Flush Diaphragm Seals with Threaded Connection

£POA

When dealing with large pipework diameters and intense, high-pressure processing, standard instrumentation dead-zones can easily cause clogging or inaccurate readings. Our flush threaded diaphragm seals provide a heavy-duty, seamless solution. By placing the protective diaphragm flush with the process entry point, these seals eliminate pockets where thick, sticky, or crystallising media could settle, ensuring a continuous and highly accurate pressure transmission.

High-Pressure Capability with Large Threads

This configuration is specifically engineered for systems that demand larger process interfaces without sacrificing structural pressure integrity:

  • Large-Bore Process Links: Available with standard heavy-duty 3/4″ to 2″ BSP process connections (with alternative options manufactured to special order).
  • Extreme Pressure Profiles: Rated to withstand demanding industrial process environments up to a maximum of 600 bar.

Premium Build & Sector Compliance

Manufactured to strict industrial standards to support demanding UK engineering sectors, from heavy petrochemical refining to high-purity pharmaceuticals:

  • All-Stainless Construction: The seal housing and flush diaphragm are precision-machined from high-grade AISI 316L stainless steel for exceptional, long-term corrosion resistance.
  • Instrument Compatibility: Fitted with a standard 1/2″ BSP instrument connection to accept your pressure gauges, transmitters, or switches.
  • FDA-Approved Fill Fluid: Supplied pre-filled with non-toxic, FDA-approved glycerine as standard, guaranteeing process safety and zero contamination in sensitive lines.

Available Custom Options

  • Remote Capillary Line: For routing your pressure indicator away from high-vibration machinery or extreme process temperatures to a safe, centralised viewing panel or dashboard.
