Square O-Ring

The Moroso Square O-Ring (MPN 97321) is a precision rubber sealing component designed for applications requiring reliable fluid containment. This square o-ring is particularly useful in environments where maintaining a consistent seal is crucial, such as in automotive and industrial settings. It serves as an essential barrier against leakage in both pressurized and non-pressurized applications.

Engineered from premium elastomer material, the Moroso Square O-Ring is formulated to resist degradation from heat, oil exposure, and thermal cycling. Its square geometry allows for superior gland fill and reduced risk of extrusion compared to traditional round o-rings, making it ideal for applications that demand enhanced durability. This design ensures a reliable seal across wider contact surfaces and deeper grooves.

Ideal for mechanics and builders working on custom engines, fuel systems, or transmission components, this square o-ring is essential for preventing costly fluid loss during operation. Proper installation requires attention to gland sizing and groove depth, so consulting specific manuals is recommended. Whether for street, race, or marine applications, the Moroso Square O-Ring is a dependable choice.
