843 Products

Pipe and 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.

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.

Standard-Wall Steel Threaded Pipe Nipples and Pipe

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

Standard-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Thick-Wall Steel Threaded Pipe Nipples and Pipe

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

Standard-Wall Stainless Steel
Threaded Pipe Nipples and Pipe

Typically used with low-pressure stainless steel threaded pipe fittings.

Standard-Wall Brass Threaded Pipe Nipples and Pipe

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

Standard-Wall Aluminum
Threaded Pipe Nipples and Pipe

Typically used with low-pressure aluminum threaded pipe fittings.

Metal Tubing for Flow

Smooth-Bore Seamless Stainless Steel Tubing

This tubing has a seamless construction with no weld bead for unrestricted flow and is stronger than welded tubing.

Welded Stainless Steel Tubing

When your application does not require a smooth interior, this tubing is an economical choice.

Smooth-Bore Seamless Steel Tubing

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

General Purpose Copper Tubing

Copper tubing has good corrosion resistance and excellent heat transfer qualities.

Raw Materials

Polished Multipurpose 304 Stainless Steel

Polished to either a brushed or mirror-like finish, this material is often used to fabricate decorative enclosures and industrial workstations.

Ultra-Formable 260 Brass Round Tubes

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

Low-Carbon Steel Rectangular Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Ultra-High-Temperature Quartz Glass Tubes

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack.

Borosilicate Glass Tubes

Also called Pyrex and Schott glass, these glass tubes resist clouding and pitting and are highly chemical and heat resistant.

Clear Impact-Resistant Polycarbonate Tubes

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.

Flexible Plastic Conduit and Fittings

Flexible Plastic Conduit

Make tight bends in machine and equipment wiring.

Crush-Resistant Flexible Plastic Conduit

Thicker corrugations make this conduit more crush resistant than standard flexible plastic conduit.
