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.

Harsh Environment High-Current Distribution Bars

Protect connections against corrosion.These bars are tin-plated copper and have stainless steel terminals.

Modular Distribution Bars

Build your own distribution system by adding terminal blocks to these bars.

Tubing and Tube Fittings

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.

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.

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.

Metal Pipe and Pipe Fittings

Medium-Pressure Pipe Fittings
for Joining Dissimilar Metals

Use these unions to connect different metals in a piping or plumbing system. They have a gasket with a plastic sleeve that inhibits destructive corrosion.

Copper-Nickel Threaded Pipe Fittings

These fittings have excellent resistance to stress cracking and have better corrosion resistance than most stainless steel alloys.

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 Butt-Weld Pipe Fittings

Also known as Pressure Class 200 fittings.

Copper-Nickel Unthreaded Pipe

Also known as Pressure Class 200 pipe.

Rivets

Copper Domed Head Blind Rivets

Copper rivets are electrically conductive and have good corrosion resistance.

Copper Flat Head Solid Rivets

Copper rivets are electrically conductive and have good corrosion resistance.

Copper Domed Head Solid Rivets

Copper rivets are electrically conductive and have good corrosion resistance.

Solid Rivets with Washer for Soft Material

The washer creates a large holding surface on the back of the material. Also known as belt rivets, these are used for fastening conveyor belts or leather. A special setting tool and a hammer are required for installation.

Bonding and Grounding

Grounding Rod Clamps

Connect bare-copper ground wire to grounding rods.

Grounding Straps

Straps fit around pipes and grounding rods.

Grounding Bars

Mount these bars wherever you need to create a central grounding point.

Grounding Blocks

Connect multiple ground wires in tight spaces such as cabinets and enclosures.

Grounding Braid

More flexible than wire and ribbon, this braid is suitable for use in tight spaces.

Grounding Wire

Ground your electrical system.

Grounding Ribbon

The smooth, flat design provides more surface area contact than wire or braid.

EMI-Reducing Grounding Ribbon

Low resistance at radio frequencies reduces electromagnetic interference (EMI). It has a smooth, flat design that provides more surface area contact than wire or braid.

Lightning Protection

Protect electrical systems from lightning strikes on structures up to seventy-five feet tall.

Bend-and-Stay Positioning Arms

Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.

Wire Rope End Fittings

Wire Rope Compression Sleeves—For Lifting

These compression sleeves are designed to meet lifting specifications.

Wire Rope Stops—Not for Lifting

Electric Bird Repellent Strips

This electrified system delivers a mild, pulsing shock to deter birds. Install up to 1000 ft. of flexible plastic shock strip on roof edges, window sills, gutters, and ledges and connect to the solar power supply.

3D Printer Extruder Heating Elements

Replace damaged heating elements in your 3D printer, or switch them out to print at a faster speed or higher temperature.
