O-Ring and Seal for Food and Drug
The manufacturing and design of sealing
components for the food and pharmaceutical
industries has been the focus of GMORS since
1981. Our range of o-rings and seals match
every type of application and equipment used
in food processing and drug manufacturing.
GMORS provides advanced sealing
components to major equipment manufacturers
in the processing of food, life sciences and
biochemical industries. Meeting the
challenge set by the industries for greater
hygiene standards for elastomeric sealing
parts, GMORS offers o-rings and seals of
superior performance formulated to withstand
corrosive chemical media encountered during
sterilization processes. Complying to
standards set by USP Class VI, FDA 21 CFR
177.2600, 3A-Sanitary Standards and ADI
(Animal Derived Ingredients) Stands, our
elastomeric seals and parts resist the
deleterious effects of various cleaning
chemicals and active ingredients.
Seal Degradation and Food Contamination
Sterilization and cleaning of food
processing equipment are done at high
temperatures, and elastomeric seals are
constantly exposed to extreme service
conditions. Contamination of food during
processing happens when damaged elastomeric
sealing parts breaks off into fragments.
Microbial growth thrive under conditions of
surface deterioration of the o-rings and
seals, and advance the degradation of the
Performance Requirements for O-rings and
Seals used in Food Manufacturing
1. Resistance to various chemicals found in
2. Resistance to aggressive cleaning
chemicals encountered in clean-in-place
3. Surface of sealing components should not
hinder effective sterilization and cleaning.
4. Resistance to wear and abrasion.
5. Non-toxicity of seal material.
Areas of Application
Centrifugal pumps, centrifuges, fittings and
pipes, diaphragm and piston pumps,
separators, homogenizers, decanters.
Full certification of products in accordance
with international standards for
compatibility for use in food and drug
FDA 21 CFR 177.2600: This regulation
of the Food and Drug Administration (FDA)
stipulates the type and quantitative limits
of ingredients found in elastomeric
compounds that are used in the making of
molded products for repeated use for all
phases during food processing. This includes
the preparing of food, its packaging as well
3A-Sanitary Standards: The design of
food and beverage equipment and that of the
pharmaceutical industries based its criteria
for standards of hygiene on 3A-Sanitary
Standards. GMORS manufactures o-rings and
seals in accordance to the standards of
3A-Sanitary Standards, which also conform to
the guidelines of FDA CFR21.177.2600.
Diseases causing agents from ADI (Animal
Derived Ingredients) are excluded from
getting into the food processing chain
because our sealing products are ADI-free.
USP Class VI: The biocompatibility of
products and equipment used in the food and
drug, and health care industries must
conform with USP Class VI in their
manufacture. The strictest testing
procedures apply in USP Class VI, which is
the highest level within six classes under
the USP protocols.
An extensive range of elastomeric materials
is offered by GMORS that comply with the
above mentioned standards. The range of
materials offered include FKM, EPDM,
Silicone, FFKM, HNBR, NBR and more. Let us
know your service requirements and our
technical specialists will assist you with
the right choice of material, matching your
temperature and chemical conditions.
