

Clamp-On Expansion Joints
for Drain, Waste, and Vent

These joints are designed for vertical use in drain, waste, and vent systems.

Plumbing Fixtures and Drains

Air Admittance Valves

No need to vent your plumbing to the outdoors—these valves allow air into your drain, waste, and vent system.

Floor Drain Cleanouts

Create an access point to inspect and clean a floor drain pipeline.

Neutralization Tanks

For safe and legal disposal of corrosive chemicals, these tanks neutralize acid waste before it drains into sewer systems.

Sink Drains

Empty liquids from sinks into sewer lines.
