Is the Universal industrial worm band ASFA-L 9 mm, stainless steel suitable for food-grade applications and compliant with DIN 3017 and RoHS 2002/95/EC?

Yes. The Universal industrial worm band ASFA-L 9 mm, stainless steel is suitable for foodâgrade applications and compliant with DIN 3017 and RoHS 2002/95/EC. It is manufactured entirely from AISI 316 stainless steel (W5), recommended for the food, chemical and marine industries, and produced in accordance with the requirements of the DIN 3017 standard and the RoHS directive 2002/95/EC. Its smooth inner band and coldâextruded thread minimize hose damage, making it appropriate for hygienic food applications.

Can Universal industrial worm band ASFA-L 9 mm, stainless steel withstand corrosion in marine and chemical environments over long-term use?

Yes. Universal industrial worm band ASFA-L 9 mm, stainless steel, made entirely of AISI 316 (W5), is specifically specified for food, chemical and marine industries and manufactured to DIN 3017 and RoHS. AISI 316 offers excellent resistance to chloride-induced corrosion and many chemical exposures, so the clamp will withstand long-term use in typical marine and many chemical environments. However, absolute longevity depends on specific conditions (concentration and temperature of chemicals, continuous immersion, galvanic coupling, cyclic loads). For highly aggressive media (strong acids, concentrated chlorides at high temperature) or for critical long-term deployments, verify compatibility with the exact environment or consider higher grades/coatings and periodic inspection.

What torque range should be applied when tightening Universal industrial worm band ASFA-L 9 mm, stainless steel to avoid hose damage?

For Universal industrial worm band ASFA-L 9 mm, stainless steel, a safe tightening torque range to avoid hose damage is approximately 1.5â3.5 NÂ·m (13â31 inÂ·lb). Rationale: the clampâs coldâextruded smoothâinside 9 mm band and compact worm mechanism allow secure multiple clamping at relatively low torque. Start at the lower end (â1.5 NÂ·m) and increase only as needed to achieve a leakâfree seal, not exceeding â3.5 NÂ·m to minimize risk of compressing or cutting the hose material. For soft or thinâwalled hoses (silicone, EPDM, PVC) prefer 1.5â2.5 NÂ·m; for sturdier industrial rubber hoses 2.5â3.5 NÂ·m. Always verify with a pressure test after fitting.
