More durable than plastic caps, these provide the most protection from abrasion and impact.

Give open-ended standoffs a finished look and protect them from dirt and debris.

A thin head means these caps sit nearly flush with your surface for a clean look.

Seal tube and hose fittings to keep their straight threads protected from contaminants during fabrication and storage.

Seal T-slots, rail ends, and gaps between rails to keep out dust, debris, and other contaminants.

Half the weight of steel, this aluminum framing resists corrosion in wet environments.

The domed top allows you to firmly hold these knobs in the palm of your hand to position, tighten, and hold fixtures, equipment, and machinery. Install these knobs on a threaded stud.

A handle makes these knobs easy to turn. Tap custom threads or secure with a set screw to provide a firm grip to position, tighten, and hold fixtures, equipment, and machinery.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

Use these couplings at pressures up to 6,500 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Snap-Tite H-Shape plugs and sockets.

Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering.

These sights have a glass window.

Protect screw-together M12 connectors when not in use.

Protect Mil. Spec. connectors when not in use.

Close off unused outlets.

Mount these boxes to the outside of an enclosure to access a programmable logic controller or other networked device without opening the enclosure.

These corrosion-resistant covers can withstand rain, snow, and wet conditions without being damaged.

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Choose from flat and grooved liners.
