HEAVY RETAINER NUT W/O-RING

A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.

O-rings are used in various types of restaurant equipment to create a seal between two connected parts, preventing leakage of product, liquids or gases:

• Espresso Machines: O-rings are used to seal the group head and the portafilter, ensuring that hot water and steam are directed into the coffee grounds to produce espresso, and not leaked out.
• Refrigeration Systems: O-rings are used to seal the refrigerant lines and connections in refrigeration systems, preventing refrigerant leakage and ensuring that the system operates efficiently.
• Beverage Dispensers: O-rings are used to seal the connections between the beverage dispenser and the beverage container, ensuring that the beverage is dispensed without any leakage.
• Dishwashers: O-rings are used in dishwasher pumps, ensuring that water is properly circulated and does not leak or flow in the wrong direction.
• Fryers: O-rings are used to seal the connections between the gas supply and the burner in fryers, ensuring that there is no gas leakage and preventing potential safety hazards.

A retainer is a mechanism that positions, as a device, frame, or groove that restrains, holds in place, or guides.  A retainer may be also be a clip, bracket, or similar component that prevents a part within a machine from moving.
