Hydraulic & Fluid Power Systems
Seal selection should follow the hydraulic fluid, temperature, pressure, and gland design.

TECHNICAL OVERVIEW
FKM O-Ring Hardness & Supply Options
FKM O-ring hardness commonly runs from 60A to 90A. The final choice follows the medium, temperature, pressure, and seal movement; the FKM70 data below is one documented reference.
RFQ INPUTS
What we need to review your FKM requirement.
The FKM70 values on the right are a reference point. With these four inputs, we can check the hardness, compound, and sealing duty against your application.
- 01Sealing mediumName the gas, liquid, concentration, or process fluid.
- 02TemperatureInclude the normal and peak operating range.
- 03Pressure & motionState pressure and whether the seal is static or dynamic.
- 04Size & quantitySend the ID × cross-section, standard, drawing, and expected volume.
Reference values from the FKM70 material data sheet. They are not a batch certificate of analysis and do not replace application-specific validation.

APPLICATION REVIEW
FKM O-Rings for Industrial Sealing Applications
The right FKM compound depends on the sealing medium, temperature, pressure, and operating conditions—not just the size on the drawing.
Pumps & Valves
For appropriate static and dynamic sealing duties after operating-condition review.
Chemical Processing Equipment
Compound suitability needs review against the chemical medium and concentration.
Industrial Equipment OEMs
Standard and drawing-based O-rings for production assemblies and replacement programs.
SUPPLY ASSURANCE
Quality You Can Verify
Clear specifications, agreed inspection requirements, and supporting documentation reduce uncertainty in industrial component procurement.
Dimensional verification
Inspection can be agreed against the O-ring dimensions, tolerances, and applicable standard named in the RFQ.
Material documentation
Compound specifications and applicable test reports can be reviewed against the quotation request.
Lot identification & packaging
Discuss labeling, packaging, and traceability requirements for repeat procurement before order release.
Sample approval before bulk production
Samples and inspection criteria can be agreed before a production order proceeds.
Inspection photographs, material reports, and packaging examples should be confirmed for the requested supply program; this page does not represent a certification claim.
OEM & BULK SUPPLY
From First RFQ to Repeat Supply
The form below starts the quotation request. These are the procurement decisions that can be aligned once product requirements are under review.
01One consolidated review
A BOM, size list, or drawing package keeps related O-rings inside one technical review instead of splitting them across separate requests.
02Specification alignment
Before a first production release, align dimensions, hardness, documentation, and inspection requirements against the approved request.
03Repeat-supply setup
For approved parts, define packaging, lot identification, and scheduled purchasing requirements for the next order cycle.
