What haygor instrument & company does

Haygor Instrument & Company, Inc. is a privately held Texas corporation founded in 1973 and headquartered in Pasadena, Texas, that designs, manufactures, and services industrial diaphragm seals and related pressure-instrumentation accessories. With 11-50 employees and US-only operations, the company focuses on four primary verticals: petro-chemical, oil & gas, medical, and cryogenic industries. The product line spans 18 specialized diaphragm seal configurations—including threaded, flanged, sanitary, chemical tee, pulp and paper, submersible, button, and flow-through variants—plus accessories such as calibration rings, bleed rings, and cooling towers. Haygor also offers complementary services including NIST-traceable calibration, ultrasonic and specialty gas-service cleaning (oxygen, nitrogen, chlorine, ethylene oxide), pickling and passivation, CNC and manual machining, and repair/remanufacturing of gauges, transmitters, controllers, chart recorders, and Honeywell DCS systems.

The firm's technology base is anchored by two granted patents. The Temperature Compensating Remote Seal system uses additional compensating capillary tubes to eliminate differential pressure transmitter drift caused by ambient temperature fluctuations, removing the need for heat tracing. The Thermal Guardian Diaphragm Seal employs a proprietary liquid metal alloy fill, including Galinstan, combined with cooling fins to enable continuous pressure measurement at temperatures up to 1200°F (650°C)—well above the industry-standard 850°F ceiling. Haygor holds ISO 9001:2015, 3A Sanitary, and RPSCQC certifications, and maintains REACH, RoHS, and Conflict Minerals compliance posture for export-facing customers.

Revenue is generated through a sales-led, direct distribution model with quote-based pricing, phone-based sales (713-641-1791), website quote-request forms, and an emerging self-service configurator channel across the SKU range. Standard delivery is five days with a 24-hour emergency service tier. The company states it works with major instrument-manufacturer brands including Rosemount, Micro Motion, Azbil, Endress+Hauser, Honeywell, Yokogawa, SMAR, Ashcroft, Fisher, Cameron, and Siemens, indicating OEM-level or co-specified supply relationships within industrial process-instrumentation channels. Revenue mechanics combine hardware sales (diaphragm seals and accessories) with professional services (calibration, cleaning, repair, and machining), though no revenue, contract value, or shipment volume is publicly disclosed.

Core offering

Haygor Instrument & Company manufactures a comprehensive line of U.S.-made diaphragm seals across 18 specialized configurations (threaded, flanged, sanitary, chemical tee, pulp & paper, submersible, button, flow-thru, etc.) and sells two patented proprietary products — Temperature Compensating Remote Seals and the Thermal Guardian™ Diaphragm Seal — to protect pressure instruments in extreme temperature and harsh process environments. The company complements this hardware with repair/remanufacturing, NIST-traceable calibration, precision cleaning for oxygen/nitrogen/chlorine/ethylene oxide service, pickling and passivation, CNC and manual machining, and valve and actuator parts for petro-chemical, oil & gas, medical, and cryogenic customers.

Product overview

Haygor Instrument & Company offers a comprehensive portfolio of industrial instrumentation products and services primarily serving the petro-chemical, oil & gas, medical, and cryogenic industries since 1973. The core product line centers on diaphragm seals—including 18 specialized variants (Threaded Seals, Flush Seals, Flanged Seals, Sanitary Seals, Chemical Tee/Wedge Seals, Pulp and Paper Seals, Submersible Seals, Button Seals, Annular Flow-Thru Seals, Calibration/Flushing Rings, Bleed Rings, Flow Thru In-line Seals, Cooling Towers, and System Attachment/Fill components)—alongside proprietary patented technologies like the Thermal Guardian™ (capable of 1200°F/650°C operation) and Temperature Compensating Remote Seals (which eliminate drift through compensating capillary technology). The company also provides complementary services including precision cleaning for various gas services (oxygen, nitrogen, ethylene oxide, chlorine), ultrasonic cleaning, pickling/passivation, NIST-traceable calibration, CNC and manual machining, and repair services for gauges, transmitters, controllers, chart recorders, and filled systems.
