About O-Rings

Push-In Pipe and Tubing Grommets

Press these flexible grommets into holes and their tapered inner wall will expand when pipe or tubing is inserted to hold them snugly in place. They're often used for routing applications on metal, plastic, and fiberglass tanks.

Snap-In Pipe and Tubing Grommets

These grommets have two flanges that snap around holes and flex to compensate for misalignment and movement of pipe and tubing. They're often used for routing applications in panel walls.

Sanitary Sealing Grommets

Create a sanitary seal on through-wall piping, tubing, and cables in food-, cosmetic-, and pharmaceutical-processing areas.

Split Sealing Grommets

The two‐piece design makes it easy to install and seal these grommets around wire, cable, and cords that are already in place. Use them to keep out dust, debris, and moisture.

Create-Your-Own Split Sealing Grommets

Cut the center of these grommets with a utility knife to create custom IDs. The two‐piece design makes it easy to install and seal these grommets around wire, cable, and cords that are already in place. Use them to keep out dust, debris, and moisture.

Sealing Grommets

Create a tight seal around wire, cable, and cords with these grommets to keep out dust, debris, and moisture.

Apply heat and these grommets shrink around wire, cable, and cords to keep out dust, debris, and moisture.

Wet-Location Snap-In Sealing Grommets

Snap these grommets into place to hold wire, cable, and cords in wet locations and form a seal against dust, debris, and water.

Liquid-Tight Sealing Grommets

Rated IP68, these grommets form liquid-tight seals around wire, cable, and cords to protect them against dust as well as submersion in a maximum of one meter of water.

High-Temperature Grommets

These flexible grommets withstand temperatures of 450° F or greater, which is approximately twice as high as our standard grommets. Push them into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration.

Cam-and-Groove Hose Couplings
for Food and Beverage

Couplings are made of FDA listed materials, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. 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.

Twist-Claw Hose Couplings for Air and Water

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Threaded Hose Fittings for Hydraulic Fluid

Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 6,000 psi

Use these dust caps and plugs to keep contaminants out of your hose line.

Protective Plastic Plugs for
Cam-and-Groove Hose Sockets for Water

Insert these caps into a cam-and-groove socket to protect the end of the coupling from damage. The attached handle allows you to easily maneuver hose.

Dust Caps and Plugs for International Standard
ISO Minimal-Spill Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Use these dust caps and plugs to keep contaminants out of your hose line.

Plastic Cam-and-Groove Hose
Couplings for Chemicals and Petroleum

Couplings are plastic, which is lighter in weight than metal 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.

Plastic Cam-and-Groove Hose Couplings for Water

Made of polypropylene, these cam-and-groove couplings are lighter in weight than metal cam-and-groove hose couplings.

Dust Caps and Plugs for International Standard ISO A
Quick-Disconnect Hose Couplings for Hydraulic Fluid

Use these dust caps and plugs to keep contaminants out of your hose line.

Dust Caps and Plugs for Natural
and LP Gas Hose Fittings

To keep contaminants out of your gas line, add these dust caps and plugs to natural and LP gas couplings when they’re not connected. All work with couplings that are rated ANSI Z21.41/CSA 6.9 for use with gas fuel appliances.

Thread Sealants

Thread Sealants with PTFE

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Drip-Free Thread Sealants with PTFE

Apply this thread sealant stick without a mess.

Non-Hardening Thread Sealants with PTFE

Drip-Free Non-Hardening Thread Sealants with PTFE

Apply these thread sealant sticks without a mess.

Non-Hardening Thread Sealants

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.

Drip-Free Non-Hardening Thread Sealants

Apply this thread sealant stick without a mess.

Reusable Non-Hardening Thread
Sealants for Coarse Threads

Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads.

Reusable Non-Hardening Thread
Sealants for Fine Threads

Formulated to flow into small spaces, use these sealants between fine threads.

Thread Sealants

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Thread Sealants for Hydraulic
and Compressed Air Systems

Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media.

Non-Hardening High-Temperature Thread Sealants

Remaining pliable over time, these high-temperature sealants protect against leaks caused by vibration and pressure—they naturally fill voids before leaks can develop.

Thread Sealants for Refrigeration Systems

For use in refrigeration systems and applications exposed to strong chemicals, these sealants have excellent solvent resistance.

Thread Sealants for Oxygen Systems

Completely free of oil and chemically inert, these sealants are safe to use with wet and dry oxygen systems.

High-Temperature Thread Sealants

Thread Sealant Tape

High-Density Thread Sealant Tape

This tape has a higher density than standard tape for a better seal between threads.

Choose-a-Color High-Density Thread Sealant Tape

Use color to identify water, gas, and chemical connections.

Thread Sealant Tape

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.

Thread Sealant Cord

Wind this multifilament cord into the grooves of tapered pipe threads to quickly create a seal.

Thread Sealant Tape for Stainless Steel Threads

This tape contains nickel to prevent seizing and galling associated with stainless steel threaded connections. It’s also good for use with other metals.

Plumbing Fixtures and Drains

Drain Pipe Plugs

Seal unthreaded pipe ends with these plugs. They come with a band that clamps over the outside wall of your pipe and tightens with a screwdriver.

Cleanout Plugs

Close off your drain cleanout pipe with these plugs.

Floor Drain Backflow Preventers

Put an end to water damage from backed-up sewers. When water backs up, the rubber float will rise to seal off the drain. When water recedes, the float will drop for normal drainage.

Candle Wick Packing Seals

Super thin and flexible, these cotton yarn seals fit into tight spaces, such as in faucets.

Fasteners

Chrome-Plated Plugs for Stainless
Steel Socket Head Screws

Insert these plugs into the drive socket to block debris and provide a finished look.

Push-On Retaining Caps

Use these caps to hold components in place and protect shaft ends.

Thread-In Receptacles for Quick-Release Pins

Use a screwdriver to install these receptacles in a threaded hole.

Surface-Mount Receptacles for Quick-Release Pins

When you can't drill a through hole, use one of these flanged receptacles to provide a permanent, blind hole for a quick-release pin.

Retaining Caps for Quick-Release Pins

Use these retaining caps to secure the ends of quick-release pins in holes that are oversized or out of round.

End Caps for Mounting Rods

High-Temperature Slotted Rope Edge Seals

Made of fiberglass, these seals are woven tighter than High-Temperature Ultra-Conformable Slotted Edge Seals for increased durability. They resist grease, oil, hydraulic fluid, and solvents and can withstand temperatures up to 1000° F.

High-Temperature Ultra-Conformable
Slotted Rope Edge Seals

These loosely-knitted fiberglass seals are more flexible and conformable than High-Temperature Slotted Edge Seals. They resist grease, oil, hydraulic fluid, and solvents and can withstand temperatures up to 1000° F.
