Material Selection Guide
| Material Option | Flexibility / Parasitic Force | Abrasion Resistance | Temp Range | Best For |
|---|
| Silicone (This Product) | Ultra-Flexible / Lowest (Best for Weighing) | Low | -50°C to +200°C | Non-abrasive food/pharma powder weighing |
| TPU (Ether-Based) | High / Low | Outstanding | -20°C to +110°C | Abrasive material weighing (e.g., sugar, minerals)

Engineering Notes
|
- Installation Method: Simply slide the straight cuffs over your equipment's spigots and secure them tightly with standard stainless steel worm-gear hose clamps.
Why Engineers Choose Our Silicone Weighing Connectors (Solving Common Pain Points)
- Minimizes Weighing Inaccuracy: Stiff standard connectors introduce parasitic tare forces that corrupt load-cell readings. Our ultra-flexible 0.8–1.0 mm belly design minimizes vertical and horizontal parasitic force to protect gravimetric dosing accuracy.
- Durable Clamp Retention: Thin silicone sleeves can tear under hose-clamp pressure. We reinforce the straight cuffs to 1.5–2.0 mm for secure clamp retention and a longer service life.
- CIP-Ready & Low Build-Up: Unlike deep-groove corrugated tubes, our lantern-shaped bellows have a smooth inner wall that reduces product accumulation and simplifies Clean-In-Place (CIP) washing.
Typical Industrial Applications
This HC hose-clamp style silicone flexible compensator is widely specified for:
- Loss-in-weight (LIW) feeders & Gravimetric dosers
- Load-cell hoppers and micro-dosing scales
- Vibratory weigh feeders in pharmaceutical cleanrooms
- Sanitary powder and bulk solid transfer in food processing plants
- Volumetric to gravimetric system upgrades
Custom Manufacture & RFQ Guide (For Procurement)
As a direct manufacturer, SOSHH provides rapid prototyping and bulk manufacturing for non-standard flexible connectors. To request a fast quote (RFQ), please provide our engineering team with the following details:
- Pipe Outer Diameter (OD): Top and bottom dimensions (e.g., ID 100mm to ID 100mm, or custom reducers like ID 85mm to ID 100mm).
- Total Length (L) & Cuff Length: Standard cuff length is 30mm for hose clamping, but can be extended upon request.
- Operating Environment: Mention if your system involves positive/negative pressure, or specific abrasive materials (we may recommend TPU instead of silicone for high-abrasion contexts).
