Vacuum vs. Pressure: Selecting the Right Flexible Connector for Pneumatic Conveying Systems

Vacuum vs. Pressure: Selecting the Right Flexible Connector for Pneumatic Conveying Systems

Pneumatic conveying demands flexible connectors matched to the pressure regime — vacuum lines risk collapse, pressure lines risk pinholing, and both generate static in combustible dusts. SOSHH® tool-free snap-in sleeves solve each case with purpose-built grades: PU-10-VR (full vacuum to −1000 mbar with polymer reinforcement rings), PU-15 (1.5 mm wall, +0.70 bar / −120 mbar), and PU-10-AS anti-static (10⁶–10⁹ Ω, ATEX Zones 20/21/22, IEC 60079-32-2). Standard diameters run Ø102–Ø804 mm, lengths 100–1000 mm, with FDA 21 CFR 177.2600-compliant food grades.

Flexible Connectors for Vibrating Sifters  The Ultimate Guide to Preventing Dust Explosions and Material Leakage

Flexible Connectors for Vibrating Sifters The Ultimate Guide to Preventing Dust Explosions and Material Leakage

Vibrating sifters generate two industrial hazards at the connection point: combustible dust leakage and electrostatic discharge. SOSHH® solves both with HF-welded polyether TPU snap-in sleeves — 40 MPa tensile strength, ~600% elongation, Shore A 90, 39.0 mg DIN abrasion — paired with stainless spigots for a 360° tool-free, crevice-free seal. The anti-static grade (PU-10-AS) is inherently static-dissipative at 10⁶–10⁹ Ω surface resistivity, tested per IEC 62631-3-1:2023 (SGS SHMR240801578301-1) and engineered for ATEX Directive 2014/34/EU, Zones 20/21/22. Standard diameters Ø102–Ø804 mm; food grades are FDA 21 CFR 177.2600 compliant.

Powder Handling PU Sleeves for Bulk Powder Transfer

Powder Handling PU Sleeves for Bulk Powder Transfer

Bulk powder transfer wears ordinary sleeves at the wall, leaks at the clamp, and traps material in ribbed crevices. SOSHH® PU sleeves solve all three with HF-welded (high-frequency welded) 100% virgin polyether TPU — 40 MPa tensile strength, ~600% elongation, Shore A 90, 39.0 mg DIN abrasion — snapped tool-free over stainless spigots to form a 360° crevice-free seal. Standard diameters run Ø102–Ø804 mm, lengths 100–1000 mm; food grades are FDA 21 CFR 177.2600 compliant and anti-static grades (10⁶–10⁹ Ω) meet ATEX Zones 20/21/22.
