Questions about this item

Does the UNF75NR come with any gaskets or locknuts, or must those be purchased separately?

The rigid union is supplied as a single 3/4 in FNPT x 3/4 in FNPT steel fitting; gaskets and locknuts are not included and must be sourced separately.

The listing shows only one trade size — how do I know the 3/4 in version is the correct choice for my conduit run?

Match the union to your conduit trade size; this unit is built for 3/4 in rigid conduit in either vertical or horizontal orientation, so select it only when your raceway is also 3/4 in.

What does the Class I Division 1 rating actually allow when the union is installed in a live hazardous-area system?

The fitting is certified for Class I Division 1 and 2, Groups A through D, plus Class II Division 1 and 2, Groups E, F, G and Class III, permitting use in atmospheres containing flammable gases, vapours, combustible dusts and ignitable fibres.
