V8.4X174.5 is a black Viton® (FKM) 70 Shore A O-Ring measuring an inside diameter of 174.5 mm (6.87 in), a cross section of 8.4 mm (0.331 in), and an outside diameter of 191.3 mm (7.53 in). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope. The catalog record notes: Metric O-RING, JIS P175.

It resists engine and transmission fluids, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) is known for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in ketones and esters or hot water and steam.

Common environments for this compound include oil and gas, automotive fuel systems, and aerospace.

V8.4X174.5 ships individually. Unit weight is approximately 58.845 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
