Temperature
Compensating Seals

Haygor’s patented remote seal system uses an additional set of capillaries to counteract temperature-induced pressure changes in standard lines. This design minimizes measurement drift and stabilizes differential pressure readings across changing ambient conditions.

Thermal Guardian
Diaphragm Seal

The Thermal Guardian enables accurate pressure readings in extreme temperatures up to 1200°F (650°C). Its patented configuration dissipates heat before it reaches the pressure instrument, protecting internal components while preserving measurement reliability.

Diaphragm Seals

Haygor offers a broad selection of diaphragm seals tailored to diverse process conditions. Whether for general industrial use or specialized service, their designs ensure long-term reliability and accurate pressure transmission in demanding environments.
