Due to our hobby (scuba-diving), we learned that O-rings for
SCUBA diving are either expensive or bad in quality in Thailand. Therefore we
decided to offer them in FKM (also called Viton which is the trademark of
DuPont Dow's) shore 90.
O-rings made of FKM are the preferred
choice for oxygen and nitrox compatibility in SCUBA diving applications.
FKM is an elastomer with excellent oil and oxygen resistance at high and
low temperatures, very good chemical resistance. Even for use with
ordinary air, most experts agree that FKM O-rings outperform common
Nitrile O-rings.
Our O-rings are imported from USA and have a guaranteed
shelf life of 20
years. They are conform to US military standard MIL-R-83248, Type 1,
Class 2; AMS7259 and AMS7279 and to the EC directive 1999/92/ED,94/9/EC, RoHS Directive 2002/95/EC. Certificates Of Conformance
are available on request.

after several month of testing:
"I still can't tell how long these O-rings
will work, due to the fact all still look like brand new."
