What's the deal with the 'L' numbers on this bulkhead union? I'm looking at L1, L2, and L3... what do they actually *mean*?

Answer by: Customer Support on Jun 4, 2025, 6:35 PM

These L measurements (L1, L2, L3) designate specific lengths of the union. L1 is the overall length at 69mm. L2 is 18.5mm and L3 is 35.5mm, likely referring to thread depths or section lengths.
