Description & Features

Manufactured by Hercules Sealing Products, these Buna-N seals are designed for applications requiring reliable dynamic or static sealing across a wide range of temperatures. The four-lobed profile of the Style QR Buna-N Quattro Rings, -113 Size, 5 Per Pack provides greater sealing surface contact than a standard O-ring, reducing spiral twist and improving seal stability in reciprocating and rotary applications.

Rated for use between -40°F and 240°F, the Buna-N compound offers good resistance to petroleum-based hydraulic fluids, making these rings well-suited for hydraulic cylinders, pneumatic actuators, and general industrial fluid power equipment. Pressure range varies according to diametral clearance. Each pack contains five rings.

Question by: Roger T on Apr 14, 2025, 1:31 PM
these quattro rings, do they hold up better than standard o-rings in a cylinder that's doing a lot of back-and-forth movement?
Answer by: Customer Support on Apr 16, 2025, 8:46 AM
Four-lobed seals like these handle reciprocating motion better than standard o-rings in most cases. The extra contact surface cuts down on the spiral twist you tend to get with round cross-section rings, and that means the seal stays seated more consistently through the stroke. For hydraulic cylinders running regular back-and-forth cycles, that added stability makes a real difference in how long the seal lasts before you start seeing seepage.
