Custom Industrial Rubber Seals in NBR, FKM, EPDM and Silicone

Custom Industrial Rubber Seals in NBR, FKM, EPDM and Silicone

Custom industrial rubber seals made to the required geometry and service conditions. NBR, FKM, EPDM and silicone options are reviewed with the drawing, hardness requirement and inspection scope. ISO 9001 quality management supports the manufacturing process.

Product introduction

Custom industrial rubber seals are selected by geometry, compound and service conditions. NBR, FKM, EPDM and silicone options can be reviewed from the drawing, hardness requirement and inspection scope.

Specify the applicable drawing, material requirement and test standard for your application. Chemical, temperature, food-contact and other approvals depend on the selected compound and agreed test or documentation requirements.

Material Expertise: Choosing the Right Elastomer

Compare each candidate against the actual medium, temperature, movement, pressure cycle and any approval or test requirement. A polymer family alone does not confirm suitability:

1. NBR (Nitrile Butadiene Rubber)
NBR may be considered for selected oils, fuels and hydraulic fluids. Confirm additives, temperature and compound grade before use.
Service Temperature: Confirm limits for the selected compound and medium.
Typical use: oilfield and hydraulic seals where compatibility is verified for the operating fluid.

2. FKM (Fluoroelastomer)
FKM may be considered for selected oils, fuels and chemical media. Confirm the compound against the actual fluid, temperature and exposure.
Service Temperature: Confirm limits for the selected compound and medium.
Typical use: selected fuel, chemical and higher-temperature sealing applications after fit and compatibility review.

3. EPDM (Ethylene Propylene Diene Monomer)
EPDM may be considered for water, weather or ozone exposure. Check compatibility where oils or hydrocarbons are present; confirm the steam and temperature grade.
Service Temperature: Confirm limits for the selected compound and medium.
Typical use: water or outdoor sealing where the medium and temperature match the selected compound.

4. Silicone (VMQ)
Key Properties: Flexible silicone compound options. Medical or food-contact use requires documentation and testing for the specific grade.
Service Temperature: Confirm limits for the selected compound and medium.
Typical use: flexible seals and gaskets by drawing; regulated uses require grade-specific documentation and testing.

For industrial maintenance and OEM procurement, define the seal interface first: groove or mating dimensions, compression space, movement, pressure cycles and actual service medium. Include continuous and peak temperatures, cleaning fluids and the required inspection documents. For replacement parts, identify the equipment and failure symptoms rather than choosing solely by the old seal color.

Our Customization Capabilities

Specify the requirements that affect seal function and acceptance: compound, dimensions, hardness, color, marking and packaging. Feasibility is confirmed against the drawing or an approved sample.

Why Partner With Us?

• Quality management: The company is certified to ISO 9001. Agree batch inspection and any tensile, compression-set or aging test method in the purchase specification.

• Process and tolerance: Manufacturing method and critical tolerances are reviewed against part geometry and the agreed acceptance requirements.

• Order information: Lead time, shipping method and documentation are confirmed for the destination and order requirements.

• Drawing review: Provide mating dimensions, service medium and inspection criteria for review before quotation.

FAQ

Q1: What is the minimum order quantity (MOQ) for custom components?
A: MOQ depends on compound, geometry, tooling and inspection requirements. Confirm the applicable minimum for the quoted part.

Q2: How do I know which material is best for my application?
A: Provide the medium and additives, continuous and peak temperatures, pressure cycle, movement and approval requirements. Candidate compounds can be reviewed, then confirmed for the actual application.

Q3: Do you offer rapid prototyping?
A: Confirm the prototype route after the geometry and compound are reviewed. A dimensional model can support a fit check; production-molded samples are needed for the agreed functional tests.

Q4: What is your standard lead time?
A: Lead time is confirmed in the quotation after reviewing compound, dimensions, tooling status, quantity and inspection requirements.
