Return Line Connection: Flow Capacity 20-100 L/min

Component Specifications

Definition

A specialized fluid system component designed to connect the return line from machine tools or cooling systems back to the coolant reservoir or tank, ensuring proper flow direction, pressure management, and leak prevention in industrial cooling circuits

Working Principle

Operates by providing a sealed interface between the return piping and the coolant reservoir, utilizing mechanical fastening and sealing mechanisms to maintain system integrity while allowing for thermal expansion and vibration absorption in industrial environments

Materials

Stainless steel (AISI 304/316), brass, or engineered polymers (PTFE, Nylon) with corrosion-resistant properties and compatibility with industrial coolants
