AUTOOL Conical Adapter Fittings Use for SC301 Cooling System Tester Accessory

The AUTOOL SC301 conical adapter fitting set is an accessory for compatible AUTOOL SC301 cooling-system testing and filling work. Three tapered rubber adapters in 33 mm, 41 mm and 52 mm sizes help seal different radiator or coolant reservoir openings. Confirm the opening size and SC301 connection before use. Use the three tapered adapters to match different cooling-system filler necks during compatible SC301 pressure testing, vacuum filling or coolant service. Select the size that forms a stable seal without forcing the adapter. The product image identifies three tapered adapter sizes. Use the adapter that matches the cooling-system opening and creates a stable seal. This accessory set is intended for compatible SC301 cooling-system service and is not a complete tester or filler by itself. Because this accessory is used on cooling systems, allow the engine to cool and choose the correct adapter size before applying pressure or vacuum. For adapter size, SC301 compatibility and vehicle cooling-system fit confirmation, contact AUTOOL Store support before ordering or use.
