Ashcroft 351009SW04L1000#
4" Stainless Steel Bourdon Tube Pressure Gauge, 0-1000 psi, 1/2" NPT LM, Dual Scale
Ashcroft 1009 Duralife, 3½ in (100 mm) dial, all-welded 304 stainless steel case with a removable bayonet ring and polycarbonate window, 1/2 in male NPT lower connection, supplied dry and field fillable with glycerine for vibration-prone installations, 0-1000 psi, accuracy ±1% of span dry (ASME B40.100 Grade 1A, equivalent to EN 837-1 class 1.0), IP65 with the fill plug closed. Ashcroft lists pumps and compressors and hydraulics and pneumatics among its typical uses, which is this gauge's duty. Differences from the WIKA 212.53.100 that this entry cross-references, so you can judge the swap: the Ashcroft dial is single-scale psi, and the 1009 range table lists no bar equivalent at all at 1000 psi, so the red bar second scale on the WIKA has no catalogue equivalent; the wetted parts are a 316 stainless steel Bourdon tube with a 316L stainless steel process connection, not brass or copper alloy, because the 1009 aluminium and bronze system cannot be ordered with a 1/2 in NPT connection; the case ring is a removable bayonet rather than a crimp ring; and the case is 98.8 mm across against 107 mm on the WIKA, so panel cut-outs and U-clamp mountings are not interchangeable. Ashcroft rates continuous service at 75% of span, that is 750 psi, with proof pressure 110% of span above 600 psi, where the WIKA is rated for steady service at full scale and 1.3 times full scale short-time.
