With a compressible flanged top, these plugs are designed to seal the ends of copper tubing often used in water supply lines, refrigerant lines, and HVAC compressors. All are sized to fit standard copper tube dimensions.

With a surface resistivity of less than 10⁵ ohms, these plugs not only dissipate electrical charges, but can be used as an electrical shield.

Flexible ridges or straps hold these plugs in place and allow them to fit a range of hole diameters.

Safeguard internally threaded BSPT connections from contaminants during fabrication and storage.

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

These plugs have excellent chemical resistance for masking parts during chemical finishing applications such as plating and anodizing. Use the smaller end of the plug to pull the larger end into a through hole to form a tight seal.

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

Keep hollow tapered plugs of various sizes on hand to solve whatever problems arise. The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters.

Often used as laboratory stoppers, these rubber plugs have good impact and abrasion resistance. They’re tapered to fit a range of hole diameters.

Sized to fit small openings, these tiny plugs fit snugly but can be removed easily using the flange. Their tapered design fits a range of hole diameters.

Pull the two built-in rings to quickly remove these plugs. All are tapered to fit a range of hole diameters.

The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters. Good for electroplating, paint baking, and powder-coating applications, they withstand temperatures up to 450° F.

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.

These plugs have excellent chemical resistance for masking parts during chemical finishing applications such as plating and anodizing. Their tapered design fits a range of hole diameters.

Flexible ridges or straps hold these plugs in place.

More durable than plastic plugs, these provide the most protection from abrasion and impact. Use them to eliminate sharp edges and create a finished look on metal fence and machine-guard posts. Drive them in place with a hammer for a secure fit.

Push these plugs into an opening and friction holds them in place.

Tapered prongs or a snap-in ring securely hold these plugs in place.

Keep metal snap-in plugs of various sizes on hand to solve whatever problems arise. Made of steel, these plugs are our most durable plugs for panels. Their tapered prongs snap into holes to securely hold them in place.

The wings on these plugs expand against the sides of a hole to form a liquid-tight seal. Pierce the plugs with round wire, cable, or tubing and they function as a grommet to create insulated holes.

Vents in the top allow air circulation and permit heat and fumes to escape. All of these plugs have wings that expand against the sides of the hole to lock them in place.

Slide these flexible vinyl caps on and they conform for a snug fit.

Made of rigid plastic, these caps are more wear resistant than vinyl caps but not as flexible.

The tethered design allows frequent access to the ends of pipe, tubing, and other round objects without ever misplacing the cap.

A long, textured pull tab provides a sure grip for quick removal even when wearing gloves.

Made of FDA listed materials, these caps are suitable for food contact.

Keep equipment safe from electrical currents with these caps that have a surface resistivity of less than 10¹² ohms.

Good for electroplating, paint baking, and powder-coating applications, these caps withstand temperatures up to 440° F or 570° F.

These flexible plastic caps are tapered to fit a variety of unthreaded and threaded objects.

Slide these flexible vinyl caps onto rectangular objects and they conform for a snug fit.

Made of rigid plastic, these caps are more wear resistant than vinyl caps but not as flexible.

Guard the corners of fragile materials such as glass and mirrors.

Protect externally threaded components from contaminants during fabrication and storage.

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.

Permanently seal pipe, tubing, conduit, and even crimped electrical connections. Slide these flexible caps on and use a heat gun to tightly shrink them to the shape of whatever they are covering. Their outer surface shrinks while the inner wall flows into voids to create a sealed connection.

Designed for propane tanks such as those on forklifts and grills, these caps protect tank valves during storage and transit. Push the caps onto the valves, then tear their tab to break the seal for easy removal.

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

Conceal and protect the tops of socket head or button head screws.

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

Stretch these caps over flared edges such as flanged tubing and valve handles.

Protect SAE hydraulic flanges during shipping, storing, and finishing applications.

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

A square O-ring prevents these piston seals from rocking in the groove.

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.

These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly. Also known as lip seals, U-cups have a sealing lip on both the inside and outside edges, so they can be used for rod and piston sealing.

Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston for better sealing performance at lower pressures than unsupported U-cup seals.

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

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.

A spiral seam gives this duct greater strength and rigidity than standard duct.

Turn the square head of the plug into the sealing ring to close off pipe openings.

Tighten the nut on these plugs to expand the seal.

Twist the easy-grip t-handle on these plugs to expand the seal.

These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line.

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve back pressure while testing.

Cover chimneys to reduce downdrafts and prevent obstructions from entering.

Keep rain and debris out of vertical exhaust pipe with these caps that open with slight pressure from exhaust.

Keep grease fittings free of dirt and moisture.

Inject or draw out samples while keeping vials sealed. These lids have a soft barrier that can be pierced with a needle. They are often used in chromatography.

Cover syringe tips when not in use to protect them and prevent leaks.
