Frequently Asked Questions.
Why should we prefer your O-rings? The average diver might be aware of two main categories of O-rings commonly used in SCUBA
equipment NBR and Viton, and maybe two different O-ring hardness Sh70 (Soft) and Sh90 (Hard).
The reality is that there is a great variety of materials used in the scuba dive O-ring industry with the
used of compounds like Nitrile or else called Buna N, EPDM, Polyurethane and Viton®. However, there are many subtypes even within each compound category and same hardness, each having its
own properties and each having its recommended field of use.
Nowadays a great variety of O-rings are used, in scuba equipment than the traditional NBR-Buna-N
material, like EPDM Sh70, EPDMSh85, Viton® Sh75 -Sh90, Polyurethane Sh70-Sh90 and so on.
By selecting SCUBAGASKETS you eliminate luck and you ensure the use of correct seals for the
specific application. At the moment ScubaGaskets has more than 200 high quality specialised Scuba
O-rings
Your O-rings cost more than other brands’ do. Two issues to consider when you are buying O-rings from ScubaGaskets:
• There are no hidden costs with SCUBAGASKETS. We simply let you know the price to
your door, not the one that the product leaves our warehouse with. Everyone can
understand how the initial (ex-works) price increases until the product reaches its final
destination; your address! Calculate above all shipping fees in addition to that calculate
handling or whatever costs the supplier will have to charge on top of the advertised price
and you will end up with a completely different price.
With our free shipping registered mail policy, for all orders for just over 50 euros, we let you
know the cost per product before you even click the checkout button.
• Even after the calculations there might be cheaper solutions! Fair enough! Yes. we don’t
claim being the lower cost supplier. Instead our focus is on high-tech OEM applications and
we are striving to offer our customers the best possible quality for their application and the
best value for money. Our O-rings are not general-purpose O-rings. They are carefully and
specifically selected and manufactured for SCUBA applications.
What is FKM?
FKM is the ASTM designation for the fluoroelastomer category. It is not a mark of quality. Not all FKMs
are equivalent, and some may fall short on desired performance.
What is Viton? Viton is a trademark of DuPont Performance Elastomers. Viton® was introduced in 1958 and
scientists and engineers have relied on DuPont and now DuPont Performance Elastomers Viton®
for its superior performance and unique properties ever since. However, DuPont Performance
Elastomers is not the only company that manufactures FKM products. Many people in the industry
incorrectly refer to any and all FKM elastomers as Viton®. Bear in mind that not all FKMs are
equivalent. As a result, you could end up with sealing products that are not the type of Viton® you
need let alone made of 100% virgin DuPont Performance Elastomers Viton®. Products not made
from DuPont Performance Elastomers Viton® may fall short of the expected performance levels
afforded by the stringent quality standards.
DuPont Performance Elastomers has set for Viton® which is manufactured at ISO 9002 registered facilities worldwide.
Are all fluoroelastomers "Viton®" fluoroelastomers? In a word. no! Only DuPont Performance Elastomers manufactures Viton® fluoroelastomer. Because Viton® is an established industry standard many people incorrectly refer to any and all fluoroelastomers as Viton®. To ensure you're getting the highest quality fluoroelastomer available insist on products made only with DuPont Performance Elastomers virgin Viton®.
How do I know I am getting O-rings made with Genuine Viton® fluoroelastomer? Look and Ask! Be sure to make Viton® an element of your part specification. When parts are shipped. look for the Genuine Viton® trademark. Not every supplier has a right to use the word Viton® in its products!
Why does VITON®
matter?
It is your guarantee of product integrity. When you use
products that carry this trademark, compliance to OSHA
Mechanical Integrity Section 1910.119 is assured. It means
that the parts offer the superior performance that only DuPont
Performance Elastomers Viton® fluoroelastomer provides.
Other fluoroelastomer parts may include blends and other
rubbers that deliver inferior heat and fluid resistance
performance.
Who can use the word "VITON ®?" Only manufacturers who have signed a formal agreement with DuPont Performance Elastomers can use
this trademark on their products. The manufacturers are selected carefully for their knowledge their quality
standards and for their ability to help you select the correct type of Viton® for your application. A well-
written specification will communicate your needs to your supplier who has up-to-date information about
the variety of Viton® performance types and who can suggest the most cost-effective recommendation.
Dose O-Ring colour matters? In a word No. At the very first steps of Scubagaskets, the decision to develop the black Viton® O-rings
product range for Nitrox applications due to the superior properties over brown or green material was taken.
The quality tests indicated that Black Viton compared to Green or Brown Viton with all parameters constant
except for the colour is favourable. It has higher strength better stability and better elastic properties
originally (brand new) and also after exposure to extreme situations that cause material fatigue. It also
possesses higher resistance to surface damage. At that time whatever O-ring had a green colour was
assumed to be Viton! The production of any colour material is feasible but requires the addition of pigments
and other chemicals which by definition change the elastomer’s physical characteristics. As divers we are
all highly sensitive to quality issues we would be very reluctant to compromise any amount of quality for the
sake of being able to identify Viton® by colour or follow the market trend. Furthermore, we should be aware
that nitrile-type and other materials may indeed be produced in green or brown or any other colour we can
imagine. If we judge only by colour then there is a great risk of falling into errors. We have chosen to
sacrifice the easy identification by colour for getting the benefit of the best possible quality. That was back
in 2006. As science evolves in such high rates in many areas, the discovery of new colour pigments
allowed the coloration of our new Viton® O-ring category in green colour with neglectable alteration of the
physical properties of the O-ring. Those pigments were used by scubagaskets for the creation of the
“Green” Viton® scuba O-ring range that is specifically developed and manufactured for PURE Oxygen
environments. The use of this new pigments, in this case, solved a very significant problem, that is the
differentiation of the first Viton product range intended for Nitrox from the O-rings rated for Pure oxygen
use. Without making any discounts on the O-ring quality scuba gaskets, became the first brand globally in
2018, to have available for sale 2 different kinds of Viton® Scuba O-rings, one for Nitrox Black Viton® and
Green Viton® for pure oxygen use!
What else do we mean by quality?
35 Years of O-ring Technical Expertise in the industry: including general industry, heavy chemical industry (offshore), Automotive, water and Heating, semiconductor industry, and medical industry. Also, we are very much involved in the Aerospace industry, working closely with all leading European companies. This assures you that you have the best selection for SCUBA gear with regards to technical characteristics. The O-rings are packed in straight-sided jars, which have been specifically designed so you can place them on top of each other and save storage space. The containers are closed with safety seal, which allows you to ensure quality before you buy by checking that the seal is in place
Very recently, due to our environmental sensitivities, we offer an
alternative packing that is made out of carton in order to reduce the
use of plastics as much as possible. Is up to the consumer to
choose the most suitable packing for him. The carton packing also
protect the O-rings from elements but it cannot be used for staking
due to its shape. Usually our customers use in their first order the
plastic packing, and at their following orders use the carton packing
in order to refill their plastic containers.
