Question by: Melvin M on Feb 22, 2026, 10:28 AM
Wondering what kind of temps this fitting can handle?
Answer by: Customer Support on Feb 23, 2026, 1:10 PM
This metric flareless fitting can handle temperatures up to 120°C.
Question by: Jean S on Jul 14, 2025, 11:34 AM
max operating pressure on this one is listed at 100 bar, but I saw something about Series S going up to 630, which number actually applies to this fitting?
Answer by: Customer Support on Jul 16, 2025, 9:06 AM
For this particular profile ring, the 100 bar figure is the maximum operating pressure. The Series S range of 160 to 630 bar applies to a different configuration within the broader product family, not to this LL series ring. So for your application planning, 100 bar is the number to work with here.
Question by: Jean B on Nov 16, 2025, 9:12 AM
got a 4 mm tube, will this profile ring actually match the LL series stuff or is that a different animal
Answer by: Customer Support on Nov 18, 2025, 6:01 AM
For an LL series metric flareless setup, this ring is the 4.00 mm size meant to go with 4 mm tube OD, and it follows DIN design and dimension standards.
