SOSHH® Quick-Clamp PTFE Flexible Connectors provide ultimate chemical resistance (-200°C to +260°C) for aggressive acids, solvents, and high-purity pharmaceutical powder processing. Engineered with virgin fluoropolymer and a heavy-duty sanitary clamp interface, it enables 100% tool-free changeovers in under 30 seconds. Fully compliant with FDA 21 CFR 177.1550 and EU 10/2011 standards. Factory direct with zero tooling fees for custom diameters and lengths.

Handling aggressive solvents, concentrated acids, and high-purity pharmaceutical compounds requires flexible connections that eliminate chemical degradation and minimize production downtime. The SOSHH® Quick-Clamp PTFE Flexible Connector combines the ultimate chemical inertia of 100% virgin fluoropolymer with a heavy-duty quick-clamp sanitary interface.
Standard bolted PTFE expansion joints require 20 to 45 minutes of tedious bolt torqueing during line changeovers, leaving maintenance staff exposed to hazardous chemical residues. The SOSHH® quick-clamp system enables tool-free sleeve removal and replacement in under 30 seconds, drastically boosting OEE (Overall Equipment Effectiveness) in batch manufacturing.
Engineered specifically for hygienic powder transfer chutes and corrosive vapor extraction, the seamless internal profile eliminates gaps and internal seams where sticky bulk solids accumulate. This ensures 100% product discharge and seamless Clean-In-Place (CIP) nitric acid and caustic washdowns.

The multi-axial flexibility of SOSHH® PTFE sleeves absorbs continuous mechanical vibration from gyratory screeners and high-frequency separators without developing stress fractures or wall thinning.
When dosing hazardous micro-ingredients, our low-durometer, thin-wall PTFE profiles minimize axial and lateral force transfer, protecting high-precision load cell calibration.
Designed for charging reactors, fluid bed dryers, and centrifuge discharge lines handling boiling solvents, concentrated acids, and aggressive organics without extractables or leachables.
Inspect the sanitary ferrules or pipe stubs to ensure surfaces are clean and aligned within standard axial tolerances.
Position the SOSHH® PTFE connector symmetrically over the connection gap, ensuring the internal sanitary lip seats evenly against the ferrule face.
Fasten the heavy-duty sanitary quick-clamp over the integrated collar. Hand-tighten the ergonomic wing nut to achieve a 100% dust-tight and pressure-sealed joint without specialized tools.
As a direct manufacturer specializing in industrial flexible connections, SOSHH® eliminates standard catalogue limitations:
Manufactured to match any non-standard hopper, rotary valve, or ducting dimension from DN50 to DN600 (2" to 24").
No tooling, mold, or setup fees for custom diameters or non-standard installed lengths, ensuring low-risk prototyping and rapid global dispatch.
Our engineering team provides complimentary STEP, IGES, and PDF dimensional drawings within 24 hours to integrate directly into your plant layout.
