The Ashcroft 80 Wafer Isolation Ring provides reliable pressure instrument protection in applications that require continuous pressure measurement. Its wafer-style design mounts inline with process piping and helps reduce process buildup around the measurement point. As a result, operators can maintain more accurate pressure readings while reducing maintenance concerns caused by clogging or material accumulation.
The Ashcroft 80 wafer isolation ring suits demanding water, wastewater, and mining applications. It supports nominal pipe sizes from 2″ to 20″ and offers several material combinations for wetted and non-wetted components. These options help match the isolation ring to the process media, piping requirements, and instrumentation needs.
Westech Industrial supplies the Ashcroft 80 isolation ring in Alberta and Saskatchewan. Our team can help with product selection, sizing, instrument compatibility, and service support. Westech also provides custom fabrication capabilities for related instrumentation assemblies, panels, and process measurement packages.

Description
Inline Protection for Pressure Instruments
The Ashcroft 80 Wafer Isolation Ring helps protect pressure instruments from process media. Instead of exposing the instrument directly to the process, the ring uses a flexible liner and fill fluid to transfer pressure. This design helps keep solids, slurry, and other challenging media away from the pressure instrument. Therefore, the gauge, switch, or transmitter can perform with greater reliability in difficult applications.
Non-Clogging, Low-Maintenance Design
Process buildup can cause inaccurate pressure readings and extra maintenance. The Ashcroft 80 Wafer Isolation Ring addresses this problem with a ring-style design that reduces accumulation at the sensing point. This makes it a strong choice for continuous pressure measurement in water, wastewater, and mining applications. In addition, the low-maintenance design helps reduce downtime and supports dependable operation in process piping systems.
Size and Material Flexibility
The Ashcroft 80 Wafer Isolation Ring supports nominal pipe sizes from 2″ to 20″. This range gives facilities flexibility when matching the ring to existing process piping. It also offers several end plate and liner material options. Wetted end plate materials include carbon steel, 316L stainless steel, PVDF, acetal, and CPVC. Flexible liner options include Buna-N, PTFE, EPDM, natural rubber, and Viton™. These options allow users to select materials based on media compatibility and temperature requirements.
Instrument Connection and Removal Options
The Ashcroft 80 Wafer Isolation ring supports ¼” and ½” NPT instrument connections. It also offers several instrument mounting and removal options, including direct mount, needle valve, Safe Quick Release, and needle valve with Safe Quick Release. With the SQR™ option, operators gain 360° instrument rotation, which helps with readability and positioning. This can make installation and maintenance easier in tight or awkward locations.
Retrofit and Assembly Options
The Ashcroft 80 Wafer Isolation Ring can include optional retrofit end plates for drop-in replacement of competitive units. It also offers multiple instrument assembly options, including gauge and transducer combinations or gauge and switch combinations. For vertical pipe installations, an elbow option can also support proper orientation. These options give users more flexibility when upgrading existing pressure measurement points.
NSF-61 Compliant Configuration
For applications that require NSF-61 compliance, the Ashcroft 80 Wafer Isolation Ring offers a compliant configuration with 316L stainless steel and EPDM. This option supports use in qualifying water-related applications where material approvals matter.
Applications
The Ashcroft 80 Wafer Isolation Ring supports continuous pressure measurement where process buildup, clogging, or media exposure can affect instrument performance. It works well in applications that need reliable readings and instrument protection.
