IBHS Ltd offers a comprehensive selection of 4" (100mm) boiler pressure gauges, providing a compact and easy-to-read solution for a wide range of boiler and pressurised system applications. Available in brass dial, steel dial and front flange configurations, with pressure ranges from 0-30 psi/bar through to 0-1,000 psi/bar, the range provides options to suit a variety of professional installation and replacement requirements.

The 4" gauges are available with 3/8" BSP bottom connections across the brass and steel dial variants, while the front flange models feature a 3/8" BSP back connection for panel-mounted installations.
