PESIKO Compression Tester Kit 0–300 psi Gauge — Dual-Scale Aluminum Dial, Brass Adapters (12/14/18mm)

PESIKO Compression Tester Kit is a complete 0–300 psi diagnostic set that measures cylinder compression to reveal worn rings, leaking valves, or head gasket issues quickly and reliably.

This compact, workshop-ready kit pairs a dual-scale aluminum gauge with shockproof rubber protection and a selection of high-strength brass adapters to test most gasoline engines. Designed for professional mechanics and home enthusiasts, it combines durable construction, deep-reach hoses and a simple quick-connect system so you can take consistent readings even in tight spark-plug wells.

How does the gauge deliver accurate compression readings?

The PESIKO gauge uses a dual-scale (0–300 psi / 0–20.7 bar) dial with 5 psi resolution and an aluminum core to maintain precision. A shock-absorbing rubber boot and reinforced seals reduce the chance of physical damage and pressure loss, while brass fittings resist deformation under heat.

• 5 psi resolution on clear dual-scale dial for repeatable measurements
• Aluminum core for stable internal mechanics and long-term accuracy
• Shockproof rubber boot minimizes impact-related calibration changes
• Reinforced seals and brass fittings ensure airtight connections

Can I use this kit on different gasoline engines and tight access points?

Yes — the kit includes 12mm, 14mm and 18mm brass adapters that cover most Japanese, American and European spark plug sizes. The 26" hose plus three flexible rubber extensions and one metal tube let you reach recessed spark plug holes without compromising measurement integrity.

• Three adapter sizes fit a wide range of gasoline engines
• 26" main hose for extended reach to remote cylinders
• Flexible rubber tubes and metal tube tackle deep or angled spark plug wells
• Quick-connect fittings maintain airtight joins during swaps

What features make this kit durable for shop use?

Components are built from materials chosen to withstand heat, oil and vibration common in engine bays. High-strength brass resists corrosion and warping, while the aluminum gauge and rubber boot form a layered defense against drops and knocks.

• Brass fittings resist engine heat, oil exposure and corrosion
• Aluminum gauge core provides lightweight strength and stability
• Rubber boot adds impact protection and improves grip
• Reinforced seals reduce gas leakage for reliable results

How easy is the PESIKO kit to operate and maintain?

Operation is straightforward: screw in the correct adapter, crank the engine a few revolutions, then read the peak pressure on the dial. A one-touch pressure release quickly resets the gauge; the modular quick-connect system simplifies changing adapters and prevents leaks.

• One-touch release valve for fast reset between cylinders
• Quick-connect system for clean, leak-free swaps of adapters and tubes
• Compact storage case keeps parts organized and portable
• Simple cleaning and durable materials minimize maintenance needs

Who is this for: The PESIKO Compression Tester Kit suits mechanics, technicians and DIY car owners who need a rugged, accurate tool for engine diagnostics. If you troubleshoot gasoline engines—whether on daily drivers, project cars or small engines—and want consistent compression readings with equipment built to tolerate shop conditions, this kit provides the adapters, reach and protection required for repeatable results.
