Frequently Asked Questions:

Q. Are vacuum hoses universal?

A. Yes, vacuum systems feature outlet holes that measure 2.5 inches in diameter. The screw-on fittings on these vacuum hoses can be easily installed on 2.5-inch holes.

Q. What are manifold gauges?

A. These gauges are used with vacuum hoses while recharging or repairing cooling systems. The vacuum hoses connect these gauges with the HVAC system to check both high & low refrigerant pressure for leak detection, measuring refrigerant volume and troubleshooting tasks.

Q. What are low-loss fittings?

A. These low-loss, anti-blowback fittings are used on Yellow Jacket vacuum hoses to trap refrigerant inside the hose when disconnected. It prevents finger burns and the release of toxic refrigerants into the atmosphere.

Q. Why are charging hoses angled?

A. These hoses have angled fittings to enable connection in tight spaces. Angled tips are ideal for both recharging and maintenance tasks.

Q. How to check vacuum hoses?

A. Users must check for small tears and cracks at hose ends. The fitting's internal threads should be examined for wear and the hose should be checked for bulges indicating torn internal layers.
