About Hose

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

Plastic Quick-Turn Tube Couplings for Air and Water

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings.

Electrical Wiring and Connecting

Power-Indicating Straight-Blade Plugs and Sockets

Visually confirm that connectors have power; they have an indicating light that is visible from any angle.

Sure-Grip Straight-Blade Plugs,
Sockets, and Receptacles

Also known as hospital-grade connectors, these have an extra-tight fit when mated to remain secure in high-vibration environments.

Power-Indicating Sure-Grip Straight-Blade Plugs

An indicating light that is visible from any angle lets you know when these plugs have power. They have an extra-tight fit when mated with a receptacle to withstand high vibration. Also known as hospital grade plugs.

Sure-Grip Straight-Blade Plugs with Fuse Holder

Add a fuse to protect equipment from current overload. When mated with a receptacle, these plugs have an extra-tight fit to remain secure in high vibration environments. They're also known as hospital grade plugs.

Status-Indicating Micro
M12 Screw-Together Connectors

Visually confirm your connector is working properly. A green light means your connector has power, while yellow means it has signal.

Status-Indicating Nano M8 Connectors

Visually check that your low-current devices with M8 connections are powered up and sending and receiving signals. These connectors illuminate green if they have power and yellow if they have signal.

Unshielded Easy-Install Crimp-On Data Connectors

Pull wires all the way through the connector face, and then use the crimper to cut and crimp wires in one step.

Unshielded Crimp-On Data Connectors

Use an Ethernet cable crimper to terminate these plugs.

Outlet Splitters

Connect multiple devices from a single outlet.

Caps for Outlets and Plugs

Cover unused electrical outlets or plug prongs to protect them from dust, dirt, liquids, and other contaminants.

Caps and Plugs

High-Temperature Tapered Plugs

Good for electroplating, paint baking, and powder-coating applications, these plugs withstand temperatures up to 570° F. All are tapered to fit a range of hole diameters.

Expandable High-Temperature Tapered Plugs

Place a plug into an opening and tighten the wing nut—the sides expand to create a seal in holes of varying diameters. Good for paint baking and powder-coating applications, these plugs withstand temperatures up to 450° F.

High-Temperature Round Plugs for NPT Pipe

These plugs withstand temperatures up to 600° F to protect internally threaded NPT connections from contaminants during electropainting, paint baking, and powder coating applications.

High-Temperature Pull-Through Round Plugs

Good for electroplating, paint baking, and powder-coating applications, these plugs withstand temperatures up to 600° F. To form a tight seal, use the smaller end of the plug to pull the larger end into a through hole.

Flanged Pull-Through Round Plugs

Designed with a flange, these plugs protect countersunk holes during anodizing, electroplating, paint baking, and powder-coating applications. All withstand temperatures up to 600° F. Use the smaller end of the plug to pull the larger end into a through hole to form a tight seal.

Miniature Pull-Through Round Plugs

Also known as mouse tails, these tiny plugs fit through-hole IDs as small as 0.022”, 0.025", or 0.03”.

Clear Locking Panel Plugs

These plugs are see-through to provide visibility and light transmission. They have wings that expand against the sides of the hole to lock them in place.

Stretchable Elastic Caps

Similar to a shower cap, these caps have an elastic band that allows them to stretch and cover a variety of shapes in a range of sizes.

Tear-Tab Caps

Push these caps onto pipe and fittings, then tear their tab to break the seal for easy removal.

Storage and Waste Containers

Dust Caps for Drums

Protect contents from dirt, dust, and other contaminants with these caps.

Dust Caps for Pails

Stretch these plastic caps over the tops of pails to keep out dust, bugs, and other debris.

Ambient-Noise Canceling Earplugs

Reduce exposure to loud background noise from nearby machinery without blocking out voices. Instead of muffling all sound like other earplugs, these soften sound to enable clear communication.
