Bunn 48895 Viton O-ring 113 Upper Piston

Product Description

The BUNN 48895 is a Viton O-ring, size 113, used as a sealing component on the upper piston assembly in BUNN commercial beverage equipment. Viton material is selected for its resistance to heat, steam, and the chemical exposure common in commercial brewing and dispensing environments. This O-ring maintains a reliable seal at the upper piston to prevent fluid bypass and ensure consistent equipment operation. Installation is performed by qualified service technicians during routine maintenance or piston assembly rebuilds.

This O-ring is intended for use in BUNN commercial appliances where upper piston sealing is required. It is a direct OEM replacement part, making it appropriate for service calls, scheduled preventive maintenance, and equipment rebuilds in commercial foodservice settings such as restaurants, convenience stores, and institutional kitchens.

Key Features

• Viton material offers strong resistance to heat, steam, and chemical degradation
• Size 113 O-ring for precise fitment at the upper piston assembly
• OEM replacement part sourced directly from BUNN
• Maintains fluid seal integrity to support consistent equipment performance

Compatibility

Installation Notes

Installation should be performed by a qualified commercial appliance service technician. Always disconnect power and relieve any internal pressure from the unit before disassembling the piston assembly. Inspect the seating surface for wear or debris before installing the new O-ring. Avoid using petroleum-based lubricants on Viton seals, as they can cause material degradation.
