  • Plast-O-Matic GGMU Diaphragm Seal

    , ,
    Item Type Style Connection Wetted Material
    Flow Through Clamped Threaded Plastic

    Plast-O-Matic® series GGMU gauge guards are designed for ultra-pure liquid systems and to eliminate piping dead-leg that can harbor bacterial growth or other contamination. This is in addition to their basic function of keeping system liquid from coming in contact with a pressure (vacuum) gauge or other pressure instrument while still maintaining the accuracy of the gauge or instrument.

  • Ashcroft 106-206 In-Line Flanged Diaphragm Seals

    Item Type Style Connection Wetted Material
    Flow Through, Industrial Welded 1/4 NPT, 1/2 NPT, Flanged, Other Metallic, Stainless Steel

    The Ashcroft® 106 and 206 in-line flanged diaphragm seals or isolation devices protect pressure measuring instruments. Mounted in-line to the process piping, they are used on applications where continuous flow prevents process clogging or accumulation, while preventing process fluid loss in the event the measuring instrument is removed or fails. An ideal choice for satisfying challenging installation requirements.

  • Ashcroft 200 Diaphragm Seal

    Item Type Style Connection Wetted Material
    Flow Through, Industrial Welded Threaded, Flanged, Saddle Weld Metallic, Plastic

    Ashcroft® series 200 and 201 large diaphragm seals protect pressure measuring instruments. A metal diaphragm is welded to the top housing. Elastomeric diaphragms are bonded to the top housing. Either provides a double positive seal. They are commonly used for elevated process temperatures, corrosive service, isolation of the process for safety, suspended solids in the process, sanitary connections, replacement of process dead leg, and to ease cleaning between batches.

  • Ashcroft 81 Diaphragm Seal

    Item Type Style Connection Wetted Material
    Flow Through, Industrial Capsule Flanged Metallic, Plastic

    Ashcroft® series 81 isolation rings are mounted inline with process piping. Used for process protection of measuring instruments, the ring design eliminates process accumulation, assuring reliable and accurate pressure readings. These are ideal instruments when reliable and continuous pressure measurement is needed.

  • Ashcroft 82 Threaded Isolation Ring

    , ,
    Item Type Style Connection Wetted Material
    Flow Through, Industrial Welded 1/4 NPT, 1/2 NPT, Flanged Metallic, Stainless Steel

    The Ashcroft® 82 isolation ring or isolation device is threaded in-line with process piping. Used on threaded piping systems for protection of measuring instruments. The “ring” design eliminates process accumulation, assuring accurate pressure readings.

  • Ashcroft 80 Diaphragm Seal

    Flow Through, Industrial Capsule Flanged Metallic, Plastic

    Ashcroft® series 80 isolation rings are mounted inline with process piping. Used for process protection of measuring instruments, the ring design eliminates process accumulation, assuring reliable and accurate pressure readings. These are ideal instruments when reliable and continuous pressure measurement is needed.

  • Ashcroft 100 Diaphragm Seal

    , , ,
    Item Type Style Connection Wetted Material
    Flow Through, Industrial Capsule Threaded, Flanged, Saddle Weld Metallic, Plastic

    Ashcroft® series 100 and 101 large diaphragm seals protect pressure measuring instruments. The top housing and diaphragm capsule are interchangeable with all Ashcroft bottom housings. They are commonly used for elevated process temperatures, corrosive service, isolation of the process for safety, suspended solids in the process, sanitary connections, minimizing process dead leg, and to ease cleaning between batches.

  • Ashcroft 300 Diaphragm Seal

    , , ,
    Item Type Style Connection Wetted Material
    Flow Through, Industrial Clamped Threaded, Flanged, Saddle Weld Metallic, Plastic

    Ashcroft® series 300 and 301 large diaphragm seals protect pressure measuring instruments. An elastomeric or Teflon® diaphragm is clamped securely between the top and bottom housing with clamp rings, ensuring a positive seal. They are commonly used for elevated process temperatures, corrosive service, isolation of the process for safety, suspended solids in the process, sanitary connections, replacement of process dead leg, and to ease cleaning between batches.

  • Ashcroft 400 Diaphragm Seal

    , , ,
    Item Type Style Connection Wetted Material
    Flow Through, Industrial Welded Threaded, Flanged, Saddle Weld Metallic, Plastic

    Ashcroft® series 400 and 401 large diaphragm seals protect pressure measuring instruments and are recommended for use where clamp joints are not acceptable. They assist in controlling plant emissions by helping prevent potential leakage of hazardous chemicals. They also prevent inadvertent disassembly. All stainless steel construction is standard, with other materials available.

  • Noshok 40 Flow Through Diaphragm Seal

    ,
    Item Type Style Connection Wetted Material
    Flow Through Clamped 1/4 NPT, 1/2 NPT Stainless Steel

    Noshok® series 40 flow-through annular style, replaceable diaphragm seals are designed for completely isolating instrumentation from the process flow and preventing plugging. The process liquid flows through the pipe exerting pressure onto a flush-mounted flexible inner cylinder containing clean, captive liquid.  They are commonly used for slurries, heavy sludges, chemical – synthetic polymers, diffusers – flow measurement, and abrasive media.
