Quad Rings Buna

Buna-N, also know as nitrile, o-ring is common and the most simplest types of seal with an excellent sealing property and durability. Recommended for use with crude oil, gasoline, propane, petroleum oils and water. It is used in engines, gearboxes and also can be found in anything from shower heads, garden hoses, pumps up to an aircraft. The “X” profile creates a stable seal that is more resistant to rolling in the groove than an O-Ring when used in a dynamic application. Multi-lobed design provides more sealing surfaces than standard O-Rings. Multi-lobed design provides more sealing surfaces than standard O-Rings. Grooves on the inside and outside diameter of these rings retain lubricant thereby lowering friction and extending packing life.
