Comec VPT190 Pressure Tester for Cylinder Heads and Blocks

The Comec VPT190 is a heavy-duty, immersion-type pressure testing machine engineered to locate cracks, leaks, and structural defects in cylinder heads and engine blocks. It immerses the head/block in a heated, insulated stainless-steel tank and pressurizes the internal coolant/ water-jacket passages. Any air escaping through cracks or porosity becomes visible as bubbles, making even small leaks easy to detect.

 

Compared to smaller testers, the VPT190 significantly expands capacity — enabling shops to test very large heads or blocks including heavy-duty or industrial-engine castings. The machine combines a high-capacity tank, fully insulated build, programmable heating, and a rotating cradle to inspect parts thoroughly — ideal for a professional engine-rebuild shop aiming for quality assurance.

Key Features

  • Large Capacity for Big Heads & Blocks — Accepts parts up to 1350 × 460 × 410 mm, covering many large automotive, light-truck, and diesel or industrial engine heads/blocks.
  • Large-Volume Insulated Stainless-Steel Tank — ~ 710 L tank with full insulation helps retain heat, prevent corrosion, and minimize energy loss.
  • Dual 4.5 kW Heating Elements + Programmable Timer & Touch-Screen Controls — Allows water temperature control (typically 30–90 °C) with automated heating cycles for efficiency and consistency.
  • Hydraulic Cradle with 360° Rotation & Vertical Lift — Cradle strokes 550 mm vertically, rotates at 4 rpm, and lifts/drops at 60 mm/sec — facilitating full immersion and inspection of any surface area or casting geometry.
  • Comprehensive Standard Accessory Kit — Includes support parallels (flat & angled), plexiglass closure plates, rubber gasket sheets, tension rods, locking plates and fasteners — enabling sealing and testing of many head/block types without custom fixtures.
  • Built for Professional Use / Heavy Duty Engine Work — Because of its size, high-power heating and robust build, the VPT190 is ideal for shops doing regular block/head reconditioning—including industrial, heavy-duty or large-bore engines.

Built on Real Engine-Rebuilding Experience

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.

A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.

Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
