Q: Does this manifold set require swapping parts when switching between R12 and R134a refrigerants?
A: No, the set includes separate hoses and manual couplers for both R12 and R134a ports so you can service either refrigerant without changing parts; make sure to use the correct hose and coupler for the refrigerant being handled.

Q: What is the length of the hoses included?
A: The kit includes six hoses total: three R134a rated hoses and three R12 rated hoses, each 60 inch in length.

Q: Is the 3-in-1 can tap valve compatible with standard A/C cans?
A: Yes, the 3-in-1 side-mount can tap valve is designed to connect to standard service cans used for charging or topping off refrigerant; it works as a bridge between manifold and can while maintaining safety and control.
