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.

Ultra-Corrosion-Resistant Aluminum Tubing

Commonly used in marine applications, this tubing contains magnesium for extra corrosion resistance.

Corrosion-Resistant Steel Tubing

A thin layer of zinc yellow-chromate gives this tubing extra corrosion resistance, making it an economical alternative to stainless steel.

Super-Corrosion-Resistant Nickel Tubing

Run corrosive substances through this tubing without worrying about pitting and stress cracking. It is also known as Hastelloy.

Acid-Resistant Nickel Tubing

This tubing won't degrade, even when used with harsh acids. It is also known as Monel.

High-Pressure Smooth-Bore
Seamless Titanium Tubing

Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.

Tube Fittings for Nickel Alloy Tubing

Ultra-Corrosion-Resistant Yor-Lok
Fittings for Nickel Alloy Tubing

With the best corrosion resistance of any metal fitting we offer, these Hastelloy fittings will stand up to aggressive chemicals and are resistant to pitting and stress cracking. Also known as instrumentation fittings, they include a nut with two sleeves.

Yor-Lok Fittings for Nickel Alloy Tubing

Acid-Resistant Yor-Lok
Fittings for Nickel Alloy Tubing

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.

Pipe and Pipe Fittings

Standard-Wall Copper-Nickel
Threaded Pipe Nipples and Pipe

Also called close nipples, these Schedule 40 nipples are threaded on both ends to the center.

Copper-Nickel Unthreaded Pipe

Also known as Pressure Class 200 pipe.

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 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-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 it easy to clean. Made of polypropylene, it resists organic solvents, acids, and alkalis better than CPVC pipe.

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 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.

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.

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.
