Bunn 7011 SIL018 Aftermarket O-Ring

Secure a professional-grade seal with the Bunn 7011 SIL018 Aftermarket O-Ring, specifically engineered to withstand the rigorous demands of high-volume commercial beverage systems. This Buna-N Nitrile 70 Durometer aftermarket part is a critical component for maintaining the integrity of swing spouts and liquid dispensing nozzles, effectively preventing the leaks and pressure drops that lead to costly service calls and equipment downtime.

Designed as a direct field replacement for the Bunn 07011.0000, this o-ring features a precision 5/8 inch ID and 3/32 inch width, ensuring an airtight fit in models such as the Bunn U3, SRU, and ES1AF. The black NBR material offers specialized resistance to petroleum-based lubricants and has an operational temperature range from -40°F to 250°F, making it the ideal choice for commercial coffee machine repair where thermal stability and chemical resilience are non-negotiable for leak-free dispenser performance.

• Precise Compatibility: Engineered for a seamless fit across major Bunn series including SRU, SRUA, U3, and ES1AF units.
• Industrial Resilience: High-tensile 70 Shore A hardness provides superior abrasion resistance and long-term elasticity for heavy-duty cycling.
• Fluid Compatibility: Optimized for water applications and resistant to common cleaning chemicals and scale-prevention lubricants.
• Fast Field Install: Standardized AS568 sizing enables rapid replacement during routine preventative maintenance or emergency repairs.

Common Questions

Will this o-ring stop a dripping spout in a Bunn U3 brewer?
Yes. In most cases, a slow drip from the swing spout is caused by a compromised 7011 o-ring. Replacing the worn seal restores the hydraulic seat, ensuring a clean shut-off.

Is the SIL018 material compatible with high-temperature beverage service?
Absolutely. The Nitrile (Buna-N) compound is rated for continuous operation at temperatures up to 250°F, which exceeds the standard brewing and holding temperatures of commercial coffee systems.

Do I need to lubricate this o-ring before installation?
Applying a light coating of food-grade silicone lubricant is recommended to prevent binding and ensure a proper seat during the assembly of the nozzle or spout components.
