Cobalt

Resists impact and rapid temperature changes—all with material certificates for traceability

Graphite

Compressible or conductive for making high-temperature seals, furnace parts, and crucibles

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering

Molybdenum

Retains its shape and strength in extreme temperatures—all with material certificates for traceability

Felt

Thicker and more absorbent than fabric for insulating, polishing, cushioning, and gasketing

Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Fastening and Joining

Dowel Pins

Align parts before assembly or use as a pivot, shaft, or hinge to join moving components

Dowel Pin Stock

Dowel Pin Stock

Cut to the length you need for positioning and holding parts in place

Stick Electrodes

Stick Electrodes

Flux coated for stability and speed when welding most metals

Fluid Handling

Mixer Shafts

Replace the shaft on mixers

Corrosion-Inhibiting Rods and Pads

Corrosion-Inhibiting Rods and Pads

Protect tanks, water heaters, and heat exchangers from rust; also known as sacrificial anodes

Sealing

Backer Rods

Insert into gaps before caulking to reduce how much sealant you need and improve adhesion

Facility and Grounds Maintenance

Rebar

Reinforces concrete to reduce the chance it will crack from expansion and contraction
