Side Bell O-Ring (Thin)

The WINTERS Side Bell O-Ring (Thin), model 7403T, is a precision rubber replacement ring designed for 4 and 6-rib side bell compressors and similar hydraulic equipment. This thin-profile o-ring delivers reliable sealing performance in demanding industrial and field applications where pressure containment and fluid retention are critical to operational integrity.

Constructed from durable elastomer material, this o-ring is engineered to withstand the cyclic compression and thermal cycling inherent in side bell pump and motor designs. The thin profile reduces volumetric displacement while maintaining full sealing capability—a key consideration when space constraints limit component envelope. At 0.02 lbs with compact dimensions, it fits standard side bell assemblies without requiring modifications to existing equipment or housings. The cross-sectional design ensures even load distribution across the sealing surface, extending service life and reducing leak-related downtime.

Field technicians and equipment maintenance crews rely on replacement o-rings like this for emergency repairs, routine preventive maintenance, and system overhauls. Whether you operate mobile hydraulic systems, stationary industrial compressors, or marine-duty equipment, having the correct side bell o-ring on hand eliminates lead times and keeps operations moving. WINTERS is recognized in hydraulic markets for component consistency and compatibility across multi-rib configurations.

Stock this thin-profile o-ring as a critical spare part for any fleet or workshop that services side bell compressors. The WINTERS 7403T is sold as a single unit, making it easy to order exact quantities for kit assembly or individual replacement jobs.
