Product Overview
The Hygienic Ferrule Sight Glass is an essential monitoring component in sanitary piping, allowing operators to visually verify product color, clarity, and flow movement without breaking the sterile seal. Its streamlined, “straight-through” design ensures there are no pockets where product can stagnate.
360° Visual Monitoring
Unlike flat-plate windows, our inline ferrule sight glass provides a full 360-degree view of the process media. This is critical for detecting turbulence, air bubbles, or contamination in real-time. The glass is held securely between two stainless steel ferrules and protected by a robust cage or outer sleeve to prevent accidental breakage in busy industrial environments.
High-Integrity Aseptic Materials
Safety and purity are at the core of this design. We utilize Borosilicate Glass, which offers exceptional thermal shock resistance and chemical durability, allowing the unit to withstand rapid transitions between process temperatures and high-temperature Steam-in-Place (SIP) sterilization. The AISI 316L wetted parts and FDA-approved gaskets (EPDM or Silicone) ensure the unit is fully compliant with 3-A and global hygienic standards.
Rapid Maintenance & Installation
Designed for the modern B2B process skid, the ferrule ends allow the sight glass to be installed or removed in seconds using standard tri-clamps. The “dead-leg-free” internal geometry supports efficient Clean-in-Place (CIP) cycles, ensuring that no microscopic residue remains between batches.
