Chemical-Resistant Low-Temperature Fluorosilicone
O-Rings for Tube Fittings with Straight-Thread Connection
Flexible even at temperatures as low as -75° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol. Also known as Boss O-rings, these O-rings work with tube fittings with a straight-thread connection, such as BSPP, UN/UNF, and most metric fittings.
These O-rings meet MIL and ASTM standards for the chemical and physical properties of fluorosilicone. They also meet SAE AS568A for standard O-ring sizing.
