This 10-pack of O-rings (part #HS500122) is manufactured from 218 Duro 70 Buna-N Nitrile material, specifically engineered for Hide-A-Hose mini-cuff applications. These replacement O-rings maintain the critical airtight seal between the hose cuff and central vacuum attachments in Hide-A-Hose retractable systems.

The high-grade Buna-N Nitrile construction provides superior resistance to ozone, petroleum products, and temperature extremes (-40°F to +250°F), while maintaining consistent flexibility throughout 10,000+ connection cycles. Each O-ring measures 0.875" outer diameter x 0.625" inner diameter with 0.125" cross-section thickness for precise mini-cuff fitment.

Direct replacement for both HS5000H4 SmartSoc cuff and HS5000H5 RapidFlex cuff assemblies. These mini-cuffs enable quick-connect attachment mounting directly to cleaning tools, making proper O-ring seal integrity essential for maintaining 120+ CFM airflow and preventing suction loss at connection points.
