Full vacuum rated clear polyether TPU sleeve with non-metallic rings. +1.0 bar / -1000 mbar, Shore A 90, 40 MPa, FDA 21 CFR 177.2600. Ø102–804 mm, 100% metal-free bore.
Entity-Dense Summary: The PU-10-VR is a vacuum-reinforced snap-in flexible connector sleeve built from a 1.0 mm transparent polyether TPU wall with non-metallic, high-elasticity polymer rings housed in HF-welded exterior pockets. This ring-and-pocket architecture prevents sleeve collapse under full vacuum down to −1000 mbar (−14.5 psi), while sustaining positive pressure up to +1.0 bar (+14.5 psi) — without putting any metal in the product path. Because the reinforcement is non-metallic and sits outside the bore, the PU-10-VR passes metal detectors and is FDA 21 CFR 177.2600-compliant (Report TQT4821B36E). It installs tool-free in under 30 seconds per end and is fabricated in Ø102–804 mm × 100–1000 mm.
Standard flexible sleeves collapse when a conveying line pulls vacuum. Operators compensate by adding metal support rings or helical wires — but those introduce metal into the product path, trigger metal-detector rejects, and create crevices that trap powder during CIP. The PU-10-VR eliminates these compromises:
| Vacuum Challenge | PU-10-VR Engineering Solution |
|---|---|
| Sleeve walls suck inward and choke flow under vacuum | Non-metallic polymer rings hold the bore open down to −1000 mbar full vacuum |
| Metal support rings in the product path → rejects | Rings are non-metallic and seated in HF-welded exterior pockets — 100% metal-free bore |
| Wire-reinforced sleeves flex → wire fatigue & puncture | Polymer rings are high-elasticity: no metal fatigue, zero puncture risk |
| Crevices trap powder and slow CIP drainage | Zero-crevice bore, flush, smooth, and free-draining |

Accumulating oversize debris, foreign matter, and agglomerates on screener discharge ports traditionally requires clumsy buckets, taped bags, or heavy clamped metal bins that leak dust and slow down cleanouts. SOSHH Snap-In Clear TPU Collection Blanking Socks provide a hygienic, 100% dust-tight, and liquid-tight collection receptacle. Manufactured from high-transparency, ether-based polyurethane (FDA 21 CFR 177.2600 compliant), these socks allow operators to monitor fill levels instantly without opening the process stream. The top snap-in cuff locks into standard SOSHH and industry-standard spigots in under 30 seconds without tools, providing a completely crevice-free transition that meets strict cGMP cleanroom standards.
Relieve Hopper Air Displacement While Capturing 99.9% of Sub-Micron Dust Rapid powder batching and gravity filling displace huge volumes of air inside hoppers, bins, and loss-in-weight feeders. When sealed with solid impermeable sleeves, this air displacement causes positive pressure surges that blow out gaskets, aerate powders, and cause erratic weighing errors on load cells. SOSHH Snap-In Breather Bags provide controlled, continuous pressure relief while retaining fine airborne particles down to 1 micron. Constructed from breathable polyester needle felt (FM1) and featuring an integrated snap-in seating band, these bags install tool-free in under 30 seconds directly into standard industry spigots. standard industry spigots or standard SOSHH spigots The heavy-duty top loop handle allows effortless overhead suspension to prevent bag sagging during idle cycles.
Engineered for differential pressure relief and dust-tight venting in powder handling systems, the SOSHH SF-Series Breathable Snap-In Connector replaces traditional clamped cloth sleeves. Featuring standard food-grade woven polyester with antistatic grid lines ( LM4 equivalent), high-air-permeability PP06, or heavy-duty PTFE-membrane needle felt (PE20), it snaps directly into grooved spigots in 30 seconds without tools. Certified to FDA 21 CFR 177.1630, it delivers continuous air venting (10-25 L/dm2/min) while containing ultra-fine powders in silos, sifters, and bulk bag filling lines.
High-performance anti-static PTFE snap-in flexible connector engineered for ATEX dust explosion zones and high-temperature powder handling systems. Featuring a conductive black fluoropolymer film with continuous 316 deg C (600 deg F) thermal stability and surface resistivity under 300,000 Ohms/sq, this tool-free snap-band sleeve provides an airtight, zero-leakage seal for vibratory sifters, fluid bed dryers, and pneumatic conveying. Designed as a direct drop-in replacement for standard spigot grooves and modular sanitary ducting, it guarantees universal chemical resistance (pH 0-14) with zero cross-contamination.
SOSHH® Inflatable Snap-In Flexible Connectors provide 100% dust-tight pneumatic sealing for FIBC bulk bag filling, discharging, and toxic powder transfer. Engineered with FDA-compliant Ether TPU and integrated pneumatic air fittings, the inflatable bladder expands at 1–2 bar to lock container necks securely, preventing airborne dust escape.
