Universal Cooling System Pressure Test Kit, No. 6977

The OTC Universal Cooling System Pressure Test Kit, No. 6977, is designed for a faster evaluation with a universal approach by eliminating the search for the right cap adapter. The hand pump features an easy-to-read pressure gauge with a padded base to prevent vehicle scratches, and a 36" pressure hose with quick-connect. The hose adapters use brass fittings for increased durability and includes a banded spring clamp for easy attachment. Each of the four adapters include a Schrader valve to prevent spray when disconnecting and come in four sizes: 1/4", 5/16", 1/2" and 5/8" in diameter.
