Aplisens Threaded Diaphragm Seals

Aplisens Threaded Diaphragm Seals are engineered to protect pressure measurement instruments from harsh, corrosive and viscous process media. These seals isolate transmitters and gauges from direct contact with process fluids while ensuring accurate pressure transmission.

At The Transmitter Shop (TTS), we offer a complete range of Aplisens threaded diaphragm seals designed for demanding flow, level and pressure applications across diverse industries. Built with durable materials and precise construction, these seals deliver reliable performance in high-temperature and high-pressure environments.

Key Features of Aplisens Threaded Diaphragm Seals

  • High durability & corrosion resistance: Aplisens seals are available in materials like stainless steel, Monel, Hastelloy, Tantalum, Titanium and others, tailored to resist aggressive media.  
  • Threaded compact design: The threaded models (such as S-Comp, S-Comp 10 MPa, S-CompCh, S-Mazut, S-RC) offer secure, leak-resistant threaded process connection, suitable for tight spaces while ensuring reliable sealing.
  • Large diaphragm & flush options: Some threaded models include large or flush diaphragms, which help improve response time, reduce media trapping and simplify cleaning.
  • Wide pressure & temperature ranges: Depending on the model and material, pressure ratings up to 10 MPa (or more in specific designs) with appropriate temperature stability.
  • Chemical / sanitary compatibility: For chemically aggressive media, Aplisens offers “Chemical” or “Ch” variants (e.g. S-CompCh), with materials resistant to corrosion and special construction to prevent contamination.
