Custom rubber washers are annular components defined by their inner diameter, outer diameter and thickness. Hongjie manufactures washers to drawings or samples, with compound selection based on contact media, operating temperature, compression load and environmental exposure.
Custom rubber washers are annular components with a defined inner diameter, outer diameter and thickness. Geometry, hardness and material should be specified together with the working medium, temperature and compression conditions.
Define ID and OD from the bolt, shaft, opening and available contact area.
Specify washer thickness and any critical dimensional tolerances that affect fit or sealing.
Select hardness according to required deformation, clamping force and compression behavior.
Identify contact with oil, water, fuel, air or chemicals before compound selection.
Provide normal and maximum temperatures so the rubber compound can be reviewed for the service range.
Drawings or samples help confirm geometry, tolerances and installation requirements before quotation.
Define geometry and service conditions before selecting the rubber compound. The table below summarizes the main inputs used for engineering review.

A useful RFQ starts with washer geometry and service conditions. Provide the drawing or ID, OD and thickness together with the medium, temperature and compression requirement.
Primary Geometry
Service Conditions
Provide the following information so geometry, material and inspection requirements can be reviewed against the actual assembly.
Review the washer geometry, service conditions and inspection requirements together before production.
Confirm ID, OD, thickness and critical tolerances from the drawing, dimensions or sample.
Match the compound to the working medium, normal and maximum temperature, and environmental exposure.
For flat sheet-cut silicone parts, see flat die-cut silicone washers. For three-dimensional molded silicone profiles, see molded silicone washers with 3D profiles. For solid round parts without a center hole, see solid rubber discs without a center hole.
Define critical dimensions, visual criteria and required documentation before production.
