IntXanth Valve Air Cylinder Head Vacuum Leak Detector
The IntXanth unit emphasizes portability and ease of use. It weighs only 9.3 lbs, features a portable handle, and a single-person operation design. The control panel is centrally placed for convenient use, with an input positive pressure gauge and an output negative pressure gauge to track test results clearly.

It’s best for HVAC technicians and automotive A/C specialists who need a robust, ready-to-use set for quick leak testing of systems and seals. A potential drawback is that the kit’s compatibility relies on the user’s existing vacuum pump and connectors; verify fit before purchasing.

Buying Guide
Key considerations when choosing a cylinder head vacuum tester:
- Compatibility: Ensure the tester fits the valve-seat patterns and cylinder head brands you routinely service (Goodson, Sioux, Redis, Van Norman, etc.).
- Portability vs. stability: Lightweight models offer mobility; heavier kits may provide more accessories and stability for repeated use.
- Pressure range and gauges: Look for clear, easy-to-read gauges and a suitable pressure range for engine testing purposes (vacuum and low-pressure positive measurements).
- Fittings and adapters: Confirm brass fittings and included adapters are compatible with your test benches, vacuum pumps, and hoses.
- Durability: Durable construction reduces wear in busy shops and improves long-term reliability.
- Ease of use: A straightforward control panel or manual operation can shorten setup time, especially for field work.
- Maintenance: Consider how easy it is to clean, recalibrate, and store the unit when not in use.
