28mm 1/8BSP Thread Paintball Gauge 3 Units - Adjustable Bar/Psi/Mpa

In this review of the 28mm 1/8BSP Thread Paintball Gauge from Pautaca, the bottom line is that this compact digital manometer is a practical, budget-friendly option for PCP and paintball players who need a clear, adjustable pressure readout. The gauge's main appeal is the easy-to-read backlit display and selectable units (Bar, psi, Mpa), which make quick checks on tanks, hand pumps or compressors straightforward. It is small, protected by a rubber cover, and runs on a CR2032 cell for simple field swaps.

Key Features

• 28mm diameter with 1/8" BSP thread: Provides a compact fit for common PCP charging valves and regulator ports so it can replace similar WIKA or SEKHMET style gauges.
• Adjustable units: Default display is in Bar but can be switched easily to psi or Mpa to match regional preferences or equipment markings.
• Wide pressure range: Reads 0 to 400 Bar (6000 psi / 40 Mpa), covering typical paintball and high pressure airgun needs for charging and testing.
• Backlit digital display: The clear readout is easy to see in low light, which is handy for range or field use.
• Battery powered CR2032: Uses a common 3 V button cell with two access holes for straightforward replacement without special tools.
• Protective rubber cover: Copper alloy body with a rubber case helps protect the gauge and prevent the battery from falling out during use.

Who It's For

This gauge is aimed at shooting enthusiasts, paintball players and hobbyists who need a compact, accurate pressure checker for PCP airguns, hand pumps and portable compressors. Its small 28mm face and 1/8" BSP thread make it suitable for direct fitting to many charging valves and test ports.

Those who need USB-rechargeable electronics, a larger dial, or integrated hose assemblies should look elsewhere; this model is a basic inline replacement or accessory gauge rather than a complete charging station. Also check thread type and diameter before buying to ensure compatibility with your equipment.

Pros & Cons

Pros

• Compact 28mm size and standard 1/8" BSP thread fit many PCP valves and regulators.
• Selectable Bar/psi/Mpa units and wide 0-400 Bar range suit varied equipment and regions.
• Clear backlight display and rubber cover improve readability and durability in the field.
• Uses a common CR2032 battery with simple removal holes for easy replacement.

Cons

• Runs on a CR2032 cell rather than USB recharge, so you will need spare batteries for extended use.
• The small 28mm face may be harder to read at a distance compared with larger gauges.
