NBR, HNBR or Silicone Rubber O-Rings for Factory Quotation

Factory O-Ring Quotation: Compare the Same Compound, Size and Inspection Scope

Identify tooling and sample requirements for custom dimensions so the quotation scope is clear. Confirm the current price and delivery terms for the approved specification. AS568 is a dimensional reference, and an O-ring pressure rating requires the complete gland and compound data.

For a factory quotation on NBR, HNBR or silicone O-rings, provide the exact size and compound specification together with quantity. Define the required inspection, colour and packing so quotations refer to the same part. Standard-size and custom rings require drawing or size confirmation; unit price depends on the agreed specification and order scope.

Application of the rubber o ring:

For hydraulic or oilfield equipment, identify the actual fluid, temperature, pressure cycle and static or moving gland. Specify the grade needed for that duty before comparing prices. NBR, HNBR and silicone must not be substituted solely to reduce cost; special gas-service or contact requirements need separate qualification.
