Copper Crush Washers
Annealed copper sealing washers for high-temperature joints.
A leak here usually means downtime, contaminated oil and a failed bearing. Tell us the shaft / bore size, speed, medium and temperature — we will match the profile and compound rather than quote from a generic table.

Model numbers for this family
For this family we quote to drawing or sample. Send the part number, dimensions (ID × OD × width) and quantity on WhatsApp and we will confirm the specification.
The image folder had no model labels, so a photo is still a style, not a part number. Verified sizes now come from your spreadsheets via the Size Finder; MOQ and prices are never published. Tell us which photo maps to which size and we will link them into full spec cards.
Three things we need to quote
- Dimensions — d × D × W, or a drawing / sample
- Duty — medium, temperature, pressure or shaft speed
- Quantity — target order quantity and delivery destination

Applications
Where this family is used
Automotive & Transmissions
Wheel hubs, crankshafts, gearboxes and differentials — where heat, oil and shaft runout destroy a cheap seal long before the service interval.
Hydraulics & Pneumatics
Cylinders, valves and fittings that leak under pressure pulses. Correct lip geometry and compound matter more than catalogue price.
Pumps, Gearboxes & Motors
Unplanned downtime costs far more than the seal. We size by shaft diameter, speed and medium, not by a generic part number.
Agriculture & Construction
Mud, dust and shock loads demand double-lip or cassette solutions with the right hardness and abrasion resistance.
