BETOOLL Compression Tester Kit HW0130 — 8‑Piece Petrol Engine Tester with 3" Dual-Scale Gauge & 17.7" Hose

BETOOLL HW0130 is an 8-piece petrol engine compression tester kit with a dual-scale 3" gauge and multiple adapters for fast, accurate cylinder compression checks.

Diagnosing cylinder sealing and engine health begins with a reliable compression test. The BETOOLL HW0130 kit combines a clear analog gauge, a long flexible hose, and a set of adapters and cones so you can test a wide range of petrol engines — from motorcycles and cars to ATVs and small trucks — without complicated tools or extensive teardown.

How quickly can I check engine compression with this kit?

The tester is designed for fast setup and readout so you can get meaningful results in minutes. The 17.7" extension hose and selectable adapters let you connect to spark plug holes or use the rubber cone ends for non-threaded checks. A built-in pressure release button simplifies resetting between cylinders.

• 3" analog gauge with dual scale (0–300 psi and 0–20 bar) for immediate readings
• 17.7" flexible hose to reach recessed spark plug locations
• Quick-change adapters (10mm, 12mm, 14mm, 18mm) for most petrol engines
• Two rubber cone ends for fast, non-threaded compression checks
• Side-mounted pressure release button for safe, one-handed operation

What engines and vehicles is the BETOOLL HW0130 compatible with?

This kit is built for petrol-fired engines across a broad range of vehicles. The included adapter sizes cover common spark plug threads found on motorcycles, cars, ATVs and light trucks, while the rubber cones allow testing in spark plug wells or irregular ports. It’s not intended for diesel engines unless an appropriate adapter and procedure are confirmed.

• Motorcycles, scooters, ATVs and UTVs
• Passenger cars and light trucks with petrol engines
• Small engines where spark plug or port access is available
• Not marketed for diesel applications without separate adapters

How accurate and easy to read are the measurements?

The large 3" gauge features a dual-color scale to help you read results quickly under workshop lighting. The gauge range up to 300 psi (0–20 bar) covers typical petrol engine compression values, and the mechanical needle gives an immediate analogue indication of peak pressure. For repeatable results, follow standard test steps — warm engine, throttle open, and a stable cranking speed.

• Clear 3" dial with color-coded ranges for rapid interpretation
• 0–300 psi (0–20 bar) scale suitable for petrol engines
• Mechanical needle avoids battery dependence and electronic lag
• Pressure release valve for controlled, accurate resets

What’s included in the 8-piece kit and how is it used?

The kit supplies everything needed for most routine compression tests: the gauge assembly, a long hose, multiple threaded adapters, and cone attachments for non-threaded checks. Installation is straightforward — remove the spark plug, attach the correct adapter or cone, run the engine through several compression strokes, and record the peak. Clean and store components after use to preserve seals and hose flexibility.

• One 3" dual-scale gauge with pressure release button
• 17.7" extension hose for reach and flexibility
• Four selectable threaded adapters: 10mm, 12mm, 14mm, 18mm
• Two rubber cone ends for quick, non-threaded checks

Who is this for? The BETOOLL HW0130 is aimed at DIY mechanics, motorcycle and car enthusiasts, and professional technicians who need a portable, easy-to-use compression tester for petrol engines. It’s helpful for pre-purchase inspections, troubleshooting misfires or oil consumption concerns, and routine engine health checks — all without requiring complex disassembly.
