Designed for dynamic and static sealing in hydraulic and industrial equipment, the Style QR Buna-N Quattro Rings, -112 Size, 5 Per Pack offer a four-lobed sealing profile that reduces friction and wear compared to standard O-rings. The quad-ring geometry provides two sealing surfaces on each face, improving seal stability and reducing the risk of spiraling in reciprocating applications.
Manufactured from Buna-N (nitrile) elastomer, these rings handle a temperature range of -40°F to 240°F and are well-suited for use with petroleum-based hydraulic fluids, mineral oils, and many common industrial fluids. Dash size -112 corresponds to a nominal 1/2 inch inner diameter with a 3/32 inch cross-section. Pressure capability varies with diametral clearance, making proper groove and housing design a key factor in application suitability. Each pack contains 5 rings. A Hercules Sealing Products offering, these rings are stocked for maintenance, MRO, and OEM replacement use.
