Food Media
Identify the food or beverage, including fats, oils, acids, alcohol and mixtures where relevant. Specify contact duration and whether the seal contacts the product directly or indirectly.

FDA Food-Grade O-Rings — Supply & Application Review
Discuss O-rings for food-processing and beverage equipment with FLUID. Start with the food medium, operating conditions, cleaning cycle and seal design. The specific compound, applicable food-contact requirements, supporting documents and supply feasibility are then reviewed for your project.

01 / FOOD-CONTACT APPLICATION REVIEW
Start with the Food-Contact Application
Food-contact O-ring selection starts with the process and sealing arrangement, not a short list of polymers. In food-processing and beverage equipment, review these four factors together before choosing a compound or requesting supporting documents.
Operating Conditions
Share normal and peak temperatures, pressure and pressure cycles, and whether the seal is static or dynamic. Movement, friction and wear can change the selection.
Cleaning & Sanitation
Include cleaning agents, concentration, exposure time, rinsing and any CIP/SIP cycles. Cleaning conditions may be more demanding than normal production.
Seal Design
Review the gland, squeeze, tolerances, surface finish and assembly access. The seal must fit the equipment design, cleaning needs and installation conditions.
02 / FOOD-CONTACT APPLICATION REVIEW
Understanding FDA 21 CFR 177.2600
21 CFR 177.2600 addresses rubber articles intended for repeated use in contact with food. Its provisions cover permitted formulation ingredients and applicable extractives requirements for the finished article, subject to the stated limitations. A material-family name or an extraction result alone does not establish every requirement.
Compound formulation
The base polymer, additives and their limitations matter. Colour and a generic designation such as silicone or FKM do not establish food-contact compliance.
Extractives testing
A test report applies to the identified sample and listed conditions. Aqueous-food and fatty-food extraction requirements are different; evidence for water extraction must not be extended to fatty-food contact.
Intended use
Match the compound, finished product form and supporting evidence to the food type, contact duration, temperature and repeated-use conditions. Laboratory extraction testing does not demonstrate seal life or cleaning resistance.
03 / FOOD-CONTACT APPLICATION REVIEW
Food-Processing and Beverage Equipment
Potential applications include appropriately designed seals in valves, pumps, pipe connections and other processing equipment. Review the actual product medium, contact time, normal and peak temperatures, working pressure, pressure cycling and seal geometry.
Static sealing
Check gland dimensions, squeeze, tolerances and access for assembly and cleaning. A food-contact material report does not verify the hygienic design of an equipment assembly.
Dynamic sealing
Movement introduces friction, wear and possible particle generation. Review speed, stroke, lubrication and contact surfaces separately; a static-seal selection cannot automatically be used in dynamic service.
04 / FOOD-CONTACT APPLICATION REVIEW
Cleaning, CIP/SIP and Installation
Share the cleaning chemicals and concentration, temperature, exposure time, frequency and rinsing procedure. Clean-in-place (CIP) and sterilise-in-place (SIP) cycles can impose conditions different from normal production; do not assume a food-contact extraction report validates those cycles.
Chemical and thermal exposure
Evaluate process media and cleaners together, including alternating exposure, steam where used, cooling and repeated cycles. Swelling, hardening or loss of sealing force can affect performance.
Gland, assembly and cleanliness
Check surface finish, crevices, gland access and seal retention. Protect the O-ring from sharp edges, twisting and excessive stretch; agree on suitable assembly aids, handling, packaging and cleanliness requirements.
05 / FOOD-CONTACT APPLICATION REVIEW
Material Selection and Documentation Support
VMQ / Silicone, NBR, FKM and EPDM are examples of material families that can be evaluated, not an exhaustive list of food-contact sealing options. No family name alone establishes compliance, application suitability or availability of a particular compound.
For VMQ / Silicone, review flexibility, tear and abrasion sensitivity and exposure to fats or cleaners. For NBR, assess oils and fats together with hot cleaning and steam exposure. For FKM, assess the process fluid and cleaning chemistry, especially hot water, steam or alkaline cleaners. For EPDM, assess water-based service and cleaning while checking limitations with oils and fats.
Other materials require confirmation of the specific grade, regulatory basis and supply feasibility before any compliance or supply commitment. Non-rubber polymers may fall under different FDA provisions; 21 CFR 177.2600 must not be applied automatically to every polymer seal.
Third-party extractives reports are available for selected VMQ, NBR and FKM samples tested with reference to 21 CFR 177.2600. These are sample-specific records, not a claim that every formulation or food-contact application meets the requirements. Applicable documentation and supply feasibility are reviewed project by project.
EPDM documentation must be assessed for the proposed compound and contact conditions; it is not presented here as broadly verified for food contact. Water-extraction evidence alone does not establish suitability for fatty-food contact.
06 / FOOD-CONTACT APPLICATION REVIEW
FDA, REACH and RoHS Documentation
These requirements address different questions and are not interchangeable. Documentation support is reviewed on a project-specific basis; existing files do not establish coverage for every compound, finished O-ring or market.
FDA food-contact requirements
Review the applicable food-contact provision, formulation, sample identity, extraction scope and intended use. Do not substitute a generic material statement for evidence linked to the proposed product.
REACH
REACH concerns chemical substances and applicable restrictions or communication duties. Determine the relevant obligation and the specific product and document scope; it is not a food-contact approval.
RoHS
RoHS restricts certain substances in electrical and electronic equipment within its scope. A RoHS document does not establish food-contact suitability. Confirm whether it is relevant to your project and which product it covers.

09 / TECHNICAL REVIEW FAQ
Food-Contact O-Ring FAQ
Does a silicone, NBR, FKM or EPDM O-ring automatically meet FDA food-contact requirements?
No. Suitability depends on the specific formulation, finished article, applicable evidence and intended conditions of use. A polymer name, colour or generic material specification is not sufficient.
What does an extractives test report demonstrate?
It records results for the identified sample under the listed extraction conditions. Check the test scope and its relationship to the proposed compound and finished product. Water-only testing does not establish suitability for fatty-food contact or every repeated-use application.
Can a food-contact O-ring be used in CIP or SIP service?
Not on the basis of food-contact documentation alone. Cleaning chemistry, concentration, temperature, steam exposure where applicable, duration and repeated cycles must be assessed together with sealing performance.
Can REACH or RoHS documentation replace food-contact evidence?
No. They address different regulatory purposes. Tell us which documents your project requires so their relevance and coverage can be reviewed for the proposed product.
Can FLUID review a custom food-contact O-ring requirement?
Yes. Share the drawing or dimensions, preferred material, media, operating and cleaning conditions, required documents and quantity. The specific compound, available evidence and supply feasibility are confirmed per project; not every requested combination is assumed available.
