The Ashcroft 82 Threaded Isolation Ring protects pressure measuring instruments in threaded piping systems. It threads in-line with process piping and helps prevent clogging from process media. As a result, it supports accurate pressure readings and helps reduce maintenance around the measurement point.
The ring-style, flow-through design helps eliminate process accumulation. This makes the Ashcroft 82 a practical choice for applications that handle water, wastewater, mining slurries, pulp and paper processes, and chemicals. It also offers an economical design, short lead times, and multiple material options.
Westech Industrial offers the Ashcroft 82 threaded isolation ring in Alberta and Saskatchewan. Our team can help with product selection, pressure measurement requirements, instrument connection options, and related service support. Westech can also assist with custom fabrication when your project requires integrated assemblies, panels, enclosures, or site-specific installation support.

Description
Non-Clogging Flow-Through Design
The Ashcroft 82 threaded isolation ring uses a low-maintenance flow-through design. This design helps reduce process build-up inside the ring. In turn, it helps protect connected pressure instruments from clogging. The threaded isolation ring also supports reliable readings by keeping process media away from sensitive instrument components.
This feature matters in applications where solids, fibres, or heavy process fluids can affect pressure measurement. Water and wastewater facilities, pulp and paper plants, mining operations, and chemical processes often need added instrument protection. The Ashcroft 82 gives these applications a simple way to protect pressure gauges and other pressure instruments.
Threaded Process Connections
The Ashcroft 82 suits threaded piping systems. Process connection sizes run from 1/2 NPT through 2 NPT. Therefore, teams can match the isolation ring to common threaded pipe sizes without adding unnecessary complexity.
The product also offers 1/4 NPT or 1/2 NPT female instrument connections. This allows the ring to attach to a variety of pressure instruments. It also gives maintenance and project teams more flexibility when they select gauges or other pressure measurement devices.
Material and Liner Options
The Ashcroft 82 threaded isolation ring offers several wetted material choices. End plate options include carbon steel, 316L stainless steel, and PVDF. Flexible liner options include Buna-N, EPDM, natural rubber, Viton™, and PTFE. PTFE applies to the 2 NPT size only.
These choices help teams match the isolation ring to the process media and application. In addition, the NSF-61 compliant configuration uses 316L stainless steel with EPDM. This gives water and wastewater applications an option for approved use when that configuration fits the project.
Body and Instrument Fitting Options
The Ashcroft 82 threaded isolation ring also offers practical non-wetted component options. The body is available in carbon steel or 316 stainless steel, giving teams flexibility when matching the unit to site preferences, installation standards, or surrounding piping requirements. Instrument fittings include 316L stainless steel adapters and a 316L stainless steel needle valve option. For configurations with Safe Quick Release™ (SQR™), the SQR component uses zinc-plated carbon steel.
These non-wetted options help support a reliable instrument connection without changing the process-contacting material selection. As a result, users can focus wetted material choices on the process media, while still selecting a body and fitting arrangement that suits the installation. This helps make the threaded isolation ring easier to configure for pressure gauges and other compatible pressure instruments.
Instrument Removal Options
The Ashcroft 82 offers several instrument removal options. Teams can select direct-mount, needle valve, Safe Quick Release™ (SQR™), or needle valve with SQR. The SQR option supports 360° instrument rotation and instrument removal.
This added flexibility can simplify installation, inspection, and maintenance. It also helps when teams need better gauge positioning after installation. With the right configuration, operators can access the pressure instrument more easily.
Fill Fluid Choices
The Ashcroft 82 offers fill fluid choices for different application needs. Options include glycerin, Silicone SF-96, and Halocarbon®. These fill fluids support instrument performance across a range of temperature conditions.
Because process compatibility matters, Westech Industrial can help review the application details before selection. This helps customers choose a threaded isolation ring configuration that fits the pressure instrument, process conditions, and installation requirements.
