Thomas & Betts 5344 1 IN INSUL 45 DEGREE LIQ TIGHT CON

The 5344 is a 1 inch connector, so it terminates 1 inch liquidtight flexible metal conduit and threads into a 1 inch trade size knockout or hub. For other runs you need the matching trade size, not this one.

A 45 degree fitting is for when the conduit has to leave the box or enclosure on an angle, which is common where a straight run would crowd a wall, a motor frame, or a piece of equipment, and a full 90 would kink the conduit or exceed the bend you have room for. The 5344 takes 1 inch liquidtight and puts the run off at 45 degrees right at the enclosure, so the flex does less of the work. If the conduit can leave square to the box, use a straight connector; if it has to turn hard, use the 90.

Yes, the 5344 is an insulated connector. It carries a throat liner so conductors pulled through the fitting are not dragged over bare metal, which is what you want when you are pulling THHN into a motor connection or a wet location enclosure.

Malleable iron. That is the heavier-duty body choice over die cast zinc for a liquidtight termination, and it holds up where the fitting takes mechanical abuse, such as rooftop equipment, mechanical rooms, and motor whips on industrial gear.

It is a liquidtight connector, so it is built to seal the conduit entry against liquid with its gland and sealing ring when tightened properly on 1 inch liquidtight flexible metal conduit. The seal depends on the enclosure entry being an appropriate rated hub or knockout with a sealing washer, and on the conduit itself being the liquidtight type.

Plan on the 1 inch liquidtight flexible metal conduit itself, a second connector at the other end of the run (straight, 45, or 90 depending on how it lands), and a sealing washer or locknut set for the knockout if the enclosure entry is not a threaded hub. The 5344 covers one end of a 1 inch run at a 45 degree angle; it does not include conduit.
