Universal Radiator Adapter
The Mityvac MV4508 universal radiator adapter connects coolant bottle necks and radiators during cooling system service. Its rubber construction fits a wide range of vehicle makes and models. Technicians and DIY owners use it to simplify fluid changes and pressure testing on passenger cars and light trucks.
Rubber Construction Limits
The rubber material provides a flexible seal but is not rated for extreme heat or chemical exposure beyond standard automotive coolant. It suits routine maintenance tasks rather than continuous high-pressure circulation. Users should verify the neck diameter matches the adapter before each use to prevent leaks.
Replaces Makeshift Seals
This adapter replaces improvised plugs, clamps or ill-fitting caps that risk coolant spills and air pockets. The jump is worth it when a secure, repeatable connection saves time on flushing, refilling or pressure checks. It is not for builders who need a second adapter for simultaneous dual-circuit work.

Questions about this item
Which Mityvac MV4508 adapter version suits my cooling-system service?
The MV4508 is a single universal radiator adapter designed to fit coolant bottle necks and radiators across all vehicle makes, models and years, supplied as one rubber piece in black and yellow.
What does the universal fit claim mean when I use the adapter on my car?
It connects to standard coolant bottle necks and radiator openings without needing model-specific parts, letting you pressure-test or flush the cooling system on virtually any vehicle.
How does the rubber construction affect the seal on pressurised cooling systems?
The rubber body conforms to neck and radiator surfaces, creating a tight seal that holds pressure during testing and flushing without damaging plastic or metal fittings.
