White FKM: identify the compound as well as the colour
AKVT’s listed product is a white FKM O-ring. FKM identifies the elastomer family; the exact compound determines properties such as hardness and service limits. Parker’s handbook lists multiple FKM compounds with different specifications. A general FKM rating should not be treated as the rating of this particular white formulation. Parker O-Ring Handbook.
For your quotation, ask AKVT to confirm the supplier’s compound designation, hardness, dimensions and application suitability. Colour alone does not identify the grade.
Product details for your enquiry

| Temperature and pressure | Provide continuous and peak conditions for review against the selected part |
| Food-contact requirements | Specify the required documentation and conditions of use |
How to specify O-ring dimensions
Use inside diameter (ID) and cross-section (CS) to describe the size. Measure a relaxed sample without stretching or compressing it, and include a drawing or original part number where possible. Parker O-Ring Handbook: dimensions and ordering.
| Measurement | Meaning | Example only |
|---|
| ID | Diameter of the opening inside the ring | 20 mm |
| CS | Thickness of the circular rubber section | 3 mm |
| OD | Outside diameter: ID + 2 × CS | 26 mm |
Example enquiry: “White FKM O-ring, 20 mm ID × 3 mm CS, 100 pieces; compound and hardness to be confirmed.” These numbers illustrate the ordering format, not a stocked AKVT size or a recommended fit.
A worn or distorted sample may not show its original dimensions. Include the equipment drawing, groove dimensions or original specification when available.
Application examples to discuss with AKVT
General FKM material guidance includes oil and fuel service, subject to the selected compound and actual medium. Parker: fluorocarbon O-ring material guidance.
For a pump cover replacement, send the original seal specification and fluid details. For an equipment maintenance enquiry, include the operating and cleaning temperatures. For a process connection, identify the chemical, concentration and exposure conditions. These examples are starting points for review; suitability must be established for the quoted white compound.
Selection FAQs
Is every white FKM O-ring food grade?
No. Request documentation for the specific compound and intended conditions of use. Parker’s food-industry materials brochure distinguishes individual compounds and their compliance information; a colour or polymer-family label does not replace that documentation. Parker: Materials for the Chemical Process and Food Industries.
What is the operating temperature of this white FKM grade?
Ask AKVT to confirm the range against the supplier’s compound datasheet. Include continuous temperature, short excursions and the fluid involved. A numerical rating is not provided here without that product-specific evidence.
Will FKM work with every chemical?
No. Select against the actual fluid and operating conditions. Parker’s material selector includes fluid compatibility, temperature and hardness inputs. Share cleaning agents as well as the process fluid. Parker O-Ring Selector.
What if I only know the old part number?
Send it with the equipment model and quantity. Add photographs or a drawing by email if available, and state whether the replacement must meet a particular material specification.
Request a white FKM O-ring quotation
Include ID × CS and units, quantity, material or compound reference if known, medium, pressure, temperature, required documentation, delivery location and required date.
