Pipe, Tubing, Hose, and Fittings

Metal Pipe and Pipe Fittings

Use to convey air, water, oil, steam, hydraulic fluid, and natural gas.

Plastic Pipe and Pipe Fittings

testString

Plastic pipe and pipe fittings are lighter in weight than metal pipe and pipe fittings. They are typically for low- to medium-pressure applications up to 1,000 psi.

Manifolds

Also known as headers, manifolds allow you to distribute air or fluid to multiple locations from a single supply source.

Junction Blocks

default

Use junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air or fluid to flow straight through the block.

Hose and Hose Fittings

Tubing and Tube Fittings

Fasteners

Thread Adapters

Thread Adapters

Adapters connect two female threads, two male threads, or a male thread and a female thread.

Easy-to-Install Thread-Locking
Inserts for Metal

Easy-to-Install Thread-Locking Inserts for Metal

Also known as E-Z Lok inserts, these inserts use adhesive to keep them in place. Install with a standard tap.

Key-Locking Inserts for Soft Metal

Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. Install with a standard tap.

Tube-End Weld Nuts

About half the strength of medium-strength steel coupling nuts, these metric nuts are for light duty fastening applications.

Left-Hand Threaded
Tube-End Weld Nuts

Use these tube-end weld nuts with left-hand threaded fasteners.

Threaded Rods and Studs

Other Adapters

Flow-Control Orifices

testString

Use these orifices with water, oil, and inert gas.

Grease Fitting Adapters

Grease Fitting Adapters

When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.

Pressure Test Fittings

Check pressure without permanently installing a gauge.

Bayonet-Style
Thermocouple Adapters

Attach thermocouple probes with a bayonet connection to a threaded connection.
