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.

Standard-Wall Stainless Steel
Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure stainless steel unthreaded pipe fittings.

Thin-Wall Stainless Steel
Unthreaded Pipe Nipples and Pipe

Typically used with thin-wall stainless steel unthreaded pipe fittings.

Thick-Wall Stainless Steel Unthreaded Pipe

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

Extra-Thick-Wall Stainless Steel Unthreaded Pipe

Typically used with extreme-pressure stainless steel unthreaded pipe fittings.

Iron and Steel Pipe and Pipe Fittings

Standard-Wall Steel Unthreaded
Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

Thick-Wall Steel Unthreaded Pipe Nipples and Pipe

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

Super-Thick-Wall Steel Unthreaded Pipe

Typically used with extreme-pressure iron and steel unthreaded pipe fittings. Pipe is also known as Schedule XXH .

Standard-Wall Grooved-End
Steel Pipe Nipples and Pipe

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

Drain, Waste, and Vent Iron Pipe

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

Standard-Wall Brass Unthreaded Pipe

Typically used with brass and bronze unthreaded pipe fittings.

Aluminum Pipe and Pipe Fittings

Standard-Wall Aluminum
Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall aluminum unthreaded pipe fittings.

Thin-Wall Aluminum Unthreaded
Pipe Nipples and Pipe

Typically used with thin-wall aluminum unthreaded pipe fittings.

Thick-Wall Aluminum Unthreaded
Pipe Nipples and Pipe

Typically used with thick-wall aluminum unthreaded pipe fittings.

Aluminum Quick-Connect Pipe for Compressed Air

Build a compressed air system in half the time it would take to build a copper or steel system.

Copper-Nickel Unthreaded Pipe

Also known as Pressure Class 200 pipe.

Plastic Pipe and Pipe Fittings for Water

Thick-Wall Plastic Pipe for Water

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Clear-View Thick-Wall Plastic Pipe for Water

See what’s flowing through your line with this clear pipe. Since it’s Schedule 80, this pipe has thicker, stronger walls than standard-wall pipe, so you can use it for heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

Standard-Wall Plastic Pipe for Water

Connect this pipe to standard-wall plastic pipe fittings for a variety of residential and commercial low-pressure plumbing and water supply applications.

Clear-View Standard-Wall Plastic Pipe for Water

See inside your line with this clear pipe, which works in a variety of residential and commercial low-pressure plumbing and water supply applications.

Semi-Flexible Plastic Pipe for Water

Connect to barbed plastic pipe fittings with a clamp. Pipe isn't as bendable as soft tubing, but can still bend around objects, resulting in fewer connection points in your line. Fewer connection points not only shortens installation time, but also allows for smoother flow through the line.

CPVC Pipe for Hot Water

Connect to CPVC pipe fittings for use in high-temperature plumbing and water supply applications up to 170° or 200° F.

UV-Resistant Thick-Wall PVC Pipe for Water

With thicker, stronger walls than standard-wall pipe, this Schedule 80 pipe can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Use for pressures up to 550 psi. Suitable for outdoor environments, it contains an additive that protects against the damaging effects of ultraviolet light. Connect to UV-resistant PVC pipe fittings.

UV-Resistant Standard-Wall PVC Pipe for Water

This Schedule 40 pipe is typically used in low-pressure residential and commercial plumbing and water supply applications. It can handle pressures up to 300 psi. Suitable for outdoor environments, it contains an additive that protects against the damaging effects of ultraviolet light. Connect to UV-resistant PVC pipe fittings.

Plastic Pipe and Pipe Fittings for Chemicals

UV-Resistant Polypropylene Pipe for Chemicals

This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand acids, solvents, and other harsh substances.

High-Temperature PTFE Pipe
Nipples and Pipe for Chemicals

This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It is commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

Easy-Access CPVC Pipe for Chemicals

Also known as Victaulic pipe, this pipe has grooved ends that connect to fittings and flanges with a clamp, so you can access your line for routine maintenance. It is CPVC, which has excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances.

Flame-Retardant PVDF Pipe
Nipples and Pipe for Chemicals

Pipe meets UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. It is made of PVDF, which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances.

High-Purity Polypropylene
Pipe for Corrosive Chemicals

The inside of this pipe won’t leach contaminants into your line or accumulate particles—it’s polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, it resists organic solvents, acids, and alkalis better than CPVC pipe.

Fiberglass Pipe for Corrosive Chemicals

With excellent corrosion resistance, this pipe can handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. Layers of fiberglass give this pipe better strength and durability than any of our other pipe for chemicals.

High-Purity PVDF Pipe for Corrosive Chemicals

Made of PVDF that’s finished to a 12 Ra smoothness, this pipe handles some of the harshest chemicals without leaching contaminants into your line.

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.

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
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.

Plastic Pipe and Pipe Fittings for Drain, Waste, and Vent

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.

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.
