Complete connection components
1 × JN-20T and 1 × JS-20T for inch tube; for 32 mm tube use 1 × JS-32MT instead of the inch sleeves. These are total assembly counts per body, not extra items assumed missing from supply.
Panel mounting
Match the JLN-20T bulkhead locknut and panel dimensions; confirm the supplied mounting parts separately from the tube-end nut/sleeve counts.

Select the matching 37° tube preparation and assembly components. Pressure and temperature limits depend on size, material and connection; refer to the catalog. Confirm whether matching nuts/sleeves are supplied with the body before adding separate items. Metric sleeve dimensions for JS-2MT/JS-3MT are unresolved; do not infer them from an inch dash number.
