How to Choose an Abrasion-Resistant Flexible Connector
Choosing an abrasion-resistant flexible connector requires more than selecting a thicker wall. Engineers should consider the conveyed material, abrasion level, equipment movement, installation gap, temperature, pressure or vacuum, and connection geometry. This guide explains how to select TPU flexible connectors for abrasive powder handling and when a heavier-duty construction such as SOSHH PU-15 may be appropriate.

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.

How to Choose Polyurethane Flexible Connectors for Abrasive or CIP Powder Lines
Powder lines using hose-clamp connections fail most often at the clamp edge — uneven torque, vibration and CIP heat combine to tear the sleeve. SOSHH polyurethane (PU) flexible connectors use polyether TPU and a tool-free snap-in design to remove that failure mode entirely. This guide maps the material properties — abrasion, temperature, static dissipation, food-contact compliance — to each industrial application.

Improving Pipeline System Performance: 6 Benefits of Polyurethane Flexible Joints
Polyurethane flexible joints earn their place in powder and bulk-material pipelines on six measurable fronts: abrasion resistance, vibration decoupling, flex-fatigue life, tool-free service, adaptability and seal integrity. SOSHH® joints are built from 100% polyether TPU with HF-welded cuffs — 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 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. For heat or chemical duty, SOSHH grades PUHT (−20 to +150 °C) and pure PTFE (−40 to +300 °C, pH 0–14).
