Designed for dynamic and static sealing in hydraulic and industrial equipment, this 7/32" x 1/16" quad ring seal from Hercules Sealing Products offers a four-lobed cross-section that provides improved stability and reduced rolling or twisting compared to standard O-rings. The quad ring profile maintains consistent contact with groove surfaces, making it well-suited for reciprocating and rotary shaft applications where seal integrity is critical.
The Hercules Quad Ring 7/32 X 1/16 is a compact seal intended for use in cylinders, valves, pumps, and similar hydraulic components where a reliable, low-friction sealing element is required in confined groove geometries.

Question by: Ricky J on Oct 25, 2025, 8:09 PM
these quad rings, do they actually stay put better than a regular o-ring in a reciprocating cylinder, or is that just marketing talk?
Answer by: Customer Support on Oct 27, 2025, 6:10 AM
Four-lobed seals like this one do hold their position better in reciprocating applications. A standard o-ring can roll or twist in the groove during back-and-forth motion, which leads to uneven wear and eventually a leak. The quad ring's profile keeps consistent contact on all four lobes, so it stays stable and doesn't walk around in the groove the way a round cross-section can. For cylinder work especially, that added stability makes a real difference over time.
