Vacuum Gauge -1/0 Bar | 1/4 in NPT Back
Aftermarket Vacuum Gauge -1/0 Bar | 1/4 in NPT Back Aftermarket Vacuum Gauge -1/0 Bar | 1/4 in NPT Back is a liquid-filled industrial vacuum gauge selected as an aftermarket rear-connection option for verified dry-cleaning still and distillation vacuum-gauge service. This listing is intended for customers whose installed gauge matches the FMB / Firbimatic 0804011 style vacuum range but uses a center-back / rear connection instead of a lower bottom connection. It is not an OEM FMB, Firbimatic, Union, Realstar, or Sovrana part. It should be ordered only after confirming the installed gauge range, connection size, thread type, connection location, dial clearance, and machine/service-manual path. Technical Specifications Component type: industrial vacuum gauge / rear-connection replacement option Gauge range: 30 in Hg to 0 Secondary range: -1 to 0 bar Connection size: 1/4 in Connection type: NPT Connection gender: male Connection location: center back / rear Nominal dial size: 2 1/2 in Case diameter reference: about 2.65 in Case depth reference: about 1.21 in Case material: stainless steel Lens material: polycarbonate Socket / sensor / wetted material: copper alloy / copper Fill liquid: glycerin / liquid-filled case Vibration resistance: liquid-filled Accuracy: +/-2-1-2% Accuracy grade: ASME B40.100 Grade A Scale type: dual scale Includes: vent plug Calibration certificate: not included Oxygen service: not cleaned for oxygen service Hazardous-location rating: not rated Operating temperature reference: ambient -30 F to 180 F; process media 30 F to 160 F Aftermarket Replacement Notes This is an aftermarket industrial replacement option selected for cases where the installed gauge uses a center-back/rear connection. It should not replace a bottom-connection gauge unless the machine plumbing and panel layout are intentionally being adapted by a qualified technician after verifying clearance, fittings, and service requirements. The liquid-filled/glycerin construction can help damp pointer movement in equipment areas where vibration or pulsation is present. The stainless case and polycarbonate lens make it a practical service replacement when the installed component specifications match. This is not an OEM Firbimatic/FMB gauge and should not be treated as a universal replacement. Rear-connection gauges are more sensitive to panel depth, fitting clearance, and line alignment, so customers should confirm the rear thread location and available space before ordering. Part Numbers & Cross References Corbett Equipment CE-GAU-VAC-254A-BACK Compare Against FMB / Firbimatic 0804011 rear/center-back option Omnia / F60K gauge-plate reference lane: Tavola RC1271_A Aftermarket replacement option only where the installed component and service requirements support this gauge configuration Related Parts To Verify Separately Bottom/lower connection gauges should be ordered when the installed gauge uses a lower connection. 0804009 / A15572 is a separate vacuum/pressure manometer lane with positive pressure range and should not be replaced with this vacuum-only gauge. Pressure-only gauges should not be used where vacuum indication is required. Machine Fitment Master Manufacturer / Model Lineage Use this aftermarket gauge only as a verified replacement candidate for machines whose installed gauge matches the source gauge lane, connection location, range, and service requirements. Corbett Equipment treats FMB / Firbimatic as the master builder lineage, with Union, Realstar, and other sister/derivative families researched from model-lineage evidence and verified against the installed component. FMB / Firbimatic Machine Models And Master Families Potential reference families include Omnia / F60K, EcoGreen, EcoGreen SM / AM-prefix machines, EcoPro / ECOPRO, Saver, EcoLine, F-series machines, 9 Series KWL / PERC, Vortex, Axial, Petite, Nevada, Hydro-Vac, Hydro-Chill, Tri-Flow, Smart-10, SecureLock, and recovered numeric FMB / Firbimatic model families where the installed gauge range, connection, mounting, and service-manual path confirm this gauge lane. Union Machine Models And Derivative Families Union derivative references may include HXP8018C, L840, P840, HL / HP / HXL families, HL-780, HL-840, HL-850, HL-860, HL-880, HL-890, L740S, L740, HL740, L750, RS-102, RS-122, and RS-152 where the installed gauge and service documentation confirm the same range and connection requirements. Realstar Machine Models And Derivative Families Realstar derivative references may include KM / KT and RKM families such as KM315, KM343, KM403, KM503, KM703, KM803, KT215, KT343, KT403, KT503, RKM36, RKM340, and RKM400 where the installed gauge and service documentation confirm the same range and connection requirements. Sovrana And Other Derivative References Treat Sovrana and other derivative references as verification-required lanes unless the installed machine data plate, manual, or removed gauge confirms the exact gauge range, connection size, and connection location. Manual / Gauge-Plate Source Reference Omnia / F60K Tavola RC1271_A shows the OEM gauge family used for comparison and verification. Ordering Verification Before ordering, compare the installed gauge to this listing: gauge range and units vacuum-only versus compound vacuum/pressure function 1/4 in NPT male thread center-back/rear connection location dial diameter, panel depth, and rear fitting clearance service temperature and process media machine model and data plate service manual or exploded-view reference photos of the removed or installed gauge Warnings & Restrictions Not an OEM Firbimatic/FMB part. Not cleaned for oxygen service. Not hazardous-location rated. Calibration certificate not included. Prop 65 warning should be reviewed against final product evidence when the purchasing path or manufacturer data changes.
