Product Description
Ashcroft Manufacturing / Ashcroft Instruments (Stratford, Connecticut) — operated for much of the asbestos era as the Ashcroft Industrial Division of Dresser Industries before later divestiture — manufactured the industry-standard Bourdon-tube industrial pressure gauge along with diaphragm and chemical seals, temperature gauges, pressure switches, and test-gauge assemblies for industrial steam, refinery process, power-plant auxiliary, and shipboard service.
Ashcroft gauges and diaphragm seals were installed in overwhelming volume across process and utility piping — boiler drums, steam headers, pump discharges, refinery process runs, and shipboard steam-plant instrument lines — and are frequently identified in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.
Plaintiffs alleged that Ashcroft instrumentation was specified with:
- Compressed asbestos-sheet gaskets at the gauge-socket / instrument-line union, disturbed each time a gauge was removed for calibration, repair, or replacement.
- Compressed asbestos-sheet gaskets at the flanged joint of Ashcroft diaphragm seals and chemical seals used to isolate the Bourdon tube from hot, corrosive, or slurry process fluids.
- Asbestos-containing thermal insulation applied to hot instrument-line runs and gauge-siphon assemblies on high-temperature steam service.

If You Worked With Ashcroft Gauges and Diaphragm Seals
If you installed, calibrated, or replaced Ashcroft Instruments Bourdon-tube gauges, diaphragm seals, or pressure switches during the asbestos era — and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related illness — you may have legal rights.
