Match the hole and the sealing land independently
A rubber washer creates a flexible contact layer around a fixing or opening. These black rings have flat faces and no adhesive. The 212 stock dimensions cover small fastener interfaces through larger equipment contact points, with each ID, OD and thickness retained as a complete size.
The inner diameter clears the fastener or passage; the outer diameter establishes the contact footprint. Select both before choosing thickness. Include the rubber compound and operating medium in the order so the chosen dimensions remain tied to the intended service.

All dimensions are nominal. Choose the full SKU to keep colour and dimensions together. Price, packing and freight are quoted for the selected quantity.
WHERE IT FITS
Around fasteners and static openings
Static clamped connections
Fit the washer between seats designed to compress a flat ring. Match material requirements to the fluid and temperature.
Equipment spacers
Use the selected nominal thickness at a local mounting point and account for compression under the assembled load.
BEFORE YOU FIT THE PART
Selection & installation
Start with the contact geometry, then check the part in the assembled condition.
Adhesive-backed assembly options →Read all three dimensions
Two washers with the same ID can have different contact areas. Keep ID, OD and thickness together on the order.
Describe the environment
State oil, water, outdoor exposure or other media so the rubber requirement is explicit. Black colour alone does not identify a compound.
Control the clamp condition
Use the assembly design to define tightening and compression. The dimensional SKU does not specify a torque or pressure rating.
Fit the selected construction
Place the ring flat on its seat, align the centre opening, and apply the clamping condition specified for the joint.

Ordering & product questions
Are these silicone washers?
This is the black rubber series. Milky-white silicone washers have separate material-specific SKUs and their own stock page.
Do these washers have adhesive?
No. The listed A0 stock parts are retained by the assembled joint or fixing.
Can a flat washer replace an O-ring in a groove?
Use the seal geometry specified for the joint. A flat washer and a circular-section O-ring have different section dimensions and seating requirements.
