About Cylinder Seals

Rod wipers scrape dirt, dust, and moisture from the rod, preventing contamination inside your cylinder.

Rod seals maintain the pressure inside cylinders and prevent fluid from leaking out.

Wear rings guide the rod and piston to prevent uneven wear and optimize seal performance.

Head seals are a more reliable alternative to the standard O-ring/backup ring combination—they resist twisting and remain stable even in applications with fluctuating pressure.

Buffering seals protect hydraulic cylinders from pressure spikes and shock in high-pressure hydraulic applications.

Cushioning seals minimize wear and noise in air-powered cylinders by preventing the piston from slamming against the cylinder body.

Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks.

Rod Seal Installation Tools

Install flexible seals, wipers, and O-rings. These tools are not for use with rigid materials, such as PTFE and nylon.

Changeable-Tip Corkscrew Puller Sets

Sets include an assortment of handles and tips for pulling material out of tight spots. Replace tips when they become worn or to use a different style. Also known as packing extractors and packing pullers, they are often used to extract packing material from pump and valve seals.

Corkscrew tips twist into material for a firm hold.

Wood screw tips are used to drill into and remove hardened packing when corkscrew tips are unable to get a secure hold on your material.

Machine screw tips thread into tapped holes. They're good for removing stuck or seized metallic components that can't be gripped easily.

Brush tips have stiff bristles that clean debris out of cavities after material has been pulled out with a screw tip.

Nonsparking Corkscrew Pullers

Made of beryllium copper with an aluminum-bronze handle, these pullers satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. They also are nonmagnetic. The corkscrew tip twists into material to provide a firm hold while the handle provides the necessary leverage for pulling. Also known as packing extractors and packing pullers, they are often used to extract packing material from pump and valve seals.

Warning: Do not use these tools in direct contact with acetylene.
