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.

Soft Plastic Tubing for Food, Beverage, and Dairy

The industry standard for general purpose food, beverage, and dairy applications, this tubing meets NSF/ANSI Standard 51 for food contact.

Semi-Flexible Hard Plastic Tubing
for Food, Beverage, and Dairy

Strong, yet pliable, this tubing is good for gradual bends and can handle repeated flexing.

Cleaned and Bagged High-Purity Hard Plastic Tubing

Designed for high-purity applications, this hard tubing is cleaned and bagged to prevent dirt and moisture from contaminating the inside. It is free of plasticizers like DEHP, so it won’t impart tastes or odors to the fluid running through it.

Firm Plastic and Rubber Tubing for Drinking Water

Tubing meets NSF/ANSI Standard 61 for drinking water.

Hard Plastic Tubing for Drinking Water

This tubing has hard walls like copper tubing, but is lighter in weight and easier to install. It connects to fittings with no heat or soldering required. Tubing meets NSF/ANSI Standard 61 for drinking water.

Copper Tubing for Drinking Water

Medium-Pressure Copper Tubing for Drinking Water

This Type L tubing has thicker walls than Type M tubing. It withstands pressures up to 1,500 psi.

High-Pressure Copper Tubing for Drinking Water

This Type K tubing has the thickest walls of all our copper tubing for drinking water. It withstands pressures up to 1,900 psi.

Low-Pressure Copper Tubing for Drinking Water

This Type M tubing has the thinnest walls of all our copper tubing for drinking water. It withstands pressures up to 980 psi.

Tube Fittings for Plastic and Rubber Tubing

Push-to-Connect Fittings for Plastic
Tubing—Food and Beverage

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

High-Temperature Compression
Tube Fittings for Food and Beverage

Made of PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F.

Brass Push-to-Connect Fittings for Plastic
Tubing—Food, Beverage, and Dairy

Made of brass, these fittings withstand frequent washdowns in food-processing applications. They also adhere to NSF/ANSI safety standards, so they’re safe to use with food, beverages, and dairy.

Quick-Clamp Fittings for Dairy

Push-to-Connect Tube Fittings for Drinking Water

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

Push-to-Connect Tube Fittings for Hot Drinking Water

Fittings can withstand temperatures up to 200° F.

Barbed Tube Fittings for Drinking Water

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.

Socket-Connect Fittings for
Plastic Tubing—Drinking Water

Use these nuts with brass compression fittings to create a seal on plastic tubing. They meet NSF/ANSI 61 for use with drinking water.

Tube Fittings for Metal Tubing

Push-to-Connect Fittings for
Stainless Steel-to-Plastic Tubing

Connect stainless steel tubing on one end and plastic tubing on the other end.

Push-to-Connect Fittings for Stainless Steel Tubing

Solder-Connect Fittings for Copper Tubing

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Cleaned and Bagged Solder-Connect
Fittings for Copper Tubing

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

Press-Connect Fittings for Copper Tubing

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

Brass Push-to-Connect Fittings for Copper Tubing

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

Plastic Push-to-Connect Fittings for Copper Tubing

Made of plastic, these fittings are lightweight compared to our brass push-to-connect fittings.

Pipe and Pipe Fittings

Low-Pressure Press-Connect Stainless
Steel Unthreaded Pipe Fittings

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

High-Pressure Brass Threaded Pipe
Nipples and Pipe for Drinking Water

Typically used with high-pressure brass and bronze threaded pipe fittings.

Standard-Wall Brass Threaded Pipe Nipples and Pipe

Typically used with low-pressure brass and bronze threaded pipe fittings.

Standard-Wall Plastic Pipe for Water

Connect this pipe to standard-wall plastic pipe fittings in low- to medium-pressure applications up to 810 psi. It is typically used in residential and commercial plumbing and water supply applications.

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.

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.

Wet-Food and Beverage Hose

The PVC construction means this hose won’t impart tastes or odors on your product. Use with juice, milk, meat, poultry, and syrup.
