Oil-Resistant Extreme-Pressure Stainless Steel O-Rings
Made of silver-plated 321 stainless steel, these O-rings can handle extreme pressure up to 11,000 psi. They resist grease, hydraulic oils, mineral oil, motor oil, and synthetic lubricants. These O-rings have a round profile and are suitable for a wide range of static and dynamic sealing applications. All are sized to the actual measured dimensions of SAE standard AS9373; they do not have a dash number.

Shaft Repair Sleeves
Also known as speedi sleeves, use these to repair and protect worn shafts for a smooth sealing surface without machining. Each sleeve comes with an installation tool. To install, place the installation tool around the sleeve and gently tap the installation tool until the sleeve covers the worn shaft surface.

High-Pressure-Rated Metal-Bonded Sealing Washers
Steel with PVC Plastic
Sealant Seal
Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.
Stainless steel washers are bonded to a PVC sealant that, when tightened, creates an impervious 360° seal around your fastener’s threads. They are not reusable. 304 stainless steel washers are more corrosion resistant than zinc-plated steel washers. They also have good chemical resistance. 316 stainless steel washers have excellent resistance to chemicals and salt water and may be mildly magnetic.

Ultra-Flexible Round Belting
Coiled-metal construction provides flexibility to bend around small-diameter pulleys and accommodate curved belt drives and misaligned pulleys. Cut belting to the length you need, thread connectors (sold separately) onto each end, and hook them together.
Stainless steel belting is corrosion resistant for use in harsh environments.
