Question by: Rick R on Oct 18, 2025, 6:15 AM

flange size is listed as 1 inch on this plug, does that mean the J Max dimension of 1.565 is what i'd be matching up against my current assembly?

Answer by: Customer Support on Oct 19, 2025, 6:49 AM

The J Max and J Min dimensions, 1.565 and 1.560 respectively, represent the tolerance range for the mating surface fit. When checking your assembly, you want your bore or receiving feature to fall within that range for a proper connection. The flange size of 1 refers to the nominal classification within the 1943-61 series, so both values work together when confirming fitment.
