The Imperial 680CKPSC is a trade-grade 4-valve manifold built for techs who want fast evacuation and reliable readings on R22, R134a and R404A systems. It’s tough, accurate, and built to cop jobsite abuse—fair dinkum performance that helps you finish quicker and get paid sooner.

Key Features & Trade Benefits

• 3/8" Vacuum Port & Oversize Passages — Move more vapour, hit target microns faster, and shave minutes off every pull-down. Less waiting, fewer call-backs.
• Four Independent Valves — Low, high, vacuum and refrigerant lines stay connected. No swapping hoses mid-job, which keeps things cleaner and quicker.
• Diaphragm-Type Soft-Seat Valves — Fingertip pressure to seal; one turn open/close. Control you can feel, even with gloves on.
• Precision, Colour-Coded Gauges — Easy to read and built to resist shock and pulsation. Consistent, trustworthy readings when you need them.
• Ergonomic, Non-Slip Handles — Confident grip with oily fingers, in the shed or on the roof.
• Swivel Hanger — Hang it up where you can see it and work hands-free. Too easy.

Why This Product Matters

When you’re on a Sydney roof in summer or squeezing into a tight plant room in Brisbane, speed and accuracy matter. The 680CKPSC’s 3/8" vac port gives you a proper highway for vapour removal, so you reach deep vacuum faster and move on to charging without mucking about. One of our regulars reckons after switching to this body, he saved a bloody good chunk of time on every evac—enough to squeeze in another service call before knock-off.

Pro Tip

Pair your 3/8" vac port with a dedicated 3/8" vacuum hose and a micron gauge at the system port for true readings. A simple combo like the SVG3 Digital Micron Gauge takes the guesswork out and helps avoid “almost there” vacuums that turn into call-backs.
