The Ashcroft 81 Bolt Thru Isolation Ring is engineered to safeguard measuring instruments, including pressure gauges, switches, and transducers, from direct exposure to process media. This innovative isolation ring features a 360-degree flexible liner that effectively prevents clogging or fouling, ensuring accurate hydraulic pressure transmission to the connected instruments.
Designed for installation between customer-supplied flanges in process piping, the Ashcroft 81 is available in nominal pipe sizes ranging from 1 to 10 inches. Its unique ring design minimizes the risk of process accumulation, thereby enhancing the reliability and precision of pressure measurements.
