Where Tubing Failures Hit Hardest (High-Frequency Trouble Spots)

1) Sealant / Adhesive Dispensing Lines

Common pain: material build-up, sticking, deposits that cause flow drift; viscosity changes with temperature.
Upgrade direction: low-adhesion liners, smoother inner surfaces, optimized ID tolerance, and (when needed) temperature-control options (design-dependent).

2) Solvent Cleaning Loops / Flush Circuits

Common pain: swelling, hardening, cracking; residual contamination after cleaning.
Upgrade direction: stronger chemical resistance, low extractables, and stable batch consistency.

3) Lubrication & Oil Delivery Circuits (fixtures, tooling, moving equipment)

Common pain: compatibility issues with additives, seepage, and poor abrasion resistance.
Upgrade direction: chemical/oil-resistant designs with abrasion jackets and anti-kink protection.

4) Pump-Driven Sections with Pulsation (metering pumps, gear pumps, piston pumps)

Common pain: pressure pulses loosen connections, cause blow-off risk, or accelerate fatigue failure.
Upgrade direction: reinforced construction, pulsation-aware design, and anti-blow-off fitting strategies (design-dependent).

5) Robot Arms & Cable Chains (high-cycle motion)

Common pain: jacket wear-through, fatigue cracks at bend points, kink damage in tight routing.
Upgrade direction: minimum bend-radius optimization, abrasion sleeves, spring guards, and split routing (fixed section + moving section).
