” I ” section extension type, For flanges below 1″ size, Optional exotic materials.
Slim “I”‑Section Extension • Perfect for Sub‑1″ Flanges • Exotic‑Alloy Ready
The I‑SECTION DIAPHRAGM SEAL from AIMS Control solves the age‑old problem of mounting pressure instruments on small‑bore, high‑pressure lines. Its narrow “I”‑profile extension slips neatly between flanges smaller than 1″, eliminating the need for bulky spool pieces while still giving your gauge or transmitter full protection from clogging, corrosion, or temperature shock.
Forged from rugged AISI 316L stainless steel (with Monel 400 or Hastelloy C‑276 upgrades available), the seal features a laser‑welded diaphragm and is factory‑filled with fast‑response Silicone DC 200 fluid. Whether you mount it directly to a pressure instrument or over a remote capillary, you’ll get dependable, linear pressure transfer across the entire ‑1 … 0 bar ➜ 0 … 400 bar range.
