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.

Customer comments:
1) From Werner, PADI-instructor at the Dive Center in Chumphon Thailand (Webpage: http://www.divechumphon.com/, Email: Contact@DiveChumphon.com 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."
