Discuss application

Materials

Compound options for real working conditions

Tell us the media, temperature, pressure and assembly environment. We can help review suitable material options.

NBR

Cost-effective option for many oil-resistant industrial sealing applications.

NBR O-ring RFQ

HNBR

Reviewed when heat, oil, wear and mechanical performance need to exceed standard NBR.

FKM

Reviewed for higher temperature, fuel, oil, chemical and demanding equipment projects.

FKM O-ring RFQ

EPDM

Often discussed for water, steam, weathering and HVAC sealing conditions.

EPDM O-ring RFQ

VMQ / Silicone

Useful when flexibility, color, food-contact review or wide temperature range matters.

Silicone O-ring RFQ

CR / Chloroprene

Discussed for weathering, ozone, moderate oil exposure and general industrial profiles.

View Complete Material Guide Includes core elastomers, specialty options and PTFE as a non-elastomer sealing material.

Process

From drawing to production quote

FAQ

Common RFQ questions

What files can I upload?

PDF, DWG, DXF, STEP, STP, JPG and PNG files are supported. Please keep the file under 20MB.

Can you quote from a sample photo?

Yes. A clear photo can start the discussion, but final pricing may require confirmed dimensions or a drawing.

Can you help choose the material?

Yes. Share temperature, media, pressure and application details so the engineer can review suitable options.

What is your MOQ and lead time?

MOQ and lead time depend on size, material, tooling, quantity and inspection documents. Send the RFQ details and we will confirm them with the quote.

Can you provide certificates or inspection reports?

Tell us the required standard before quoting. Available documents depend on the compound, supplier data and project requirements.
