Tri-Clamp Flexible Connection Structure
💡 Executive Summary :Core Innovation: SOSHH® Tri-Clamp (TC) Flexible Connectors combine transparent FDA polyurethane (PU) sleeves with precision SS304/SS316L ferrules and integrated O-ring gaskets.Primary User Benefit: Eliminates separate rubber washers entirely—preventing accidental gasket displacement and deadly product batch contamination in food, dairy, and pharmaceutical API lines.Fast Maintenance: 100% sanitary tool-free assembly and disassembly in under 30 seconds.Standards Compliance: Certified for FDA 21 CFR 177.2600, EC 1935/2004, and ATEX Zone 20/21/22 explosive powder environments.
In hygienic powder conveying, sifter discharge, and rotary valve connections, traditional flexible sleeves requiring separate Tri-Clamp gaskets create major operational headaches. Field operators frequently misalign loose gaskets during CIP maintenance, leading to powder micro-leakage or, worse, loose rubber washers dropping into the process stream.
The SOSHH® Tri-Clamp Flexible PU Connector solves this bottleneck with a seamlessly integrated O-ring gasket design. The transparent PU body is hot-melt welded directly to stainless steel TC quick-clamp connectors, delivering a leak-proof, zero-contamination seal every single time.
Key Features & Engineering Advantages
- Integrated Sanitary Gasket (Zero Contamination Risk): Built-in O-ring seal eliminates the need for separate loose washers. Saves installation time while completely preventing gasket displacement and batch contamination.
- Standard Sanitary Tri-Clamp Compatibility: Both ends feature precision SS304 or SS316L ferrules compatible with all standard hygienic TC clamps.
- 30-Second Tool-Free Assembly: Ergonomic quick-clamp mechanism allows plant operators to remove and reinstall flexible joints in under 30 seconds during Clean-In-Place (CIP) washdowns.
- 100% Transparent Visual Flow Monitoring: Crystal-clear PU wall allows real-time visual inspection of powder flow, bridging, and material buildup.

Frequently Asked Questions
Q: Why choose an integrated gasket Tri-Clamp flexible connector over standard sleeves?
A: Traditional sleeves require loose rubber or silicone gaskets sandwiched between flanges. During vibration or routine washdowns, loose gaskets shift, leading to powder leaks or batch contamination. SOSHH® integrated O-ring gaskets are fused directly to the ferrule, guaranteeing 100% alignment and zero gasket drop.
Q: Can these Tri-Clamp connectors withstand CIP (Clean-In-Place) washdown chemicals?
A: Yes. Our PU10, PU05, and PUHT polyurethane grades resist standard CIP sanitizers and hot water up to 110°C (150°C for PUHT). For harsh concentrated acids or solvents, select our TE02 100% PTFE flexible sleeves rated from -40°C to +300°C.
Q: Are 3D CAD STEP files available for plant equipment designers?
A: Yes. We provide free 3D STEP models and 2D CAD drawings for all standard TC sizes (DN76 to DN508). Contact our engineering desk at soshh.com to receive instant CAD files for SolidWorks or AutoCAD integration.
Q: What is the global shipping lead time for custom TC sleeve lengths?
A: Standard TC sizes ship from stock within 24 hours. Custom flange diameters or specific sleeve lengths (CL) are manufactured within 48 hours and delivered worldwide via DHL/FedEx Express in 7–14 days with DDP (Delivered Duty Paid) terms available.
