Sealing

Shaft Seals

Prevent leaks in motors, pumps, and gearboxes

U-Cup Seals

With a lip on both the inside and outside edges, they can be used for sealing rods and pistons

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

Piston Seals

Prevent leaks inside pistons by creating a seal against the cylinder bore

Spring-Loaded Seals

Spring-Loaded Seals

Seal rods and pistons with a wider range of temperature and chemical resistance than U-cup seals

Buffering Seals

Buffering Seals

Protect hydraulic cylinders from pressure spikes and shock in high-pressure applications

Packing Seals

Fill in gaps around pump shafts, valve stems, and agitators to prevent leaks

Packing Seal Lubricating Rings

Packing Seal Lubricating Rings

Install between layers of packing seals to distribute lubricants evenly; also known as lantern rings

Wear Rings

Guide rods and pistons to prevent uneven wear and extend the life of seals

Head Seals

Maintain a seal even under fluctuating pressure; more reliable than an O-ring with a backup ring

Cushioning Seals

Cushioning Seals

Reduce wear and noise in air-powered cylinders by blocking the piston from hitting the cylinder body

Wear Ring Stock

Wear Ring Stock

Cut to make wear rings that fit any rod or bore to prevent uneven wear and extend the life of seals

Edge Seals

Block dust, water, and wind from entering the gaps around doors and windows

Rope Seals

Insulate the edges of oven, furnace, and boiler doors to keep heat in

Thread Sealants

Thread Sealants

Create a seal between threaded connections to prevent loosening from vibration

Sealants

Fill and seal gaps in metal, plastic, wood, and other materials

O-Ring Bonding Kits

O-Ring Bonding Kits

Everything needed to make O-rings

Pipe Gaskets

Form tight seals when connecting flanged pipe fittings

Containers, Storage, and Furniture

Tank Patches

Spin with a handheld electric router to seal holes in plastic tanks and containers

Safety Equipment

Drum Patches

Patch drum leaks to prevent their contents from spilling
