Metal Upgrade Options for Cooling System Components
For select coolant-related components, Rein offers both OE-style plastic versions and upgraded metal alternatives. Each option is engineered to meet OE specifications for fit and function. The availability of both materials supports flexibility in service approach, vehicle use, and operating conditions.
Plastic or Metal: Why Offer Both?
Plastic remains a standard material across many OE cooling systems due to its precision molding, weight advantages, and cost efficiency. In some environments, however, a metal version may offer greater resistance to thermal cycling, mechanical stress, or chemical exposure.
Rein supports both construction types in many parts to accommodate different application needs.
