I have several (7 or 8) NEW and unused 2_3/8" (60mm) diam pressure gauges, marked 0 to 160psi, plus 0 to 11 bar. These were for a project that never happened and are now surplus to my requirements. The entry is 1//4" BSP at the bottom. £5 each, or make an offer if you want several. They would be ideal for pressure testing (if you only run at 80psi, and want to test at 2x WP) or 100psi if you test at 1.5xWP. Alan MODEL ENGINEERING DISCUSSION LIST.
