What is the primary function of push nipples?

The primary function of push nipples is to connect radiator sections together. Push nipples are specifically designed to join various components of a radiator, ensuring a secure and effective connection. This function is crucial for maintaining the integrity of the heating unit, allowing it to operate efficiently without leaks.

Push nipples accomplish this by creating a tight fitting between the radiator sections, often facilitating a smooth flow of liquid (typically water or a water-glycol mixture) for heating purposes. Their design might vary, but the essential purpose remains focused on the interconnection of radiator parts, contributing to the overall functionality of the system.
